Nightmare Portal
Level 16Hazard (Complex)Abilities
Trigger At the start of a round after a creature who can dream and isn't immune to sleep effects enters the room, the portal starts to glow with purple mist. At this point, the portal triggers as soon as such a creature looks into it. A character who just passes by and doesn't specifically avert their gaze must attempt a DC 11 flat to not accidently glance into the portal, while a character who Searches this room automatically looks into it unless they specify otherwise. Effect The nightmare portal casts Phantasmal Calamity (heightened to 8th level, DC 37 will), making reality appear to crumble away to reveal a vast cavern filled with bones through which immense wormlike creatures burrow as they endlessly eat away at the world. The trap then rolls initiative.
Description
Horrific visions of a lumbering monstrosity whose face is nothing but a fanged mouth lurch out of the violet mist to attempt to eat the viewer alive.
