Massive Shockwave (uninterruptable - 3 second cast) appears to do damage in front, and behind, in a cone effect. Hits for approximately 125k-150k if taken directly. Indirect hits land for varying amounts depending on position and distance. Black Breath (instant cast) lays a patch of black oil on the ground that seems to act much like Defile on the Lich King fight in ICC. Players standing in it increase the size of the patch with each tick of damage done to a player standing in it.
