Brutallis (River of Flame Map): Immune to damage?

[Endarire]

I'm on Normal difficulty. This unique Balrog-looking creature was immune to cold, electricity, fire, and raw magic damage except Bone Spirit, and even then, it only took about 22 damage per hit. I was barely hurting it, and even with Mana Shield, I was barely surviving a hit or two from this thing. This creature seems massively overturned for a Normal difficulty gold name!

Pweath fix.

Thankee!
