Other sages maintained that gas spores had been purposefully created by beholder mages, while some believed that they had been created by mind flayers as a first line of defense, along with brown mold and shriekers. The origin of gas spores was not unanimously agreed upon, however. Gas spores were thought to have first appeared as a consequence of parasitic fungi feeding off the corpses of dead beholders and becoming infected with aberrant magic after a long period of adaptation, they acquired the ability to quickly sprout from any infected corpse. Gas spores hit in the rhyzome growths did not explode. Ī gas spore whose main body was hit by an attack immediately exploded, releasing poisonous gas and a large number of spores that reached a 20 feet (6.1 meters). Mind flayers were usually ignored by gas spores. The infestation killed the host within a day if left unchecked, after which several tiny gas spores emerged from the corpse, reaching maturity within seven days. The creature deposited its spores into the body of a warm-blooded and sufficiently large creature (the size of a gnome or larger) by merely touching the creature. Combat Īlthough harmless when feeding, the danger posed by a gas spore lay in its reproductive cycle.
An infected humanoid could then access fragments of those memories. Gas spores that grew upon the corpses of dead beholders were known to carry the memories of their host. Gas spores were hollow, but their interiors contained a large number of spores kept under high pressure. They were used to extract lichen and mold from walls, as well as leaves from trees and scum from the surface of ponds.
The rhyzome growths served as the feeding organs of the gas spore. In the absence of food, gas spores hibernated and could remain in that state for centuries. Communities of gas spores existed peacefully in locations where food was sufficiently abundant. Behavior īeing fungi, gas spores were non-intelligent creatures. The difference could only be noticed as one approached the gas spore. It had a central false eye and ten rhyzome growths on its top, which resembled a beholder's central eye and eyestalks. A gas spore was a spherical floating creature.
