Dungeon scaling? Spell and trap damage is lethal in a full/half full party, and tolerable when solo or with a hire .
"Dead Pykzyl's disintegrate hit you for 616 points of damage." With 3 players and 2 hires in party. If I were solo, it would probably be half of that, and wouldn't be an insta kill for 90-95% of lvl 17 toons.
