The Uhm Stone is one of the most powerful things in Spineworld.
The Uhm Stone has a tiny splinter of the Monolith inside that has power to unlock things or power to run machines. It can be found in the Uhm Cave during Missions.
- Uhm Stones have related rocks, called Lesser Uhm Stones. These are smaller than Uhm Stones and more common to find.
