Exquisite Alloy Orb (High-Grade)

Although solid, this orb of metal swirls with bright silver and dark iron colors, as if made of liquid. When you activate the alloy orb, select cold iron or silver. The affixed weapon functions as the chosen material for 1 minute, suppressing its original material. Powerful weapons overwhelm the magic of this talisman, and it works only on weapons of 8th level or lower.
