Blight Warden

Large aberration, neutral

A Blight Warden is a large Void creature that serves as a territorial guardian. Standing roughly eight feet tall, it resembles a hunched humanoid form composed of compressed grey matter: stone, earth, and organic material fused together by Void energy. Its surface shifts slowly, as if breathing. Two points of pale light serve as eyes, though it perceives primarily through tremorsense.

Traits

Void Aura. The Blight Warden projects a 15-foot radius aura of Void energy. Creatures other than Void creatures that start their turn in the aura take 2d6 cold damage. The aura can be temporarily suppressed with a DC 15 Arcana check (action, lasts 1 round).
Immovable Stance. The Blight Warden has advantage on saving throws against being pushed, pulled, or knocked prone.

Actions

Slam. *Melee Weapon Attack:* +6 to hit, reach 10 ft., one target. *Hit:* 13 (2d8 + 4) bludgeoning damage plus 7 (2d6) cold damage.
Void Pulse (Recharge 5-6). The Blight Warden's aura flares. Each creature within 30 feet must succeed on a DC 14 CON save or take 4d6 cold damage and be pushed 10 feet away from the Warden. On a success, half damage and no push.
