Just a note, I did this cycle a while back and I noticed THIS mob was also procing a 54 wizard spell Piller of Lightning 828 AoE based around the target, i was resisting this every time with over 204 magic resistence.

That's a triple attack of 1686 and an occasional proc of a 5000 dd lifetap. If you aren't ready to deal with spiky damage, expect this guy to mow through your crew quickly.
PS: His partner has the same abilities but is slowable. Bring a few monks to split them.
