Asking about the new DLC move Lash Out, are there any caveats for its effect?
Asking because Defiant/Competitive are similar and also usually trigger on stat drops, but also have some less than clear exceptions (doesn't trigger on self-inflicted stat drops, and crucially also doesn't trigger if an ally reduced its stats in doubles).
I can't really think of a potential situation where the pokemon using lash out could lower its own stats before using lash out without manufacturing an unrealistic setup, but does anyone know if an ally lowering stats triggers the power boost?
