This strange type of fungus colony takes its name from its initial purpose: the wizard who first developed it sought a means to keep her tower clean from residue both mundane and magical. Wizard sponge does just that, dutifully cleaning its vicinity by devouring dust, organic debris, and even the decaying bodies of fallen creatures. Its designer intentionally crafted the fungus to not merely resist but be healed by fire, intended as an additional safety feature, and most varieties have a conveni

Abilities

Tremorsense 60 feet — Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.
Fire Healing — Anytime a wizard sponge would take fire damage, it instead regains 1d8 healing Hit Points (regardless of the amount of damage the fire effect would have caused).
Suction — Wizard sponges can climb on ceilings and other inverted surfaces.
Swarming Slither — The wizard sponge slithers over each creature in its space, dealing 2d10 acid damage (DC 20 Reflex save). A creature that critically fails is Sickened 1.
Weak Acid — Wizard sponge acid damages only organic material—not metal, stone, or other inorganic substances.

WORKS WELL WITH

AnvilLAND / AQUATIC / VERTICALAnvil locks enemies in position so the swarm can occupy their space and maximize area damage through positioning.
SnareLAND / AQUATIC / VERTICALSnare pulls scattered foes together, condensing them into the swarm's space for compounded area pressure through numbers.
WeaverLAND / AQUATIC / VERTICALWeaver slows or debuffs enemy Reflex saves, amplifying the swarm's area damage through tempo advantage.

PUNISHES

✖ clumping✖ precision reliance✖ fire reliance
stacking swarms compounds area-damage weakness against parties with splash or area effects
