I can do what?

In my last post, I lamented that, although my newly-shadow priest is killing things quickly, she has no AoE.  But ho, what is this?  She dinged 75 last night, and one of her new skills is an AoE: mind sear.  I went to bed straight-away after training and haven't gotten to play with it, but, ooh, it feels like Christmas.  :)
