Mending

The Mend spell appears in Ultima Underworld II and enables the casting mage to restore a particular item to its original condition, be it damaged or depleted.

A successful invocation upon battle-worn weapons and armour will return them to immaculate form—much like the Repair skill—while refillable items such as lanterns will be replenished to their full capacity, in such a case circumventing the need for a supply of oil.
