Kiss of the Succubus
Level 5 · Necromancy · Ritual · Concentration
You kiss a willing creature or one you have charmed or held spellbound through spells or abilities such as [dominate person](https://api.open5e.com/spells/dominate-person). The target must make a Constitution saving throw. A creature takes 5d10 psychic damage on a failed save, or half as much damage on a successful one. The target’s hit point maximum is reduced by an amount equal to the damage taken; this reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.
