Charged Missle

One arrow, bolt, sling bullet, javelin, or spear you touch becomes infused with electrical energy. A successful ranged attack with the affected ammunition does its normal damage plus 5d6 lightning damage. The spell ends after the projectile is used, whether it hits or misses.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage (both initial and later) increases by 1d6 for each slot level above 2nd.
