Universal Fragments are used to advance permanent artifacts. They are not a resource that can be transported on missions or used for traditional trade between players.
Universal Fragments are inventory items. They can come from several sources depending on active systems, including the shop, missions, exploration, or certain bonuses.
Each upgrade consumes Universal Fragments. An artifact cannot exceed level 10.
Example
If you have enough Universal Fragments, you can choose an artifact and start upgrading it. Its level then increases by +1, and its bonus becomes stronger.
