Entropy's Shadow (aura, divine, necromancy, negative) 40 feet. Vanyvers leak entropy and corruption from their very being. A living creature entering or starting its turn in the aura takes 3d6 negative damage with a DC 30 basic Fortitude save. If it fails, it's also enfeebled 1 for 1 minute and pulled 10 feet toward the vanyver.

Sunlight Powerlessness A vanyver caught in sunlight is stunned 2 and clumsy 2.

Catching Bite [R] Trigger A creature within reach of the vanyver's jaws makes a melee Strike against the vanyver with a weapon; Effect The vanyver chooses to be hit. If the attack would've missed, it hits. The vanyver catches the weapon in their jaws and uses Drain Magic on it without fulfilling Drain Magic's requirements.

Drain Magic [>] Requirements The vanyver's last action was a successful jaws Strike against a creature, object, or spell effect; Effect The vanyver casts an innate dispel magic on the same target; if the target was a creature, the vanyver can target a spell affecting the creature instead. If a spell effect or item is successfully counteracted, the vanyver gains temporary Hit Points equal to double the counteract level of the effect that was counteracted.

Snatch The vanyver can Fly at half Speed while they have a creature grabbed or restrained in either or both of their talons, carrying that creature along with them.
