Extrapolating my current Six Person Group to Level 12 I believe that the Angel of Emptiness would be able to kill the entire party!!! Even its third attack will hit often when Magical Armor Class Bonuses are removed and a Difficulty Class 22 Fortitude Saving Throw will be very difficult once Magical Saving Throw Bonuses have been removed. 10 points of Damage Reduction that is unsurpassable combined with Magical Damage Bonuses being removed reduces the amount of damage output by quite a bit!! How would a Level 12 party kill this guy?
