Arc Whip

This weapon was wielded by a high-ranking Air Elemental Myrmidon. Its handle is made from solid quartz-infused runeglass. When used to make an attack, a crackling thunderbolt erupts from the handle.

This magic weapon grants you a +2 bonus to attacks and damage rolls made with this weapon and it deals lightning damage instead of slashing. On a critical hit, it emits a thunder-crack that can be heard out to 300 feet and deals an additional 2 (1d4) lightning damage to the target. If the attack roll is a natural 1, you zap yourself, taking damage as if you hit yourself. If you use this weapon as the material component to cast Booming Blade, the range of the spell is increased to Self (10 feet).
