As the title suggest, I'd like to write a custom ability that raises sp.a and sp.d of the user when its stats are lowered. But I've figured out that the effect of a similar ability: Defiant is processed in battle logics instead of an inside ability event, so it's kinda hard to write a similar one.
Hope that there'll be an related ability event in Ability interface named like , so I can implement my custom ability. Thx!
