Each time you make an attack roll with this magic weapon and hit, you can have it deal Lightning damage instead of Piercing damage.
Lightning Bolt. When you throw this weapon at a target no farther than 120 feet, you can forgo the ranged attack roll and turn it into a bolt of lightning, forming a 5-foot-wide Line between you and the target. The target and every other creature in the Line except you makes a DC 13 Dexterity saving throw, taking 4d6 Lightning damage on a failure or half on a success. Immediately afterward, the weapon reappears in your hand. This property can’t be used again until the next dawn.
