Ecology

Stone-Eater Slime is a primitive life form thriving wherever there is moisture and decay — sewers, dungeons, deep caves. It is most often found in mountain regions. It is small-sized, which shapes how it hunts, hides, or fights.

Behaviour

Stone-Eater Slime is mindless hunger, drawn to motion and warmth, indifferent to consequence. Its alignment varies by individual or is irrelevant — it acts on instinct, drive, or whoever commands it. It is largely instinct-driven; complex strategy is the work of whoever (or whatever) commands it.

Origin

Stone-Eater Slime is introduced in Kobold Press's Tome of Beasts 3 (2022). Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
