Back when the level cap was 10, if you ran von 3 on elite that wizard at end would cast acid fog. We got that spell when we were able to cast 6th level spells.

The same thing happened when the titan raid came out. The bugbear at end of the higher level Cartmon's quest would cast that cool dancing ball. We got that spell also when 6th level spells were added.

Since we now have access to 9th level spells, how bout letting us have that sweet uber stone skin spell that the wizard has in offering of blood. I have no clue what level it is but I doubt its an epic spell.
