Enhance Weapon

You flick droplets of water at the target creature's weapon and a metallic sheen coats it. You can make yourself the target of this spell before you attack on your turn. When you cast this spell, you choose to either make the target creature's weapon Adamantine or Silvered, which changes what material components you need to use.

Adamantine: Water from an underground spring.
Silvered: Melted snow from the top of a mountain.

Regardless of the concentration, you can cast this spell twice on the same weapon to grant it the benefits of both Adamantine and Silver weapons. When the spell ends, the weapon type returns to normal.
