Hi there!
First off I'm loving this so far, I'm all the way in Mount Battle already and having a blast!
I just wanted to let you know (though I'm sure you already do) that the damage calculation for hitting oneself during confusion seems to be off. I believe I was fighting Nosh (Sosh?) but it was an arbok. It had +4 stages of attack and -2 stages of defense yet still barely scratched its own health bar.
Keep up the great work!
