We didn't get this far last week (I know, we're slackers). So I was reading up on him and I had questions.
I read that paladins could cheese the Grasping Hands through bubble/bop. If there's a rune that nobody stands on, do hands come up anyhow? Can mages iceblock through the ground slam/knockup, or hunters deterrence through, thus lessening the dps and healing requirements? Can a warlock or monk teleport out of a hand? Can a mage blink out of a hand?
I know we'll get to this soon enough and I can find out for myself, but it's quicker to ask you all.
