The Mother Slime is a type of slime that starts spawning when you reach the Cavern layer. They spawn 1-3 Baby Slimes upon death, and like all Slimes, drop Gel and sometimes coins. It is one of the largest ordinary slimes in the game, only topped by King Slime and the Rainbow Slime.

Mother Slimes are immune to the Poisoned debuff.

Just like many other slimes, Mother Slimes become passive around the player when they have the Royal Gel accessory equipped.

Notes[edit | edit source]

Similarly to Baby Slimes and Black Slimes, the Mother Slime blends slightly with the background of the Cavern layer, making it difficult to detect. As such, it can often catch players off-guard.
Explosive weapons, especially Grenades, work well when fighting the Mother Slime. The explosion will almost certainly damage/kill the baby slimes it spawns upon death.
Once Hardmode begins, the spawn rate of Mother Slimes will drop drastically; they will usually fail to spawn at all.
