Fey-Touched Blade 2014

You touch a nonmagical weapon and imbue it with the magic of the fey. Choose one of the following damage types: force, psychic, necrotic, or radiant. Until the spell ends, the weapon becomes a magic weapon and deals an extra 1d4 damage of the chosen type to any target it hits.

When you cast this spell using a spell slot of 3rd level or higher, you can imbue one additional weapon for each slot level above 2nd.
