This guy seems pathetic in comparison to a 26th level fighter/wizard/warlock. Unless the damage capabilities of characters is massively toned down from 3e to 4e, this pit fiend is a joke! 1-12 + 11 dmg + 5 fire (or all fire?) is just pathetic in the extreme. A decent fighter of 10th level can exceed this easily. Imagine a warlock with hideous blow, lots of strength a moderate 26th level weapon (+6 big mace perhaps) and you are looking at MUCH more damage from one hit, and the warlock probably gets more than one hit! Of course this is all speculation as we do not know the mechanics yet and are really just guessing
