What this update means for your run

The Mythical update adds a rarity above Legendary, ranked play, and new Trainers and Trinkets. It also replaces cooldown reduction with Cooldown Speed, changing the arithmetic for faster casts.

  • The announcement’s +100% example turns six seconds into three. With the same frequency formula and only +50%, six seconds would become four.
  • Mythical Batomon are outside ordinary shop stock. Check the relevant Trainer, Trinket, or event for the acquisition route.

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.
