I made a custom voiced NPC follower and gave him some dawnguard spells, and for some reason, he won't stop using sun fire on enemies that aren't undead. I tried editing sun fire to do minor fire dmg to non undead to compensate but then he stops using it on undead as well as non undead. I haven't fully tested if this problem extends to stendarr's aura, but i don't think it matters in that case since npcs use cloaks regardless of what type of enemy they are?
