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 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) and Wisdom (Insight) checks have disadvantage, and all Charisma (Deception) and Charisma (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.
