Black Slime

The Black Slime only spawns in the Cavern layer. Black Slime attacks have a chance to cause Darkness, which decreases radius that light sources will illuminate, making it more difficult to see.

Similarly to Mother and Baby Slimes, the Black Slime blends slightly with the background of the Cavern layer, making it difficult to detect. As such, it can often catch players off-guard.

Like all slimes, they drop some Gel and Coins.
