If an incapacitated target is within five feet of the vargouille, the vargouille can kiss that creature, which must succeed on a DC 12 Charisma saving throw or become cursed. The cursed target loses 1 point of Charisma at the end of each hour, as its facial features take on a fiendish aspect. The curse is held at bay by direct sunlight or the daylight spell. Once the cursed target's Charisma drops to 2, it suffers an excruciating, violent death as its head tears away from its body to become a new vargouille. The curse can be ended only by a remove curse or greater restoration spell. The physical changes are undone when the curse ends through these means.
