magic item from DMG, DnD5e
This javelin is a magic weapon. When you hurl it and
speak its command word, it transforms into a bolt of
lightning, forming a line 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. 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 damage.
The javelin's property can't be used again until the
next dawn. In the meantime, the javelin can still be used
as a magic weapon.
