This technique allows the user to repair one simple or moderate Large or smaller object made primarily of metal or rock. Doing so requires the user to make a int check DC equal to the item he seeks to repair. Every minute spent concentrating on the object mends it for 1 hit point. If the user does not have the Master-craft feat, the object has a 10% chance of losing its master-craft quality when being repaired. A failed Int check means that the chakra is spent, but the technique will not function properly.
