Fraz-Urb’luu
Source: Mordenkainen Presents: Monsters of the Multiverse p. 129

Fraz-Urb’luu is the Prince of Deception and Demon Lord of Illusions. He uses every trick, every ounce of demonic cunning, to manipulate his enemies—mortal and Fiend alike—to do his will. Fraz-Urb’luu can create dreamlands and mind-bending fantasies able to deceive the most discerning foes.
Once imprisoned for centuries below Castle Greyhawk on the world of Oerth, Fraz-Urb’luu has slowly rebuilt his power in the Abyss. He seeks the pieces of the legendary staff of power taken from him by those who imprisoned him and commands his servants to do likewise.
The Prince of Deception’s true form is like that of a great gargoyle, some 12 feet tall, with an extended, muscular neck; a smiling face framed by long, pointed ears and lank, dark hair; and bat-like wings are furled against his powerful shoulders. He can assume other forms, however, from the hideous to the beautiful.
Many of the cultists of Fraz-Urb’luu aren’t even aware they serve the Prince of Deception, believing their master is a beneficent being and granter of wishes, some lost god or Celestial, or even another Fiend. Fraz-Urb’luu wears all these masks and more. He particularly delights in aiding demon-hunters against his demonic adversaries, driving the hunters to greater and greater atrocities in the name of their cause, only to eventually reveal his true nature and claim their souls as his own.

Fraz-Urb’luu’s Lair
Fraz-Urb’luu’s lair lies within the abyssal realm of Hollow’s Heart, a plain of white dust with few structures on it. The lair itself is the city of Zoragmelok, a circular fortress surrounded by adamantine walls topped with razors and hooks. Corkscrew towers loom above twisted domes and vast amphitheaters, forming a surreal and disorienting cityscape.
The challenge rating of Fraz-Urb’luu is 24 (62,000 XP) when he’s encountered in his lair.

## Lair Actions
On initiative count 20 (losing initiative ties), Fraz-Urb'luu can take one of the following lair actions when in his lair; he can't take the same lair action two rounds in a row:
- **Conjure Walls and Doors.** Fraz-Urb'luu causes up to five doors within the lair to become walls and an equal number of doors to appear on walls where there previously were none.
- **Psychic Anguish.** Fraz-Urb'luu creates a wave of anguish. Each creature he can see within the lair must succeed on a DC 23 Wisdom saving throw or take 33 (`6d10`) psychic damage.
- **Simulacrum.** Fraz-Urb'luu chooses one Humanoid within the lair and instantly creates a simulacrum of that creature (as if created with the [simulacrum](Mechanics/CLI/spells/simulacrum-xphb.md) spell). This simulacrum obeys Fraz-Urb'luu's commands and is destroyed on the next initiative count 20.
## Regional Effects
The region containing Fraz-Urb'luu's lair is warped by his magic, creating one or more of the following effects:
- **Beguiling Realm.** Within 6 miles of the lair, all Charisma ([Persuasion](Mechanics/CLI/rules/skills.md#Persuasion)) and Wisdom ([Insight](Mechanics/CLI/rules/skills.md#Insight)) checks have disadvantage, and all Charisma ([Deception](Mechanics/CLI/rules/skills.md#Deception)) and Charisma ([Performance](Mechanics/CLI/rules/skills.md#Performance)) checks have advantage.
- **Nostalgic Pangs.** Sapient creatures within 1 mile of the lair frequently see hallucinations of long-dead friends and comrades that vanish after only a brief glimpse.
- **Twisted Paths.** Roads and paths within 6 miles of the lair twist and turn back on themselves, making navigation in the area exceedingly difficult.
If Fraz-Urb'luu dies, these effects fade over the course of `1d10` days.
