Ok, so buffs are timed? Good to know, but also unfortunate info can't be made clearer. I'll make do.
Bottled wind, the move, or bottled wind, the item? in the case of the former it self targets (to my knowledge, maybe i need to double check), but in the case of the latter i may not have been using it as intended (been exclusively using the move not knowing any better), so that's likely on me.
is there a bag sort button, btw? would help organize between battle items and key items and other items.
I feel like it had something to do with one of the moves the enemy was using? but i couldn't tell you what. it wasn't like normal poison that ticked down your hp super fast. do you have any other status conditions in the game that inflict damage?
no particular comment on the chest double check (i don't think it's extreme enough to remove, but i wouldn't mind its absence)
