I've looked for this everywhere and I can't find anything.
I want to create an item similar to BlackGlasses and Charcoal - a hold item that boosts a certain kind of attack.
I'm trying to create an item that boosts the power of punching-based moves, but how would I do that? I've added the item and given it a description and everything, I just haven't figured out how to actually make it do something.
(this is for FireRed)
