WTB that spell

So I'm happily questing around Scourgeholme in Ice Crown, not really paying much attention to what I'm doing. There are some skeletons and some insects and a couple of things that look a bit like that boss at the end of Arcatraz that does that mega mind flay. And suddenly it's casting mind sear on me and I think 'haha, even the npcs don't know how to use it properly'. And then I notice it's doing damage. To me. The target. It's alright for some.
