This one is kind of obscure: When exactly will a pinch berry (Salac, Petaya, etc) activate on a cartridge?
http://upokecenter.com/games/dp/guides/holditems.php states: "If an item's description includes "when", it triggers at the end of a Pokémon's turn, after an attack is used (before fainting if any, but not Pursuit as an opponent is about to switch), at the end of every round, and whenever a Pokemon, including the holder, becomes active (including when a battle begins)."
However, I'm not sure if the berries are supposed to activate due to hazard damage (Does a pokemon "become active" before or after hazards?), or if they're supposed to activate due to Sand or Toxic/Burn damage (When during the End of round sequence does their step go off?).
