Rudolph Slimes can be found in the Nivalis area, where they defend their Santa Slime masters. They are so-called due to their antlers on their heads. Unfortunately their antlers rot away as quickly as they do, and they are never left to be picked up. They are also scavengers though, so they may have picked up an item or two in their travels. Be warned though, that if you kill the Santa Slime boss, you kill this Rudolph Slime, and lose all of it's drops.
