Dungeon Slime

The Dungeon Slime is an enemy found in the Dungeon. It is an indigo-colored slime with a Golden Key inside. It always drops the Golden Key when defeated. Unlike most other slimes, it does not drop Gel. It can spawn anywhere in the dungeon, but appears less frequently than other Dungeon enemies. Dungeon Slimes are immune to the Poisoned debuff.
