Enormous A mu spore is a massive creature and takes up a space of 10 squares by 10 squares (50 feet by 50 feet).

Spores (aura) 60 feet. A living creature that enters the area or ends its turn within it is corrupted by spores. It must succeed at a DC 42 Fortitude save or be clumsy 1, enfeebled 1, and slowed 1 for 1 round. Fungi and plants are immune.

Grasping Tendrils [free-action] Trigger A creature within 10 feet of the mu spore moves or attacks the mu spore. Effect The spore uses Grab on the triggering creature. There is no limit to how many creatures it can grab with the sticky tendrils that cover its body.

Speed 40 feet, fly 50 feet

Melee [one-action] jaws +40 (deadly 3d12, reach 30 feet), Damage 4d12+18 piercing plus Improved Grab

Melee [one-action] tentacle +40 (agile, reach 100 feet), Damage 4d10+18 bludgeoning plus Improved Grab

Cough Spores [two-actions] The mu spore releases a cloud of burrowing spores in a 400-foot cone. The spores deal 22d6 piercing damage to all creatures, objects, and wooden structures in the area, but not to plants or fungi (DC 46 basic Reflex save). The mu spore can’t use this ability again for 1d4 rounds.

Enormous Inhalation [two-actions] The mu spore pulls all creatures and objects in a 400-foot cone 400 feet toward its mouth. A successful DC 43 Fortitude save halves the distance, or avoids the pull on a critical success. The mu spore automatically attempts to Swallow Whole each creature adjacent to it at the end of the inhalation.

Fast Swallow [reaction] Trigger The mu spore Grabs a creature with its jaws. Effect The spore uses Swallow Whole.

Greater Constrict [one-action] 15 bludgeoning, DC 45

Overpowering Jaws The mu spore still deals 18 piercing damage if its jaws Strike is a failure (but not on a critical failure).

Swallow Whole [one-action] (attack) Gargantuan, 20d6+9 acid, Rupture 37


A mu spore is a thankfully rare fungoid monstrosity of vast power and strange intellect. Even the smallest mu spores are never less than a hundred feet long from tentacle tip to tentacle tip, yet despite this vast bulk, they are capable of flying with an uncommon grace, venting jets of foul-smelling spores to guide their flight.

Many societies tell tales of vast mu spores appearing over cities at the dawn of apocalyptic events, but they’re more than just ravenous eaters of nations. Mu spores often possess rare or esoteric knowledge, and if peaceful contact can be made, this lore can be quite valuable. Their spores can also be used to craft certain foul drugs or deadly alchemical poisons, but harvesting these ingredients is dangerous, as the spores are not viable for long once they’ve been shed, forcing alchemists seeking to harvest them to operate in perilously close proximity to the abominations.

Mu spores dwell in vast caverns, their pallid underbellies glowing softly to give the eerie impression of a strangely shaped ” moon,” adrift near the darkened ceiling so far above. Caverns can be faintly lit by this illumination-an unnerving sight for any traveler not expecting Light in such a lightless realm.
