When Desmond's Efficient Death Dweomer is cast, the caster must hit a living target at AC 10, lowered by dexterity modifiers and magic armor bonuses, if any. If the wizard strikes the target, they instantly fall unconcious for the remainder of the spell, but they do not lose any HP. To anybody else watching the event other than the caster, it appears that the victim has suffered a horrible death at the wizards hand by fire, being turned inside out, etc. Actually, this is an illusionary effect, the victim has just been knocked out. Anyone seeing this "death" must make a save vs paralyzation or one of the following occurs- roll 1d10:
The Wizard can only strike one target during the spell, and the target looks, feels, and appears dead by all means until the spell is over.
