Salvage is an action similar to Destroy in that it removed built structures. However, where-as using Destroy all the materials used in that structure's construction are lost, with Salvage there is roughly a 50% chance of any material being returned to you. NOTE: This doesn't mean you get 50% of the construction materials, but rather each material which was built in has a 50% chance of being returned meaning it is possible to get less, OR more, than 50% of what was built in. You only Salvage structures you know how to build yourself and which are not Claimed by another pilgrim unless you have Waste Permissions. Salvaging structures ignores their Soak Value.
