Elemental Slimes

Elemental Slimes are like normal Slimes, except they've been magically imbued with elemental properties. A slime with a given element is both immune to it and deals that kind of damage. For example, a red slime would be immune to fire damage.

Elemental Slimes are a simple recoloring of the Slimes that already exist in Minecraft. Unlike regular Slimes that only spawn in certain chunks, however, Elemental Slimes are "global mobs." This means that unlike normal mobs, who are selected from 3-4 different possibilities assigned to the current Area, Elemental Slimes belong to a much larger set of mobs that appear infrequently, but everywhere in the world of Minecraftia
