Vargouille
CREATURE 2Vargouilles are scavengers from the swamps of Abaddon, where they flop and flap through strange and haunted skies in constant search of fresh souls to torment. In this daemonic nightmare realm, vargouilles play a role similar to that of a raven or vulture, although they augment these roles with a malevolent delight in causing pain and anguish that no scavenger bird could ever hope to match. A vargouille is larger than a human head, typically between 12 and 20 inches high with a 15- to 35-inch wingspan. While vargouilles aren't natives of the Material Plane, they can be found there nevertheless, occupying graveyards, ancient battlefields, or anywhere one can find remnants of death and decay.
A creature who takes poison damage from a vargouille must succeed at a DC 18 Fortitude save or be cursed. The cursed creature can't regain HP except via magic, and anyone Casting a Spell to heal the creature must succeed at a DC 18 counteract check or the healing has no effect. The vargouille's counteract rank is equal to its creature level. A creature can attempt a new DC 18 Fortitude save once per day (typically when it makes its daily preparations) to end this curse. The curse ends automatically if the creature is healed to maximum HP.
The vargouille distends its jaw awfully and emits an unnerving shriek. All creatures within 60 feet who can see and hear the vargouille must attempt a DC 15 Fortitude save.
Success The creature is unaffected and is temporarily immune to Vargouille's Shriek for 24 hours.
Failure The creature is Paralyzed until the end of its next turn.
Critical Failure The creature is paralyzed. It can attempt a new save at the end of each of its turns, and the DC cumulatively decreases by 1 on each such save.
