Canoloth

Canoloths are yugoloths fiends who are frequently employed as contracted guardians. They diligently fulfill their part, not exceeding it one iota.

Description
Canoloths are fiendish trackers and guardians employed by individuals of evil intensions. They prefer to enter into contracts to guard valuable treasures and important locations, always doing exactly as asked — never any more, never any less. Unless instructed to kill, a canoloth merely holds on to its prisoner.

Appearance
Canoloths are large, bulldog-shaped creature with armor plating embedded in its hairless skin. Its circular mouth is filled with a row of teeth surrounding an exceptionally long, tendril-like tongue.

Abilities
Canoloths are resistant to cold, fire, lightning damage and to bludgeoning, piercing, and slashing damage from nonmagical weapons. They are also immune to acid and poison damage, as well possessing an immunity to the poisoned condition.


 * Dimensional Lock: Other creatures can't teleport to or from a space within 60 feet of the canoloth . Any attempt to do so is wasted.
 * Magic Resistance: The canoloth has advantage on saving throws against spells and other magical effects.
 * Uncanny Senses: The canoloth can 't be surprised unless it's incapacitated.

History
In the Genesis ward of Aeor, the Mighty Nein encountered one aeorian nullifier who was joined by a creature described as a canoloth. Until it could even realize itself, the canoloth was banished by Caduceus, and then hastily avoided by the group.
