My son and I are unsure of the dynamics on abilities and damage with respect to weakness and resistance. He was using Tyrogue’s Bratty Kick against my psychic pokemon. My pokemon has a -30 resistance to fighting so I think it should result in 0 damage. My son says it’s an ability and not an attack so therefore the damage goes through. I can find no rulings that support either side. I am new to the game and he has been playing for a few years so I’m deferring to his knowledge. That said, a ruling either way would be helpful. If this has been discussed in the forums it’s in a place I can’t find so sny help is appreciated. Thank you.
