Once creature you kiss must make a Constitution saving throw, taking 1d12 force damage on a failed saving throw or half as much damage on a successful one.
You must be able to kiss the target’s skin (although you do not need to kiss its lips), or you can kiss it through thin cloth. If the creature is in combat, you must succeed at a melee spell attack to kiss it; if not in combat, the creature must be willing to be kissed, restrained, or unaware.
You inflict additional damage with your kiss at 5th level (2d12), 11th level (3d12) and 17th level (4d12).
