House That Hunts

A demirealm dwelling whose windows blink, whose doors breathe, and whose rooms rearrange to digest whoever steps inside. It plays the patient host at first, letting the party wander deeper in. Then the hallways shift, scattering everyone into separate rooms, and the walls themselves begin to bite.

Room Bite: bludgeoning, 20 ft, +6 to hit, 3d10+6 as walls, floors, or doors slam shut. Hallway Shift: all creatures inside save Wis Mind or become separated into adjacent rooms, cooldown 3 rounds.

Living Architecture: immune to poison, disease, charm, fear, and prone. While rooted to its demirealm, it regenerates 5 hp each round unless damaged by fire, radiant, or a named key from its history. Senses: Night Vision (60 ft).
