While doing some repairs it just happened to hit me. If any class should be able to repair Organic its clerics. Being organic one would be able to heal the object, so why not allow the healing spells to have that affect on organic material. Cure light could have like a 5 percent chance or so of repairing 1 condission of damage, and so on for other spells. Basicly the more mp you dump into fixing it the more its healed or repaired. Could even go as far as different substances being repairable by different classes. Nature based products can only be done by druids and rangers, flesh types or so on by clerics and paladins.
