Exotic Materials

Every exotic material has a unique Natural Property that defines how it reacts to its environment. This property remains true no matter what form the material takes, whether it's in its natural state or crafted into an item. If necessary, the description for each material lists additional properties given to weapons or armor constructed of that material. Some materials also have special crafting properties.

Most crafted items, such as tools or structures, require an amount of the material equal to their weight. Weapons and armor always require 10 lbs of the material (half for light weapons). The cost of a crafted item, such as a set of adamantine armor, includes both the cost of the materials and the workmanship necessary to create it. To determine the cost, first determine the cost of the raw material in pounds, and multiply it by the amount required. Second, multiply the cost by two to include the cost of the labour involved. Third, add the regular cost of the item in question. For example, a suit of adamantine plate armor costs 2000gp. (250gp for the adamantine required, 250gp for the cost of working the adamantium, and 1500gp for the cost of creating plate armor.)
Items can only be made from materials similar to their common form. For example, a sword can't be made of fabric, and hide armor can't be made of metal.
