[Release] Custom Death States
Is the default "knockout" state not enough for your needs? Do you need the party to lose the battle if everyone was petrified, paralyzed, or asleep?

This plugin allows you to designate additional states as "death" states, which would tell the engine to treat battlers as dead if the state is applied.
