Patch 1.4.1

I missed some balance pain points for high Master rank players so I'm going to put up some balance changes. Many of these issues will be addressed further next regular patch. Basic Bait This item is rarely used by most of the player base but leads to some unhealthy strategies abused by high rank players. This is a small band-aid fix, and this item will be likely removed and replaced on the next regular patch Cost: 0 → 10 Black Belt Black Belt is currently consistently strong when forcing Beetbud and quite weak when trying to do anything else. This is also a band-aid fix. The trainer is more one-dimensional than I'd like, and will also likely be reworked on the next regular patch Lone Fighting monster's On Victory activates: at the start of battle → after each battle I'm limiting some of these trinkets to unique, since stacking them can lead to very unhealthy one-monster boards. Tempo Charm Changed to be Unique Metal Bat Changed to be Unique Ancient Plume Changed to be Unique Witch isn't overperforming too much, but has some ridiculous high rolls that needs to be more in line. Some of the weaker potions may also get a buff next regular patch. Glamour Potion Sell Value: tripled → +30 per monster Fate Potion double sell value → double base sell value Free rerolls: 10 → 8 Summon Potion Cost: 5 → 10

New Trainer! Witch Update (v1.4.0)

New Added the Witch trainer: the first shop rolled each day contains a Potion, a new family of 15 items that only she can bring to the shop. QoL Shop items that would do nothing are now greyed out and can't be bought, like a Voucher once every monster on the shelf is gone, or a Battery Pack after your last Electric monster was sold. On mobile, tapping an event option now selects it and Confirm takes it, so you can tap the reward to inspect it first. Cards now show the red LIMIT badge again when a monster's cooldown is already at the 0.1 sec minimum and more Cooldown Speed does nothing. Balance Changes Shared Batomon Gildshell Extremely high pick rate, and increases a run's winrate substantially when picked at any point. It's also overperforming even harder in higher ranks. Cost: 20 → 25 Jinto Batomon Sarudo Still underperforming and almost never played. Lowering the rarity should make it come out earlier where losing is not as punishing. Rarity: Rare → Uncommon Cost: 25 → 20 Damage: 100/200/300 → 75/150/225 Aviarab Swapped rarities with Sarudo, as this is still looking like the strongest Uncommon in Jinto even after the nerf last patch. Rarity: Uncommon → Rare Cost: 25 → 30 Damage: 15/30/45 → 20/40/60 Furnadon Scavenger paired with Furnadon is overperforming pretty hard. However, both of them seem to just average when not played together. This change to Furnadon should break their synergy without making them too weak when played on their own. Burn per trinket: 1/2/3 → 2/4/6 Duplicate trinkets: counted → not counted Emberpaw Fairly unpopular and underperforming. Burns to evolve: 25 → 20 Pantra Batomon Lignite Still underperforming, and is the least popular Rare Batomon in Pantra. Cooldown: 5 → 4.5 Water Batomon seem to be doing well late game, but are underperforming early game in Pantra. Dribblet Heal: 15/30/45 → 20/40/60 Aster Heal to adjacent Water allies: 25/50/75 → 30/60/90 Trainers and Items Bug Catcher She's overperforming when playing Guardiant and looks to be very good in both regions even when not playing Guardiant. First Bug bought each day: free → $10 off Mystic Pearl Water Batomon are underperforming early game in Pantra, so this will hopefully be a slight buff. Heal given to Water allies: +10 → +15 Green Stone Currently this can be used to gain a ton of money with multiple membership cards, so I'm limiting it once per round. Can appear in the shop: any number of times per round → once per round Bugfixes Fixed monsters attacking a fraction of a second off the cooldown their card shows. Fixed two Sirenades casting at the same moment removing every debuff instead of 75%. Fixed Pompummel replaying an evolving ally's old On Victory, so an Ignit above it got stuck as Flarilisk mid-battle instead of reaching Basilord. Fixed a silenced monster's On Victory still firing from Pompummel or Black Belt. Fixed Small Club and Giant Club keeping their Damage bonus in the shop when an ally like Shrinell or Formiqueen took the monster's cooldown under 5 sec. Fixed Black Feather wasting its Multicast on a Zephyrex. Fixed Rigged Dice picked up mid-shop rigging the refill after you bought an item, instead of the next day's shop. Fixed Mystic Incense's Mythical being lost if you quit and continued mid-day before rerolling for it. Fixed a Twins copied by Mysterious Mask not making its twin when a Mega Upgrade Disc fired on the same merge. Fixed a painted species gained onto a full board, like the Dragon Tamer's Onsetra, arriving without its paint. Fixed Green Stone's transform animation being cut short when you own Power Pouch. Fixed Noxnimbus not highlighting the Toxic allies it buffs, and Petrirex and Aerophim not highlighting the slots next to them. Fixed the Leaderboard button on the title screen not being reachable with a controller. Fixed lists on mobile ignoring a finger on the scrollbar while still coasting from a flick. The scrollbar can now also be grabbed from just beside it. Fixed stray black pixels on the trainer portraits.

v1.3.0Oct 6, 2026 · build 25738032
patch · official Steam post

Patch 1.3.0

New Master rank players can now access a Leaderboard on the title screen, showing the top 10 and the players near their rank. QoL Keyboard hotkeys: R or D rerolls the shop, E sells the monster under your cursor, and Space and H confirm and hide the end-screen panel respectively. Hovering Reroll, Confirm or Hide shows its key. The 30 FPS cap while tabbed out is now an option, Background FPS Limit in Settings, and is off by default, so a battle watched on a second monitor stays smooth. Cordycant and Aviarab now say their armed buff is lost if they're sold before it's used. Balance Changes Jinto Batomon Opalion Changed to weaken the Cairnage synergy. Cooldown: 9 → 6 Rock allies triggered: 2 → 1 Petrirex Revert the cooldown change as the scaling nerf from last patch was already pretty heavy. Cooldown: 7 → 5.5 Steamscuttle Very popular and overperforming. Cooldown: 3 → 3.5 Kappow Lower the cost so it's slightly worse as a gold gain engine. Increased the cooldown to compensate. Cost: 30 → 25 Cooldown: 4.5 → 5.5 Aviarab Giving multicast is very strong, and it looks to be overperforming, so slight nerf to the cost. Cost: 20 → 25 Dollhime Previous nerfs may have been too heavy, so giving it back some power. Damage per trinket gained: 40/80/120 → 50/100/150 Mallogre Does not see much play, and is slightly underperforming. Cooldown: 9 → 8 Danuki Does not see much play, and is slightly underperforming. Cost: 50 → 45 Sarudo One of the least popular Batomon in Jinto, and is underperforming hard. May need another round of buffs Cost: 35 → 25 Pantra Batomon Guardiant Slightly underperforming. Damage per Bug bought: 7/14/21 → 8/16/24 Noxnimbus Still one of the less popular and weaker monsters despite poison teams being pretty popular in Pantra. Cooldown: 4 → 3 Lignite Slightly underperforming at higher ranks. Burn-to-Damage multiplier: x15/30/45 → x20/40/60 Cooldown: 4 → 5 Rock types in Pantra are played very little and are underperforming. Stalagrove Cooldown: 5.5 → 4.5 Aegistruct Cooldown: 7 → 6 Geminiss Cooldown: 12 → 10 Bugfixes Fixed On Bought cards like Toximoth and Leafleap showing the run's total buff instead of what one trigger gives. Fixed buying a common Bug using up both Bargain Bin's and Bug Catcher's free buy. Bargain Bin's is used first now, so Bug Catcher stays ready for a rarer Bug. Fixed Aviarab's armed Multicast being lost when you bought a Zephyrex, which can't gain Multicast. It now waits for the next Flying Batomon. Fixed Twins' copy missing buffs the merged monster got right after the merge, like Silver Watch's Cooldown Speed or an Aviarab's armed charge. Fixed Greedy Gloves staying armed when you picked a single card from a gift, so every later gift offered Take All again. Fixed Echo Bell and Lucky Coin giving no extra item use when bought as the day's first item. Fixed Berroon's banked berries not reaching the shop once the day's item was bought, with monsters rolling in the item slot instead. Fixed Small Club and Giant Club keeping their Damage bonus when a trinket further along in the bag, like Speed Crest, took the monster's cooldown under 5 sec. Fixed Zenith Stone still boosting Cooldown Speed bonuses, like Galvanine's. Fixed Shiny Gildshell's Damage from its Sell Value only showing in battle, not in the shop. Fixed Sproutquill and Fernfowl progressing toward evolution from the bench. Like Emberpaw, they now only progress while on the team. Fixed a monster knocked out at the same moment it cast, then revived, like a Bonshell next to a Petrirex with Shikitsune, coming back with its cooldown restarted as if it had attacked. Fixed Shiny Wishwash being no better than the regular Wishwash at level 4. Fixed the Smuggler sometimes bringing the wrong mix of tiers, like 3 commons. Fixed the shop's merge preview saying LV 3 when buying a Swoonet would chain past level 3. Fixed Gemwing not highlighting the On Bought ally above it. Fixed the trinket bag blocking clicks on the Batopedia's filter buttons when left open. Opening the Batopedia, Settings or Quit now closes it. Fixed Voltalith, a retired Batomon, showing up on enemy teams. Fixed RT not freezing the shop on some Android handhelds, like the RG Rotate. Fixed the post-battle stats and Run History only scrolling on mobile when dragged from the scrollbar or the gaps between entries. Fixed players signed in through Steam on mobile having no name, so battle intros showed trainer names instead. Fixed the game failing to start on some Windows machines without Vulkan or DirectX 12, like Windows under Parallels on a Mac.

patch · official Steam post

New Trainer! Smuggler Update (v1.2.0)

New Added the Smuggler trainer, who brings Batomon from the other regions into your shop. QoL Hiding the end-screen panel now brings back both trainer badges, so you can check who you just fought without watching the replay. The game now drops to 30 FPS while tabbed out on desktop, so it no longer slows down the rest of your computer. The post-battle stats now count how many times a monster triggered, instead of counting every Multicast cast separately. Vipair now shows the On Trinket Gained keyword. Twins now says its copy starts with a sell value of 0. Some French localization were updated after review from a native speaking player. Balance Changes Jinto Batomon After last patch's Jinto nerfs, Jinto teams' median DPS is still around 1.5x higher than Pantra teams at day 10+. So I'm doing another balance pass on Jinto to tone down the more powerful Batomon. Petrirex Per ally knocked out: 30/60/90 Shield and Damage → 20/40/60 Shield only Cooldown: 5.5 → 7 Opalion Cooldown: 8 → 9 Shield: 84 → 90 Nekoffin Damage: 250/500/750 → 200/400/600 Vengrieve Cooldown: 6/3/2 → 7.5/3.75/2.5 Cairnage Shield-to-Damage multiplier: x1/2/3 → x0.8/1.6/2.4 Ninflora Cooldown Speed on victory: 12/24/36% → 10/20/30% Cawnushi Damage per knockout: 70/140/210 → 60/120/180 Shrinell Cost: 50 → 55 Shikitsune Cooldown Speed per revive: 20/40/60% → 15/30/45% Emburn Now only gains Burn from its own and its allies' knockouts, not the enemy's Burn per knockout: 4/8/12 → 3/6/9 Bonshell Damage and Shield per cast: 100/200/300 → 80/160/240 Steamscuttle Cooldown: 2.5 → 3 Cinnabark Reverted last patch's nerf. It was a little overzealous Cooldown: 5 → 4 Drumire Same as above Cost: 50 → 45 Pantra Batomon Buffing up some of the underperforming and less played Batomon in Pantra to slowly inch closer to Jinto's power level. Thorntail Damage per Poison applied: 6/12/18 → 8/16/24 Noxnimbus Poison to adjacent Toxic allies: 2/4/6 → 3/6/9 Cinderfly Cost: 30 → 25 Burn: 6 → 7 Trainers Chemist Pretty decent trainer overall, but underperforms for higher mmr players. Toxic starting Poison: +1 → +3 Redhead Same as above Burn per win to Fire monsters: +2 → +3 Gamer now tells you which Mythical it will give you from the start of the run, and you can inspect it from the trainer panel. Small buff to help players plan their run now that you can see which Mythical you will get right away. Events The traveling merchant can now offer Cordycant and Sproach for the foreign Batomon option. After last patch's change to also have the Batomon enter the shop pool, these two now have abilities that are actually useable now. Dragon Egg can now hatch Ouroblaze, Tsunamere and Stellagon. Letting it hatch any Legendary dragon is more true to the description and leads to more interesting runs. Trinkets Zenith Stone This was already one of the strongest trinket, but letting it double dip on multipliers and additive bonuses is too much No longer boosts % bonuses, such as Metal Bat and Metronome Items Crimson Ticket Too expensive for what it does Cost: 50 → 30 Bugfixes Fixed Shikitsune failing to revive an ally knocked out at the same moment it cast, such as by a Petrirex with the same cooldown. Fixed Cherubble's Protect arriving too late to save an ally that knocks itself out, like Electranade, when the two share a cooldown. Fixed Earth Crest and Sea Crest skipping monsters that start the battle with 0 Shield or Heal. Fixed Alpha Crown leaving a monster below the rest of the team when it lost a Club bonus mid-fight, and setting a monster's Damage to 0 in Extended Mode once it was stacked extremely high. Fixed Shiny Dirgefin only gaining Damage from Tier 1 knockouts it landed itself, and gaining it from knockouts that Protect blocked. Fixed a type granted by an event, like Dryad Statue's Grass, no longer counting after the monster transformed. Fixed a transformed monster hiding an armed charge it still carries, like Aviarab's multicast buff. Fixed Miasmaw gaining nothing from reaching level 4. Fixed the monster inspect sheet opened during a battle showing pre-battle numbers instead of the live ones. Fixed Sproutquill and Fernfowl's evolution progress not counting the current fight's damage when inspected during a battle. Fixed cooldowns showing 0.0 sec when they are actually at the 0.1 sec minimum. Fixed Run History not showing the monsters a Rigalord devoured. Fixed monsters and trinkets near the top of the run summary screen not responding to hover. Fixed the post-battle stats not scrolling with a controller, so the bottom enemy row couldn't be reached. Fixed long loading and stuttering at the start of battle with a very large trinket bag in Extended Mode. Fixed some text staying in the old language after changing language in Settings, including the Batopedia's filter button, its Trophy, Medal and Star descriptions, and the shop screen on Android. Fixed the Collection window flickering wider when showing the Supporter Pack hint. Fixed a finished run being lost on Steam when Steam failed to confirm your sign-in. The game now keeps playing offline and syncs the run later. Fixed Android sign-in getting stuck when the browser finished signing in but never returned you to the game. Fixed the title screen on mobile showing an outdated rank after switching back to the app. Fixed Coffee so it highlights Rattleghast, since it does repeat its ability.

patch · official Steam post

Patch 1.1.0

QoL A monster's card now shows what it sells for, in gold, next to its rarity. The end-of-run summary screen now lets you inspect monsters and trinkets. The Batopedia, Settings and Quit buttons are now on the trainer select screen too. Added Background Audio setting, on the System page under Music, that keeps the audio playing when you alt-tab away. It is On by default. The Batopedia's tabs and its close button sizes increased on mobile, so it's easier to tap with a finger. Settings now opens straight from the title screen, and Run History has moved into the menu button beside it. Balance Changes Events The traveling merchant's exotic monster now joins your shop for the rest of the run. Jinto Batomon Currently, Jinto end game is full of one-shot kills, which I think is unhealthy and unfun for most players. At days 10+, median DPS of Jinto teams are almost 2 times higher than Pantra teams. I'm aiming to get the power level of all regions into a similar ballpark, so that I can implement more cross-region mechanics or game modes in the future. Rattleghast Poison per ally knocked out: 5/10/15 → 4/8/12 Cost: 10 → 15 Petrirex Shield and Damage per ally knocked out: 50/100/150 → 30/60/90 Ginsage Cooldown Speed to adjacent Grass allies: 10/20/30% → 7/14/21% Ninflora Cooldown Speed on victory: 20/40/60% → 12/24/36% Brimtoad Burn and Poison per battle: 5/10/15 → 4/8/12 Burn and Poison: 5/10/15 → 1/2/3 Sukoi Cooldown: 6/3/2 → 9/4.5/3 Dollhime Damage per trinket: 60/120/180 → 40/80/120 Mallogre Damage and Shield per trinket: 5/10/15 → 4/8/12 Orcana Damage and Heal per Level 3+ ally: 200/400/600 → 160/320/480 Tengusto Damage per badge: 70/140/210 → 60/120/180 Danuki Share of a knocked-out ally's Damage: 100% → 70% Shiny: 120% → 84% Snapscald Heal: 50/100/150 → 40/80/120 Burn: 10/20/30 → 8/16/24 Lumijel Damage and Heal to each Level 3+ ally at the start of battle: 20/40/60 → 15/30/45 Shiny: 36/72/108 → 18/36/54 Ouroblaze Extra Burn, as a share of the enemy's Burn: 70/140/210% → 50/100/150% Cinnabark Cooldown: 4 → 5 Drumire Cost: 40 → 50 Pipskull Evolves into Ratacomb on its 3rd knockout, not its 2nd Pantra Batomon I'm also buffing up some lesser played or underperforming Pantra Batomon to help the region match the power level of Jinto teams. Clawnetic Charge: 1/2/3 seconds → 1 second at every level Multicast: 1/1/1 → 1/2/3 Galvanine Cost: 50 → 40 Torrantler Cooldown: 8 → 7 Shiny: 6.5 → 5.5 Dribblet and Emperooze Cooldown: 3.5 → 3 Panbud and Bambudo Cooldown: 5.5 → 5 Zephyrex Cooldown: 11 → 10 Noxalith Cooldown: 8 → 7 Magmalith Cooldown: 10 → 9 Pyronade Burn: 18/36/54 → 20/40/60 Coalem Shield: 450/900/1350 → 550/1100/1650 Aster Heal to adjacent Water allies: 20/40/60 → 25/50/75 Electranade Shock: 28/56/84 → 25/50/75 Event Batomon Talonite Rarity: Uncommon → Rare As a day 6 event Batomon, it's more appropriate for it to be at least Rare. This is a slight nerf since it will no longer be targetable by Basic Candy. Wishwash Slightly underperforming, so I'm upping the rarity of the trinkets it gives. Trinket rarity granted: Uncommon/Rare/Super Rare → Rare/Super Rare/Legendary Basilord Slightly underperforming, so I'm buffing the payoff. Burn: 150/300/450 → 170/340/510 Cross-Region Batomon Boomagon Boomagon is still the most popular pick in the game. It warrants a slight nerf due to how centralizing it can feel on the meta. Cooldown Speed: 4/8/12% → 3/6/9% Trinkets All of the cooldown speed trinkets are close to the most popular and most powerful trinkets of each tier, so they are getting a nerf across the board. Quick Bell, Quick Flag, Tempo Charm Cooldown Speed: 5% → 4% Speed Whistle, Silver Watch Cooldown Speed: 15% → 12% Speed Crest Cooldown Speed: 20% → 15% Blitz Bell Cooldown Speed: 30% → 25% Haste Crown Cooldown Speed: 30% → 20% Haste Orb Cooldown Speed: 15% → 10% Momentum Flag Cooldown Speed: 10% → 8% Alpha Crown Can be instantly game winning majority of games, so it would fit better as a mythical trinket. Rarity: Legendary → Mythical Items Coupon Day 1 coupon is a much stronger start than all the other items. Discount: 5 → 3 gold Gray Chip Even if you win, the payout of gray chip does not even generate as much value as the other common items. Win bonus: 5 → 15 gold Bugfixes Fixed the opponent moving first whenever both sides had a monster due on the same instant, so an enemy Vengrieve or Reapra could knock yours out before it ever triggered. Ties now resolve in the order the casts were queued, which is your side first. Fixed quitting to the main menu and continuing your run rewinding the shop, so the next reroll dealt the same shelf again and a monster you had already bought could be bought over and over. Fixed the game freezing on a black screen, sometimes for minutes, when continuing an Extended Mode run with a very large trinket bag. Fixed the game opening in a window bigger than your monitor on a fresh install, which cut off the right and bottom of the screen including the Resolution setting that would have fixed it. Fixed the game never getting past the loading screen on Android tablets and foldables. Fixed the smallest movement of a mouse or a resting controller stick dropping the shop out of controller controls, which put a held monster back, cleared the selection ring and closed the stats box mid-read. Fixed the "Progress Not Saved" popup being impossible to dismiss with a controller, which left the run needing a restart. Fixed the "Tap your new Batomon" tutorial step never accepting the tap when the buying lesson had played just before it. Fixed a shop enchantment like Aviarab advertising its current level instead of what it actually banked when you bought it. Fixed switching accounts on the same device being able to attach your profile or run save to the other account, after which nothing you did was stored: no run history, region progress rolling back, the tutorial replaying every run, and the badge case refusing to change. Fixed Android sign-in timing out on the frame you came back from the browser, so a sign-in that took over five minutes was dropped just as it landed. Fixed picking a sign-in option doing nothing while an earlier one was still waiting on the browser. Choosing again now cancels the old attempt and starts over.

Fixed being able to open Settings, the Batopedia or Quit while a tutorial step was waiting on you, which left the tutorial drawn on top of them. Fixed the Patch Notes, Mobile and Discord buttons on the title screen being unreachable with a controller.

Batomon Showdown is Available NOW! Season 1 Begins!

The big day is here! You can now play Batomon Showdown with a 35% launch discount! Steam Reviews: Your Feedback Matters I will be reading the Steam reviews as much as I can. Let me know what is working for you and what can be improved. A few words of your honest feedback will help shape future updates. 1.0.0 Patch Notes If you've been playing since the demo, there has been a lot of QoL updates along with all the new content added to the full release: New Added the Jinto region with 50+ new Batomon! Added 6 new trainers: Twins, Gentleman, Painter, Burglar, Scavenger and Black Belt. Added 30+ new trinkets. Added the Traveling Merchant and the Fossil Discovery events. Added ranked seasons. A season ends with a hard reset to Bronze 8. Added badge case skins. Added the game on Android, playable on the same account as your PC runs. Added French, Italian, Korean, Portuguese and Spanish localizations. QoL Added the Batomon inspect sheet. Right-click a monster in the shop, in battle, on an event or in the Batopedia to see its full stats, ability and evolution chain. Added a Run History screen on the main menu, showing who you fought, how long it took, and what each Batomon did. Added a Patch Notes screen on the main menu. Added a filter to the Batopedia. You can filter Batomon by type or rarity. Added a "???" tab to the Batopedia for event Batomon and mythicals. Added a Hide Usernames setting. With it on, the battle intro announces both trainers by their trainer class instead of their display name. Trinket and Batomon Start of Battle effects now animate and play one at a time before the battle starts. Added small trainer portraits to the battle scene. Protect and Silence now get an icon in the monster's corner, with a count when a status is stacked. Positional trinkets (crowns, flags, crests) show an icon now on their target slots when they are active. Added a visual effect for Batomon that have additional types from Painter, Chef, events, etc. Added a new counter UI above some Batomon, showing Berroon's berries left, Aviarab's multicast for the next Flying purchase, and Cordycant's poison for the next purchase. Knockouts from an execution now shoot a red trail from the Batomon that lands on its target. Cooldown Speed is now a keyword with a description, and the inspect sheet shows what your current Cooldown Speed actually gives you. Income is a keyword now, and a tooltip shows when you hover your $ amount in the shop. It explains income, and how much you currently get per day. The Batopedia now shows entire evolution chains for Batomon with multi-stage evolutions. The battle recap counts how many times each monster casted. The event screens carry the trainer panel and the shop rank now in the team panel. When fast-forwarding, the speed increases after the sudden death sandstorm starts. The main menu's secondary buttons moved into an overflow menu, since the title screen was getting too crowded. The settings menu split into 2 tabs now that it is starting to get too crowded with too many settings. Also redid the settings menu for mobile separately to better suit touch controls. Audio mutes now when you alt-tab away from the game. The game now reopens on the monitor you last played it on.

Mobile Version News + Small Patch

Batomon Showdown will be available for mobile! The android version will be available on Google Play Store at the same time as the Steam release on September 15th, 2026. Pre-register here! (https://play.google.com/store/apps/details?id=com.batomon.showdown) I am working to have the iOS version released at the same time, but it is having trouble getting approved in the App Store, so I can't guarantee it will be available in time. But it will be available in the future at some point! Small Patch Adjusted matchmaking so that you are much less likely to encounter teams with Dirgefin, Celestia, and Reapra. Added a link to mobile pages on the title screen.

Shopkeeper Update: New Items, Controller Support, and More! (v0.8.0)

This update adds the Shopkeeper trainer! Shopkeeper will have rarer items in the shop. There are also a bunch of new items add to the shop! There is also a new mythical Batomon! It makes mythical items appear in the shop and buffs your allies as you use more mythical items. Controller Support The game now has full controller support! You can now comfortably play Batomon Showdown from your Steam Deck. Quality of Life Changes - Optimized some connection issues. Players should be getting less "connection failed" popups. - Added the "batopedia", "settings", and "quit to menu" buttons to the event phase. - Added a label on the item shop slot that shows how many more item uses you have left. - Reduced damage number size scaling to improve late game battle visibility. - A ton of changes to descriptions to make wording more consistent. - Long usernames now automatically shrink to fit better during the battle intro animation. - If a monster has more than 4 stats, the stat labels under the monster sprites now stack upwards instead of only keeping the highest 3. Balance Changes TRINKETS Shady Contract At higher ranks, staying at lower shop ranks and farming buffs onto bugs was a very powerful strategy. I think being able to easily stay at low shop ranks forever is not a very fun or healthy way to play the game. So, I'm deciding to remove this trinket entirely REMOVED Fancy Sword There currently is too much trinket support for fast casting Batomon and not enough for slow big hitters. So reworking this one to support the later better. Reworked to give +3% damage per trinket Mini Duplicator, Mega Duplicator, Ultra Duplicator Currently, these trinket duplicate trinkets gotten from any source. However, some interactions such as doubling the Mysterious Mask gotten from Masked Man has repeatedly been reported as a bug, so it seems unintuitive. Also, having your duplicator used up by something like Wishwash's ability is also not as satisfying as having it trigger on a trinket you actually get to select. Wording and effect changed to specify that it only works on trinkets gotten from trinket gifts. TRAINERS Swim Coach Currently, the power of water Batomon are too tied to Swim Coach. I think this warrants a rework so that water Batomon could have room to be buffed in the future. However, Swim Coach is one of the 3 trainers offered to new players on their first game, so the ability must remain simple to play around. Ability reworked to: Gain a random Water Batomon each day. (Depends on your shop odds) ITEMS Focus Pill No ability teams seem to be very dominant at higher ranks. Focus Pill seems the be the most out of line support for the no ability teams. Cooldown Speed buff: 25% -> 15% BATOMON Torrantler Out of all the water Batomon, this probably warrants a buff the most. I'm going to wait and see on all the other water Batomon to see if a buff is warranted after the Swim Coach rework. Cooldown 10 seconds -> 8 seconds Bambudo Ever since mid-game base HP was reduced, on cast scaler indirectly got much worse. So Bambudo is getting a buff to compensate. Damage buff on cast: 25 -> 35 Prismagon Same rationale as above. Damage buff on cast per type: 5/10/15 -> 10/20/30 Noxalith Noxalith was underperforming and was rarely picked up, even in poison teams. Poison buff on cast: 2/4/6 -> 3/6/9 Magmalith This seems to be overperforming by a huge margin. Also, all of the suitable recipients of it's buff are also overperforming (Lignite, Blazewing, Blixie). Cooldown 8 seconds -> 10 seconds Thorntail Thorntail is underperforming by a huge margin. Damage buff per poison inflicted: 4/8/12 -> 6/12/18 Geminiss Rock teams generally struggle for most of the game until finding Geminiss. I'm going to give this a pretty hefty nerf so there is more room to buff the mid game rock Batomon. Shield buff on cast: 70/140/210% -> 50/100/150% Aegistruct Cooldown 8 seconds -> 7 seconds Stalagrove Damage gain from shield: 10/20/30% -> 15/30/45% Coalem Shield 400/800/1200 -> 450/900/1350 Wishwash Wishwash is slightly underperforming. I'm giving it some extra sell value so you get a little bump late game when you want to get rid of it. Also giving it a bit more combat power, so you lose less lives for farming trinkets with it. Sell value $0 -> $20 Heal 100/200/300 -> 150/300/450 Reapra Reapra is getting played very often in higher ranks and has a very high win rate. I'm giving it a slight nerf for now, but still going to keep an eye on this in the future. Cooldown 6/3/2 seconds -> 7.5/3.7/2.5 seconds Galvanine Seems to be slightly underpeforming. Cooldown 8 seconds -> 7 seconds Pyronade It's the least popular uncommon Batomon, since it seems players prefer to pick scaling Batomon rather than Batomon that gives immediate combat power. However it seems to be the best uncommon Batomon by a decent margin. Burn 20/40/60 -> 18/36/54 Bugfixes - Fixed a visual bug with shiny Gildshell where it's damage stat label was not updating to its current damage until it casts. Also changed its ability to calculate damage based on total sell value rather than just bonus sell value. - Fixed a visual bug where the damage number from status effects was not showing the post-mitigated damage from shield's status damage reduction. - Fixed a bug with Berroon, where it would not give and extra item use if it was transformed into it from a different Batomon. - Fixed a rare issue where if you selected a trinket too quickly on the trinket gift select menu, it would cause the game to get stuck. - Fixed a bug where the shop odds UI does not immediately update after you pick up the VIP Pass trinket.

Batomon of a species are supposed to stop appearing in the shop if you have a level 3 of that species, but these were previously bypassing that due to evolving into a different species. Now a level 3 evolved Batomon from also stops pre-evolutions from appearing in the shop. - Fixed a bug where you could not see the effects of Mysterious Mask trinkets owned by the enemy. - Capped Batomon stats (damage, burn, etc) to 999,999,999. - Gamer's ability now gives an additional $30 on day 9. - Egg Breeder's Purple Egg now gives a level 2 Super Rare Batomon, but takes one day longer to hatch than before.

Huge Demo Update: Mythical Batomon! New Trainers and Trinkets! Ranked Mode!

Mythical Batomon! Welcome to the Mythical update for the demo! This update will introduce a new rarity of Batomon: Mythical. These Mythical Batomon are higher rarity than Legendary, and are not normally available in the shop. Discover all the special trainers, trinkets and events that let you encounter these new mythical Batomon. New Trainers! Introducing 4 new trainers, with brand new, unique playstyles! New Trinkets! Alongside the new Mythical Batomon comes the Mythical trinkets! There are also a few other trinkets added as well, that may help you access the new Mythical content. Ranked Mode! Compete against challenging opponents to earn stars and climb the ranks in this new mode! Balance Changes There are too many balance changes in this patch to list in this announcement, but I'll mention one big systematic change to effects that buff cooldown. Previously Batomon and trinkets that buffed cooldown would either reduce cooldown by a percentage or reduce by a flat amount. The math behind how these stacked is fundamentally unhealthy for the game. So, all these effects have now been unified to buff a new stat: Cooldown Speed. Cooldown speed increases how frequent your Batomon triggers. For example, a +100% Cooldown Speed would double how often your Batomon triggers, so if it had a cooldown of 6 seconds, it would be reduced to 3 seconds. All Batomon, Trinkets, and Items that reduced cooldown in some way, are now changed to increase Cooldown Speed.

Demo 0.6.0 - Balance Patch

QUALITY OF LIFE UPDATES - In the end of battle stats screen, the amount of shock damage triggered is now added to that monster's damage dealt. - Added trinkets, day, and lives left info to the end of run screen. - Added a screenshot button to the end of run screen. - The Batopedia is now accessible from the main menu. - UI will now show when a Batomon is at the 1 second cooldown limit. - Added trinket, day, and lives left info to event state. - Added the function to view your team when selecting a trinket gotten from an event. BALANCE CHANGES SYSTEM When playing rock Batomon, it can feel like too much of a matchmaking coinflip if you run into Poison teams or not. Poison no longer ignores shield. Currently, shielding has a problem where shield teams want to stall but status effects naturally scales the longer the battle goes. Shield is getting resistance to status to counteract this. Damage from status effects now deal 30% less damage to shield. BATOMON Currently shield Batomon are underperforming, especially in the early game, so they're getting some slight buffs. Pebbler Cooldown 5.5 -> 4 seconds Cost $15 -> $10 Tortress Shield 200/400/600 -> 250/500/750 Craghorn Damage gained on item used: 10/20/30 -> 15/30/45 Aegistruct Aegistruct + Draconarch was already decent, so it's getting a preemptive nerf to offset the buff to the shielding mechanic Cooldown 7 -> 8 Geminiss The multiplicative scaling isn't very healthy, even though the Geminiss itself wasn't that good due to how slow it is. So, I'm changing the mulitplier from its ability to be additive (which means consecutive casts are much weaker) but making it faster and the buff bigger to offset the change. Changed the shield multiplier buff to be additive rather than multiplicative. Cooldown 12 -> 10 Buff to adjacent ally shields: 50%/100%/150% -> 100%/200%/300% Venopuff This is currently the strongest common Batomon in the first few rounds. Poison 5/10/15 -> 4/8/12 Puffloon This change mostly aims to make leveling up Puffloon more attractive. It also takes advantage of permanent buffs better this way, which is needed since currently, poison does not scale well into the late game. Multicast 1/1/1 -> 1/2/3 Poison 1/2/3 -> 1/1/1 Heal 10/20/30 -> 10/10/10 Thorntail Thorntail is underpeforming at all stages of the game even despite poison team's good early game. Damage buff on poison inflicted: 3/6/9 -> 4/8/12 Cobrex Poison teams are underperforming late game, so Cobrex is getting a small buff. Cooldown 20 -> 15 seconds Shock teams are overperforming at all stages of the game, while being very flexible and consistent to build. Most of these are getting slight nerfs Joltail Shock 5/10/25 -> 4/8/12 Ironcore Cost $30 -> $40 Humbolt This thing is still problematic since it trigger shock damage extremely fast while having decent shock application itself. Shock 5/7/8 -> 1/1/1 Damage 1/1/1 -> 30/40/45 Galvanine Scales too quickly into a fight with charges from Dracana/Ironcore. Cooldown 7 -> 9 seconds Saberhorn One of the main culprits that's causing late game fights to end insanely fast. Cooldown 6 -> 8 seconds Cooldown increase on cast: 6 -> 8 seconds Dryadell Dryadell is very much overperforming in the late game. Cooldown 4.5 -> 5.5 Zephyrex Easy access to multicast is letting stuff like Plunderbird and Humbolt run over teams late game. Cooldown 9 -> 11 Primsagon Seems to be decent, but very unpopular, so it's getting small buff. Cooldown 5 -> 4.5 seconds Mosslug Does not consistently carry early game, so it's getting a cost reduction to make it more attractive as a tempo pick up. Cost $15 -> $10 Boomagon Slight cost increase to further accentuate the tradeoff of losing more early in exchange for scaling when playing Boomagon. Cost $30 -> $35 ITEMS Purple Gift Very frustrating to get VIP Pass out of this item if you still need commons or uncommons. Will no longer give VIP Pass TRINKETS Metronome Damage buff on cast: 20 -> 10 TRAINERS Chef Currently the trainer with the highest average wins by a decent margin. He's not very popular so may be biased towards more experienced players, so just getting a small nerf for now. Burn buff: 3 -> 2 BUGFIX - Fixed level 4 Wishwash's ability not having an effect. - Fixed a bug where if a monster got fire typing from Chef's ability, and then transformed into a monster that does is not mono-type, it would still keep the fire typing. - Fixed a bug where if you had multiples of the Ancient Plume trinket, only around half of them would trigger at once. - Fixed a visual bug where when you gain the Market License trinket, the shop rank gained is not immediately reflected in the UI.

patch · official Steam post

Demo Patch 0.5.0

NEW STUFF FEATURES Add a "stats" screen to end of battles, where you can view how much damage or statuses each monster contributed to the battle. BATOMON Shock builds (especially with Humbolt) currently scales the best into late game due to the fact that cast frequency with shock scales multiplicatively with itself, since it increases the rate shock is applied and how much its triggered. Due to this, Voltalith has been replaced with a new monster to prevent easy access to permanent shock. Some shock monsters have slight buffs to compensate. Ironcore Rare, Steel Type On Cast: Charge adjacent electric allies by 1/2/3 second(s) Voltalith removed from the shop pool TRINKET The Market License item felt less like a consumable item and something more permanent, so it's been made into a trinket instead. An item with the same effect will take its place. Market License Uncommon Increase shop rank by 1 Adding some options for when players may want to stay at a low shop rank to look for common/uncommon monsters. Shady Contract Common Lower shop rank by 1. At the start of each day, gain $5 ITEMS Black Feather let certain monsters like Gaiadrasil, which can be triggered by other monsters, easily get enough damage to one shot kill opponents. Giving easy access to multicast in general is hard to balance, so the item has been removed. A few new items have been added to take its place. Black Feather Removed Golden Gift Legendary Gain a random Legendary trinket Purple Gift Super Rare Gain a random Super Rare trinket Adding some options for when players may want to stay at a low shop rank to look for common/uncommon monsters. Basic Bait Common Lower shop rank by 1 The Market License item felt less like a consumable item and something more permanent, so it's been made into a trinket instead. An item with the same effect will take its place. Apex Bait Uncommon Increase shop rank by 1 BALANCE CHANGES SYSTEM Battles still are often over near instantly endgame so I'm upping base HP once more. Base HP scaling per day increased BATOMON Humbolt Humbolt is affected the most by the removal of Voltalith so it's base shock value buffs to compensate Damage 15 -> 1 Shock 2/3/4 -> 5/7/8 Cost 30 -> 25 Clawnetic Damage 30 -> 60 Galvanine Often hits the cap of 1 second cooldown easily, and does not scale any further. This made Galvanine extremely good mid game but often worse than lower rarity shock monsters late game. Giving it more in battle scaling but reduce how quick it scales. On cast: reduce cooldown by 1 second for the battle, (NEW) and gain +2/4/6 shock for the battle Cooldown 4 -> 7 Joltail (Shiny) Shock 5 -> 5/10/15 Coalem (Shiny) It's can feel unfair to have too much damage on something that triggers at the start of battle, so shiny Coalem is getting defensive scaling instead. (Old) Start of Battle: Gain +10/20/30 Burn permanently (NEW) Start of Battle: Gain +30/60/90 Shield permanently Sirenade Endgame water teams can feel unbeatable, so their debuff removal is taking a slight hit. This might not be enough, but I'm choosing to wait and see since there is also a bugfix that will negatively impact water teams. Debuff removed on cast 25/45/65% -> 20/35/50% BUGFIX - Fixed a bug where Chef's ability was not applying to monster hatched from eggs. - Fixed a bug where the stone items were could not trigger a level up merge. - Fixed a bug where even with the VIP Ticket trinket, there was still a very small chance of getting common monsters in the shop. - Fixed a bug where a level up merge is triggered from a monster gotten from Monster Ranger's ability does not give a trinket reward. - Fixed a bug where Cinderfly, Shogapede, and Guardiant's abilities were giving double the amount of buffs they were suppose to. - Fixed a visual bug where leveling up Lignite would appear to disable its ability. - Fixed a bug where if a monster healed on the exact tick where you took lethal damage, it would always prevent you from losing. - Fixed a bug where the Coupon item's discount would be reverted from the shop if you bought any monster that triggered a level up. - Fixed a bug where Zephyrex could still get multicast in certain situations.

Demo Update - Durability Patch [v0.4.0]

Late game battles are often still finishing so fast that it's hard to understand what happened. In this patch there are across the board nerfs to late game multiplicative scaling so HP bars don't get depleting near instantly. Hopefully the nerfs are light enough players still feel significant power scaling throughout a run which is my vision for the game. The other big part of this patch is performance improvements, which there's not too much to talk about, but I've done some pretty significant rewriting of the codebase. Hopefully there's no lag anymore in late game battles. QUALITY OF LIFE UPDATES - Optimized performance to reduce lag spikes in battles. - If you lock it and there are empty slots, the empty slots will now be refilled the next day. - Matchmaking changed so new players will have slightly more challenging opponents if they are doing well. Also expanded the matchmaking pool for experienced players so they don't keep running into the same opponents. BALANCE CHANGES SYSTEM - Base HP scaling per day increased BATOMON Blixie (OLD) Whenever a Fire ally triggers, give it Burn for this battle equal to 1x/2x/3x Blixie's Burn (NEW) On Cast: Give the Fire ally to the right 1x/2x/3x this monster's Burn for this battle Cooldown 15 seconds -> 8 seconds Burn 5 -> 30 Clawnetic (OLD) Whenever an ally inflicts Shock, trigger this 1x/2x/3x (NEW) Whenever an ally inflicts Shock, Charge this by 1/2/3 seconds Cooldown 8 seconds -> 3 seconds Geminiss Cooldown 7.5 seconds -> 12 seconds Stellagon (Old) On Battle Start: Adjacent allies with no abilities gain +1/+2/+3 Multicast permanently (NEW) Ongoing: adjacent allies with no abilities have +2/+4/+6 Multicast Torrantler (OLD) On cast: Trigger all Water allies (NEW) On cast: Trigger adjacent Water allies Zephyrex On Cast: Give the Flying ally to the right +1 Multicast permanently.

Demo Patch 0.3.2 - Battle Theme Changed!

It's no secret that Batomon goes for a retro Pokemon-inspired style, but a lot of you guys have said that the battle music is uncomfortably close to the actual old Pokemon battle theme, so I'm swapping it out. There are also some other bug fixes and optimizations in this small patch. - Changed the battle theme to a new music track. - Significantly improved performance. Should almost never experience lag now, even in end game. - Fixed a visual bug where it looked like Draconarch was affecting Fumungus's ability. - Removed text about cost scaling in Market License's description since it no longer has that effect.

Demo Patch 0.3.1 - Bug hotfix

- Fixed shiny Berroon's description not displaying correctly - Fixed an issue where the game gets laggier the longer you play. (There are other still performance issues that will take some time to get optimized). - Fixed and issue where if you buy a discounted bug with Bug Collector's passive, merge to a level 2/3 and sell it, the total sell value is 0 no matter what. Now it should reduce sell value by half of the discount you got.
