Arrow of Crackling Shock

Arrows are used with a weapon that has the ammunition property to make a ranged attack. Drawing the ammunition from a quiver, case, or other container is part of the attack (you need a free hand to load a one-handed weapon).

These arrows look entirely normal except for a faint crackling-darkblue glow seen and even heard, coming from the arrow head.

On a hit, these arrows shatter, dealing an extra 2d4 lightning damage to the target, and any enemies within 5ft must make a DC10 CON saving throw, or take 2d4 damage on a failure.
The arrows are destroyed in the process.
