A souvenir that Scelerus took from the Silver City, Anubiek is the name the Indarians gave to the neothelid that serves as the illithilich's living phylactery.

Creature Sense (1 mile, Int 4 or higher).

Magic Resistance.

Living Phylactery.

Gibbering Souls: Anubiek constantly emits a miasma of psychic detritus formed from the countless souls it has devoured. Whenever a creature starts its turn within 120 feet of Anubiek, it must make a DC 16 Wis save. On a failed save, it can't take reactions until the start of its next turn and rolls a d8 on its turn to determine what it does. 1-4: it does nothing. 5-6: no action or bonus action, and it moves in a random direction. 7-8: melee attack against a random creature, or nothing.

Soul Release: Whenever Anubiek takes 15 or more damage on a single turn, a fragment of a devoured soul is released in the form of a specter, The specter has its own Initiative, serves Anubiek, and is reabsorbed in 1 hour unless it is destroyed.

Actions

Tentacles: +13 hit, 15 ft. reach, 3d8+8 bludgeoning damage plus 3d8 psychic damage. Large or smaller creatures must make a DC 18 Str save or be swallowed (10d6 force damage at the start of Anubiek's turns). If Anubiek takes 30 or more damage from a swallowed creature in a single turn, it must make a DC 18 Con save or regurgitate all swallowed creatures, which land prone within 10 feet of it. If a creature dies while swallowed, it is devoured body and soul by the living phylactery.

Force Breath (recharge 5-6): 60-foot cone. DC 18 Con save. 10d6 force damage on a failed save, half on a success.
