Raw Materials are a group of items used as supplies in crafting weapons, armor, shields, and other accessories. Most melee weapons and armor can be made or purchased in a variety of materials. The material an item is made of affects its durability, weight, and effectiveness in serving its intended purpose.
Crafting a piece of equipment consumes an amount of the raw material used to create it. Some materials are available in several forms, some can be found in nature, while others must be bought from manufacturers.
When an item made with raw materials breaks, sometimes you may be able to salvage and reclaim some of the material from it in order to craft a new item. Use the Salvage action to reclaim materials from destroyed items. The GM decides how many units of reclaimed material you obtain, based on the circumstances in which the item was destroyed and the outcome of your check.
