Arcane Weapon

You touch a weapon and imbue it with magic. If the weapon isn’t magical, it becomes a magic weapon for the spell’s duration. Until the spell ends you add an additional d6 damage of the chosen weapon's primary type whenever you hit a target with an attack using that weapon.

At Higher Levels: If you cast this spell at 2nd level or higher, you can target one additional weapon for each slot level above 1st.
