Vargouille

The vargouille kisses an adjacent creature that's asleep, Paralyzed, or Unconscious, exposing it to the vargouille transformation disease.

The vargouille shrieks, its scream so terrible that all non-vargouilles within 60 feet must succeed at a DC 16 fortitude save or be Paralyzed for 3 rounds. The effect ends early for a creature if the vargouille moves out of sight, moves farther than 60 feet from the creature, or attacks the creature with its fangs. After attempting its save, a creature is immune to that particular vargouille's Shriek for 24 hours.

Exposing the victim to sunlight or any light spell of 3rd level or higher pauses the progression of the disease until the victim is no longer in light. Saving Throw DC 18 fortitude Stage 1 carrier with no effect (1d6 hours hours) Stage 2 victim's hair falls out (1d6 hours hours) Stage 3 victim's ears grow into leathery wings, tentacles sprout on the chin and scalp, and the teeth become long, pointed fangs (1 day) Stage 4 victim's mind regresses to a vicious and unintelligent shell of its former self (1d6 hours hours) Stage 5 victim's head breaks free of the body (which dies) and becomes a new vargouille

Saving Throw DC 18 fortitude Stage 1 Damage the victim has taken from vargouille fangs can't be healed magically. Once all vargouille fang damage has been healed nonmagically, the poison ends.
