Since there is no 'lower-level' raise dead nor are resurrection spells available; massive damage spells, Coup de Grace attacks, (or any attack that says SAVE or DIE) instead does the equivalent amount of 'sneak attack' dice by the attacker's level... exactly as though performed by the rogue class. The victim of such an attack may be left in immediate danger of bleeding to death or somehow have survived to exact his revenge.

Characters who are 'killed' may recover in the normal ways from negative hit points, but typically they are unable to act for the rest of the current encounter.
