Javelin of Lightning

•Thrown, transforms into a bolt of lightning, 5'
wide to 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, half on success.
•The lightning bolt turns back into a javelin when
it reaches the target. Make a ranged weapon attack
against the target. On a hit, the target takes damage
from the javelin plus 4d6 lightning
•Can't be used again until next dawn.
