On initiative count 20 (losing initiative ties), the fraz-urb’luu takes a lair action to cause one of the following effects; the same effect can’t be used two rounds in a row:
Fraz-Urb’luu causes up to 5 doors within the lair to be come 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 Difficulty 23 Will saving throw or take 33 (6d10) psychic damage.
The region containing the fraz-urb’luu's lair is warped by the fraz-urb’luu’s magic, which creates one or more of the following effects:
Intelligent creatures within 2 kilometers of the lair frequently see hallucinations of long-dead friends and comrades that vanish after only a brief glimpse.
Roads and paths within 10 kilometers 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 2 kilometers of the lair, that creature must succeed on a Difficulty 23 Will 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.
No concoctions, maneuvers, or spells
All creatures in this system should have maneuvers or spells. You should add some maneuvers or spells to this creature. If you do so, please make a suggestion on github so I can finish adding maneuvers and spells to all creatures via https://github.com/mlenser/kryx-rpg-issues/issues/9.
