Biomantic Polyhedroozes

When Dr. Francis Norman Stein left his lab at short notice (following a pitchfork-wielding-mob related event), he left an entire pool of his patent-pending Mut-X exposed to the elements. Things fell into it; those things had brains, and those brains, their memories, and the sum of their intelligence fused with gelatinous cubes into biomantic polyhedroozes.   Empathetic. When a biomantic polyhedrooze forms, it begins absorbing the latent psychic energy of its environs. Creatures with strong psyches that are nearby in either space or time influence the nascent sentience of the polyhedrooze. A long-destroyed lich might impart its madness and hate into the ooze, whilst a colony of highly-charismatic mice might lend the goopey mass a penchant for cheese.   Reactive Mutations. The true feat of Dr. Stein’s research, and a trait that the polyhedroozes embody, is that of extreme biomantic reaction to environmental stimuli. A polyhedrooze that takes damage immediately adapts its morphology to prevent further damage of that type. The larger the polyhedrooze, the more such adaptations it can sustain at any one time.   Size Matters. Bigger polyhedroozes have absorbed more brains and, so, are more clever. A polyhedrooze that reaches a critical mass might decide to split into two, with the idea of sending one of its halves in search of pastures new. Unfortunately, the decrease in intelligence that results from a split means that polyhedroozes can get confused and end up in a cycle of splitting and reforming over and over.   During the events of Session 001 - Polyhedrooze, a group of monster hunters entered into The Big Bad Base and killed all known biomantic polyhedroozes. They are currently considered extinct.
