Chapter 11: Crafting & Treasure / Materials

Precious Materials

Source Core Rulebook pg. 577 2.0
Materials with the precious trait can be substituted for base materials. For example, a hammer’s head could be made of adamantine instead of iron. Items made of a precious material cost more than typical items; not only does precious material cost more, but the crafter must invest more time working with it. In addition, more powerful items require precious materials of greater purity. A number of precious materials are described below. The Price entry for each material gives the Price of a simple non-magical item made of that material, based on its Bulk (if the item is lighter than 1 Bulk, use the price for 1 Bulk), as well as Prices for different amounts of the material itself. Prices for armor, shields, and weapons made of precious material are in the Armor (page 555), Shields (page 586), and Weapons (page 599) sections of this chapter.

Crafting with Precious Materials

Source Core Rulebook pg. 578 2.0
Only an expert crafter can create a low-grade item, only a master can create a standard-grade item, and only a legendary crafter can create a high-grade item. In addition, to Craft with a precious material, your character level must be equal to or greater than that of the material.

Low-grade items can be used in the creation of magic items of up to 8th level, and they can hold runes of up to 8th level. Standard-grade items can be used to create magic items of up to 15th level and can hold runes of up to 15th level. High-grade items use the purest form of the precious material, and can be used to Craft magic items of any level holding any runes. Using purer forms of common materials is so relatively inexpensive that the Price is included in any magic item.

When you Craft an item that incorporates a precious material, your initial raw materials for the item must include that material; at least 10% of the investment must be of the material for low-grade, at least 25% for standard-grade, and all of it for high-grade. For instance, a low-grade silver object of 1 Bulk costs 20 gp. Of the 10 gp of raw materials you provide when you start to Craft the item, at least 1 gp must be silver. The raw materials you spend to complete the item don’t have to consist of the precious material, though the GM might rule otherwise in certain cases.

After creating an item with a precious material, you can use Craft to improve its grade, paying the Price difference and providing a sufficient amount of the precious material.
