Just looking at this exhausts me. Don't get me wrong -- big bad monsters are fine; stat blocks (that are readable) are fine; cool powers are fine --
This just turns my brain OFF in a way that I can't describe... I'm sure the creator of this beastie is a fine human being and I'm sure that he enjoys his game and kudos to him for that.
I can say with certainty that I won't be running a 4e game -- EVER!
