Mending Wheel

The Mending Wheel or Wheel of Mending is one of the artifacts Tiberius was looking for and eventually found before the Stream. It allows the user to repair damaged magical items and gems.

Tiberius acquired the wheel when he and the party fell into an ancient cistern within Emon and were attempting to find their way out. They ended up discovering the ruins of a city where a hag was living. In exchange for a part of Tiberius's luck, she traded him the wheel. She showed them the way out and back to the surface after they slayed an umberhult, an encounter where Grog almost died.
