Guys, i found a trick: when dustfeather becomes a warrior, battle train with him a lot, that way u can get ur health super high. I reccomend battling till u reach above 400 health, that way u can also increase ur damage
i train with dustfeather while i'm an apprentice, then when i become a warrior i basically just do a pattern of dustfeather, and then duskfall, because for me, duskfall increases your damage more than dust feather. :3
