Must weapons and Armor made out of Special Materials be Masterwork?

[GamerDJ]

Well the question is the thread name. I'm always thought that all weapons or armor made out of special materials had to be master work. Most of the material given in the Players handbook state that they must be masterwork because of the cost. I would also think that because your working with a rare or hard to use material they had to be made at high quality.

No, not all special material require masterwork quality. Most do, and note so in their descriptions (usually incorporating the price for masterwork in the price for the material), but a few don't.

From the CRB, neither cold iron nor silver require the item to be masterwork.

Expanding the list of special materials that don't require masterwork frum UE are: blood crystal, cold iron, Elysian Bronze, griffon mane, living steel, viridium, whipwood, wyroot, as well as the primitive materials.

The one that is mostly in question is Crystalline special marterial, It's from the Underdark Adventure guide. (Which is third party)
