Wow. I believe they’re belly-casters (you have to cast on them from melee range or they’ll resist everything). Currently there’s a bug where Bind Sight and Harmony are being “resisted” by belly-caster mobs, aggroing the target.

I don’t know why they would resist a buff. I’ll bet it lands from melee range.
