i know thats super specific, but i was curious while messing around in pkhex. and i cant find anything on why it cant be a thing so i was looking to confirm that somewhere.
from what i can find, polteageist can have its hidden ability from raid battles, but i dont know what it takes to make it count as legal in pkhex no matter what i try for level or area or game(im currently testing its phony form).
i know you cant breed an antique form, that just makes a phony.
