Fungal Engine

COMPLEX HAZARD 19

Stealth +37 (legendary) to notice the fungi is potentially hazardous and that the two mushrooms in the middle are load bearing and that destroying those with damage can disable the hazard; noticing the engine itself has a DC of 0

Description A thick mass of pulsing fungi and mold infested with ghostly shapes cakes the walls of the room.

Disable DC 41 Nature seven times to seek out and remove seven specific nodes of fungi that govern the intake and dispersal of energy, or DC 47 Religion three times to exorcise the souls out of the engine and force it to shut down

AC 43; Fort +35, Ref +29

Hardness 32, HP 130 (BT 65); Immunities critical hits, precision

Psychic Shriek

Trigger any damage is inflicted on the engine, or any attempt to disable it critically fails

Effect The entire mass of fungi shudders, then emits a piercing psychic scream as the trapped souls within cry out. All non-fungi creatures in area E3 take 10d6 spirit damage (DC 41 basic Will save), and four vansidieth demons waiting for this precise alarm use translocate to teleport into the room to attack the intruders. The hazard then rolls initiative.

Routine

(1 action) The fungal engine expels clouds of toxic spores on its turn, causing all non-fungi and non-demon creatures in the room to take 10d6 poison damage (DC 41 basic Fortitude save); any creature that takes damage is exposed to grayshroud.
