A succubus drains energy from a mortal she lures into an act of passion, such as a kiss. An unwilling victim must be grappled before the succubus can use this ability. The succubus's kiss bestows one negative level. The kiss also has the effect of a suggestion spell, asking the victim to accept another act of passion from the succubus. The victim must succeed on a DC 22 Will save to negate the suggestion. The DC is 22 for the Fortitude save to remove a negative level. These save DCs are Charisma-based.
