Lair actions

On Initiative count 20 (losing initiative ties), Fraz-Urb'luu can take a lair action to cause one of the following effects; he can't use the same effect two rounds in a row:

• Fraz-Urb'luu causes up to 5 doors within the lair to become walls, and an equal number of doors to appear on walls where there previously were none.
• 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.
• 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.

Regional effects

The region containing Fraz-Urb'luu's lair is warped by his magic, creating one or more of the following effects:

• Intelligent creatures within 1 mile of the lair frequently see hallucinations of long-dead friends and comrades that vanish after only a brief glimpse.
• Roads and paths within 6 miles of the lair twist and turn back on themselves, making navigation in the area exceedingly difficult.
• If a humanoid spends at least 1 hour within 1 mile of the lair, that creature must succeed on a DC 23 Wisdom saving throw or descend into a madness determined by the Madness of Fraz-Urb'luu table. A creature that succeeds on this saving throw can't be affected by this regional effect again for 24 hours.

If Fraz-Urb'luu dies, these effects fade over the course of 1d10 days.

Madness of Fraz-Urb'luu

If a creature goes mad in Fraz-Urb'luu's lair or within line of sight of the demon lord, roll on the Madness of Fraz-Urb'luu table to determine the nature of the madness, which is a character flaw that lasts until cured. See the 8 for more on madness.

21–40	"I have intermittent hallucinations and fits of catatonia."
41–60	"My mind wanders as I have elaborate fantasies that have no bearing on reality. When I return my focus to the world, I have a hard time remembering that it was just a daydream."
61–80	"I convince myself that things are true, even in the face of overwhelming evidence to the contrary."
81–00	"My perception of reality doesn't match anyone else's. It makes me prone to violent delusions that make no sense to anyone else."
