Fungal Crawler (5e Creature)
From D&D Wiki
Medium aberration, chaotic evil
Spider Climb. The fungal crawler can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 6 (1d6 + 3) piercing damage.
Spores (Recharge 5-6). All creatures in a 15 ft. radius centered on the fungal crawler must attempt a DC 13 Constitution saving throw. On a failure, they take 11 (3d6) necrotic damage and become poisoned. On a success, they take half as much damage.
Born from the same source as trolls, fungal crawlers are born from human suffering. Fungal crawlers wander aimlessly, only attacking anything that comes too close. Fungal crawlers emit the sounds of their origin; the moans, wheezes, and gasps of pain and death, leading to many accidentally earning the ire of that creature by approaching to administer help.
