Combining weapon material question-

[Selvaxri]

Simple question- can i make a Mithral or Adamantine weapon with the Fire-Forged quality?

I assume that by 'Fire-Forged' you are referring to the Fire-Forged Steel material. If so, the answer is no.

From the CRB: "If you make a suit of armor or weapon out of more than one special material, you get the benefit of only the most prevalent material."
