Flesh House

A bhoga swarm normally inhabits a hollowed-out reconfigured corpse called a flesh mansion (with some variations to the name: a corpse of a smaller creature would become a flesh cabin, while a particularly large one can be a flesh fortress), which it uses as a shelter, vehicle, and war machine. When the swarm wears a flesh mansion, it uses the original creature's attacks and abilities. Unlike a normal swarm, the flesh mansion's attacks have reach and threaten an area within its reach. The flesh mansion's hit points are based on the size of the original creature. The flesh mansion gains immunity to poison, resistance 10 to acid, cold, electricity, and fire, and spell resistance equal to 11 + the original creature's HD.
