Javelin of Lightning

Javelin+1: magic, zeus strike, thrown, piercing, 1d6
magic: counts as magical for purposes of damage reduction.
zeuz strike: once per dawn when thrown, it trans-
forms into a bolt of lightning, until it reaches the
target, turning back into a javelin. All creatures
in a 5' wide line between you and the target take
4d6 lightning damage, 13 Dex save for half.
