    • Innate Spellcasting. The xethiloth’s innate spellcasting ability is Charisma (spell save DC 18, +10 to hit with spell attacks). It can innately cast the following spells, requiring no material components:


      • Multiattack. The xethiloth makes two attacks, one of which can be Invocation of the Ibshalek.
      • Claw. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 17 (3d8 + 4) slashing damage plus 10 (3d6) necrotic damage, and the target must make a DC 18 Constitution saving throw or gain a level of exhaustion.
      • Necrotic Lash. Ranged Spell Attack: +9 to hit, range 60 ft., one target. Hit: 31 (6d8 + 4) necrotic damage.
      • Invocation of the Ibshalek (Recharge 5-6). The xethiloth calls forth the power of their unholy patron. Non-yugoloth creatures within 30 feet must make a DC 18 Wisdom saving throw, taking 35 (10d6) necrotic damage and becoming frightened on a failed save or taking half as much damage and suffering no additional effects on a successful one.


This tall figure’s form is hidden beneath elaborate layers of vestments, silken veils, and a shroud of darkness and shifting distortion. It gestures with two hands while a pair of grasping tentacles hold wands or symbols of station. Their face masked from sight, the symbol of their chosen Ibshalek hovers over their veiled head.

Xethiloths are yugoloth priests who insure that the transformative arc of these fiends stays true.

Priests of the Unholy. Xethiloths serve as the yugoloth priestly caste, agents of the Ibshalek, though there are yet other and more highly exalted religious stations. They oversee yugoloth religious rites, determine a lowercaste yugoloth’s fitness to ascend to a higher form, and enact the actual transformative rituals that allow such.

Veiled Majesty. Perpetually cloaked by obfuscating robes, veils, and illusions, xethiloths?f true appearance is unknown.

Observed differences in their cloaked forms suggest a myriad of true forms, varying by Ibshalek served, or otherwise suggest a shapeshifting ability.

Reclusive Masters. Xethiloths are rarely seen by non-yugoloths, usually only when they are present to speak on behalf of one of the Ibshalek or as a threat and display of yugoloth power. Cloistered in their masters?f realms, they seem to be nowhere yet simultaneously omnipresent among their flock, aware of any miniscule transgression or failure.

Corrosive Promises

Held aloft on skeletal wings, draped in black and purple silks, the creature wears a crown of swirling soul gems from which it periodically feeds-a grand connoisseur of agony. Six arms, two humanoid and four skeletal, hold arcane accouterments. Her jackal head is partially stripped of putrefying flesh while her reptilian tail ends in a swirling globe of sickly yellow light, like a dangling lure of some deep-sea predator.
