Babau

Babaus are skeletal demons wrapped in tight leather skin and marked with a single, long horn-like growth that curved out from the back of their skulls.

Appearance
Babaus are a lithe, humanoid-looking demons with elongate, clawed limbs and long, thin tails. They have black, leathery skin wrapped tightly about their bodies. The back of their heads are elongated, curving into a single horn, and their expressions are dark and skeletal, with sharp teeth and dark tongues. They have pupil-less, yellow eyes.

Abilities
Babaus are immune to poison damage and can not be poisoned. They are also resistant to cold, fire, lightning damage; and bludgeoning, piercing and slashing damage from nonmagical attacks.

Babaus possess innate spellcasting abillities (Wisdom spell save DC 11) and can at will cast the fololowing spells, requiring no material components: Darkness, Dispel Magic, Fear, Heat Metal, Levitate.

Their Weakening Gaze targets one creature that it can see within 20 feet of it. The target must make a DC: 13 Constitution saving throw. On a failed save, the target deals only half damage with weapon attacks that use Strength for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

History
The Mighty Nein fought three babaus in the stone giant fortress of Braan. These demons arrived through a portal created by an abyssal anchor, and had previously killed many of the stone giants of Soorna's tribe.
