The Overworld is the starting and main dimension in all of Minecraft. There are quite a few biomes in the Overworld, including Taiga, Snow, Hill, Plains, Jungle, Desert and Ocean. There are also a variety of mobs; the vanilla Zombie, Skeleton, Enderman, Spider Jockey, Spider, Cow, Pig, etc.
There are numerous DivineRPG mobs that spawn in the Overworld.
- Seven in caves...(Cave Crawler, Rotatick, Caveclops, The Eye, Enthralled Dramcryx, The Grue, Rainbour)
There are also mobs like the Kobblin, which spawn in several biomes.
Also found in the Overworld is the Pumpkin Spider, which only spawns near pumpkin patches.
Divine RPG does override the regular spawning mobs such as cows, but does not effect the spawning of villages, temples or biomes.
NOTE: the Wither is a vanilla Minecraft boss, and has not been modded.
