Lava Slime

The Lava Slime is a Slime type monster that spawns in the underworld. It gives off an orange glow with fire particles.

Lava Slimes take no damage from lava and float on it like regular Slimes do on water, except that Lava Slimes bounce very high into the air on contact with lava, instead of gently bouncing up and down like normal slimes do in water. Lava Slimes also have increased jumping (and thus movement) compared to any other normal slime (excludes the King Slime)

Lava Slimes are immune to the Poisoned and the On Fire! debuffs.

Unlike other slimes, the Lava Slime does not drop the gel crafting material on death.
