Latch On. The udug latches on to a victim and does double damage to that person. They can also tell where the individual is within 1 mile of him or her. The victim constantly has one level of exhaustion.
Hard To See. The udug's ability to absorb light, and hide in darkness gives their opponents disadvantage to hit them.

Actions

Cause Sickness. Melee Weapon Attack +10 to hit, reach 5 ft, one target. Hit 20 1d12+8 psychic damage. The creature hit must also make a DC 15 Constitution saving throw or become ill leading to one level of exhaustion. Only an exorcism, a Wish spell, or Cure Disease spell can break this. On a success, the victim takes the psychic damage and nothing else happens.

Udug (or Utukku in Akkadian) are spirits / demons in Mesopotamia. Primarily evil, they are usually minor creatures of darkness. A few are good, and called upon to help with Mesopotamian exorcisms. They have a black body that sucks in all light with no visible features. They cause physical & mental damage when they latch on and attack a victim.

Suggested Environments

The old Mesopotamian region in Persia.
