Add a new rule called “Salvage” and give it the following text

If an item that an Orc holds has a crafting cost, the Orc that holds that item can Salvage that item to gain X resources. X is half the resources required to craft that item rounded down. Salvaging an item removes it from that Orc’s inventory. Any effects that would occur as a result of removing an item from an Orc’s inventory cannot occur as a result of salvage. For example, a Potion of Strength would not raise strength when salvaged. Equipped Weapons can’t be salvaged.
