Alkilith

D&D 2024 monster: Alkilith. Source: Mordenkainen's Tome of Foes. challenge rating 11, creature type Fiend (Demon), Medium size, speed 40 ft. Alkilith An alkilith is easily mistaken for some kind of foul fungal growth that appears on doorways, windows, and other portals. These dripping infestations conceal the demonic nature of the alkilith, making what should be a dire warning appear strange but otherwise innocuous. Wherever alkiliths take root, they weaken the fabric of reality, creating a portal through which even nastier demons can invade. Symptoms of Doom The appearance of an alkilith in the world heralds a great wrongness and an imminent catastrophe. An alkilith searches for an aperture such as a window or a door around which it can take root, stretching its body around the opening and anchoring itself with a sticky secretion. If left undisturbed, the opening becomes attuned to the Abyss and eventually becomes a portal to that plane (see "Planar Portals" in chapter 2 of the Dungeon Master's Guide). Spawn of Juiblex Alkiliths spring from the cast-off bits of Juiblex's hideous, shuddering body, then gradually become self-aware and set out to find their way onto the Material Plane. Since most cultists consider them too risky for summoning-they can, after all, create portals to the Abyss-alkiliths must find other escape routes out of their native plane.
