BatoForge strategy notes

Using Twins

When a merge produces a level 3 Batomon, Twins gives you an exact copy with a sell value of 0. The payoff is a second unit for the board, so it helps most when both copies have a role.

When it fits

Look for a realistic level 3 route and enough support for a duplicate. Constantly replacing your core before its final merge leaves the Trainer waiting for a milestone you may never reach.

How to use it

Track remaining copies while preserving current battle strength. At the level 3 merge, compare a two-copy formation with the varied roles already on your board.

Example

Under the standard recipe, six level 1 copies make two level 2s and then one level 3. Twins would grant its copy at that last merge, with no sale income from the reward.

What you give up

The extra unit can compete for support positions. Version 1.3.0 fixes immediately post-merge buffs reaching the copy, including Silver Watch’s Cooldown Speed and Aviarab’s armed charge.
