The Dockers' Friendship

Buff. Increases DMG dealt by 20% and DEF by 60%. When defeated, returns to battle, and recovers 5% HP, the character suffers [stunned]. When one enemy's turn ends, if all allies in battle are [stunned], the battle ends; otherwise, dispels [stunned], the character deals 5% more DMG, and the DMG taken increases by 5%. Stackable, there's no upper limit. Cannot be dispelled and ignores immunity.
