[RPG] Can a weapon be both adamantine and silvered

dnd-5especial-materialsweapons

Xanathar's Guide to Everything adds an option to have a weapon made of or coated with adamantine for an additional 500 GP above the weapon's base price (XGtE, 78). How does this interact with the Player's Handbook option of having a weapon coated with silver for an additional 100 GP above the weapon's base price (PHB, 148)?

Can a weapon be both adamantine and silvered?

Best Answer

Yes. A weapon can be made of adamantine, but coated with silver.

The description of silvered weapons notes that the price includes not only attaching silver to the weapon, but doing so in a way that does not reduce its effectiveness. Therefore, if you silver an adamantine weapon (nothing in the description of silver limits it to steel weapons, so technically you can even silver a wooden weapon), it still retains the benefit of being adamantine.
