Poisonous Mold

A creeping fungal bloom that thrives on rot and spilled blood, swelling outward to fill a room before bursting into a lethal haze.

Feed on Decay The mold expands when fed by blood or decay. If at any point a creature takes bleed damage while adjacent to the mold or a dying or dead body is adjacent to the mold, the mold grows to expand into every square adjacent to its current space. This can happen only once per day.

Spore Burst [Reaction] (poison) Frequency once per day.

Reset Unless entirely eradicated (typically with acid or fire), the mold regrows over the course of 2 weeks.
