Muck Eater

Wondrous item, legendary (requires attunement)

This copper bullseye lantern is in the shape of a fat, laughing toad. The light that comes from its gaping mouth is tinged green.

While attuned to Muck Eater, you are immune to the damage or effects of hazards with “slime”, “mold”, “fungus”, or “ooze” in their names. Additionally, while lit, Muck Eater burns for 6 hours on 1 pint of oil, shedding bright light in a 60-foot radius and dim light for an additional 60 feet. Oozes cannot enter into the light of Muck Eater and any ooze that begins its turn in the light may only take the Dash action to try to escape its radius.

Feast. As an action, you may force a target ooze that you can see to make a DC 16 Constitution saving throw. On a failure, that creature is destroyed. Once used, this property cannot be used again until dawn.
