To obtain bones in Tribes of Midgard, you must first breed goblin enemies. You can only find these creatures in the Land of Pools biome. This biome is easy to identify by looking at the brown texture on the ground, you will know that you have reached it.
The game will also show you the name of the biome in the form of a pop-up message. If you still can’t find the Land of Pools biome, all you need to do is remember that this biome is usually the first area you find next to the Ash area. Once you pass the Bright Forest, the ash region will appear.
When you finally reach the biome area, you will encounter goblin enemies. Now you can breed these goblins in hideouts and camps throughout the biome. Once you breed these goblins, you can kill them to get small bones.
You can use these bones to make different recipes. If you don’t want to hunt down goblin enemies and breed them, there are other alternative methods you can try to obtain bones. You can find the skeleton remains in the smokey highland and glacial peaks biomes.
