Javelin of Lightning

Transforms into a bolt of lightning 5 feet
wide that extends out from you to a target within 120 feet. Each creature in the line excluding you and the target must make a
DC 13 Dexterity saving throw, taking 4d6 lightning damage on a failed save, and half as much damage on a successful one. On a hit,
the target takes damage from the javelin plus
4d6 lightning damage.
