I was attacking Hel in raid and even though she got her ability on my guys, I was still gaining mana (and used several abilities). Anyone else see this too?
Don’t say this too loud!
I’ll admit I have an ulterior motive - I have a Hel on my bench at the moment. 
Nope, she seemed to work just fine on the attack I experienced.
Side question: I have only seen her once. Do many people have her or is she ultra-rare?
