To repair an artifact, you will need to see an NPC Smith. As durability loss has recently been removed from these items, once repaired at a smith all artifacts will be reset to full durability and will no longer lose durability. Please note that when repairing an artifact for the first time, durability loss will figure into the initial cost as well as the condition. Artifact condition loss will still occur, and a significantly greater cost will be charged. With these changes to durability, artifacts can no longer be repaired by players and repairing artifacts at player houses will no longer provide the house discount.
