Update: it’s definitely something with the AI. Even the supercomputer intelligence of Turo decided that the best way to deal with Ice Face was to have his Iron Bundle use Snowscape…five times in a row.I’m not sure if this is stupidity or genius, but I thought this was interesting.
Alfornada Gym in Violet, the second trainer has a Medicham that knows High Jump Kick/Psych Up/Acupressure/Power Trick. Against my Eiscue with Ice Face up, the Medicham just refused to use High Jump Kick despite that being the only offensive move it has. I assume it heavily discouraged selecting HJK due to the crash damage (I don’t know for sure if crash damage applies when attacking into Ice Face, but I assume it does), and instead decided to…spend multiple turns using useless stat modifiers.
This Medicham is evidently a loyal follower of OSHA.
