The repair skill is an important skill in the game for long term survival. Repair skill starts out at 50 and can be increased by repairing items. The higher your repair skill, plus the quality of the repair tools used, the higher the chance at a successful repair. If the item fails to repair, the items used in the repair are consumed. Repair amount depends on current repair level, and the item itself. For example, the amount of condition improved may be 30% on a hunting knife, whereas wool socks might get 50% for a successful repair.
