Ur-Geist

Eater of Ontologies. So suffused with the primal anger of those killed in the sundering Is the Ur-Geist that they devour any hope of divine power. Whilst within 60 feet of an Ur-Geist creatures cannot regain health by magical means and instead gain temporary hit points equal to the amount healed- as the healing energy scabs over wounds forming squamous masses of radiancy.

Defy Magic. when targeted with a magical attack or magical weapon the Ur-Geist pulses a terrible rotting aura dealing 6 (3d4) necrotic damage to creatures within 30 feet of the creature.

Transubstantiating touch. wrought with the flesh of the damned when a piece of metal or wood touches an Ur-Geist it turns into a verdigris laden bronze. This dramatically increases the weight of an object and if a creature is holding an effected object they must make a DC 12 strength check to drop the object or fall prone.

Crushing Bulk. Melee Weapon Attack: +8 to hit, reach 10 ft., 10 foot cone, Hit: 17(3d10 + 4) Bludgeoning damage. When the Ur-geist hits using this attack against a creature with temporary hitpoints it deals an additional 15 points of necrotic damage.

Charnel Words. the Ur-Geist invokes a terrible word, that of its last babbled incoherency- creatures within 10 feet of the Ur-geist must make a DC 15 wisdom saving throw or temporarily lose the ability to speak common and take 20 psychic damage.
