Biome Goblin

A Biome Goblin or Instance World Goblin was a goblin that did spawn in STW worlds every so often. These goblins were linked to the biome they spawned in e.g. Crimson Goblin, Forest Goblin etc. When they were killed they would create a small world portal to a Goblin Instance World.

These worlds were used for mining shards of ores or for gathering building materials, as well as often having chests which have furniture items stored inside them. These shards were changed into ores when the player left the instance. Two shards were equivalent to one ore.

When the player leaft those worlds for a certain amount of time and/or goes a certain distance away from them the portal would close and wipe the temporary world from existence.
