Thick black mud churns upward, knitting with coiling green vines and splintered, slime-draped logs into a towering, dripping bulk. Yellowed reeds jut like broken ribs; fetid gas hisses from ruptured bladders of rot, while rope-thick tendrils lash out, slick and barbed.
Swamp horrors are magically awakened masses of muck and vegetation—mostly vines, logs, and rotting bushes—created by malevolent fey to do their bidding. They can create noxious clouds of gas around them and then entangle creatures with their vines before pounding them into pulp.
