Thunder Sword (5e Equipment)

Weapon (any sword), rare (requires attunement)

Also known as the Levin Sword, the blade of this sword was forged in the shape of a lightning-bolt. When you hit with a melee attack using this magic weapon, the target takes an extra 1d6 lightning damage.
In addition, you can use your action to shoot a bolt of lightning from the blade. You make a ranged spell attack against a creature within 60 feet as an action. The spell attack for this effect is 8 + your Dexterity modifier + your proficiency bonus. Creatures must may a Dexterity saving throw to take half of the 3d6 lightning damage. You must finish a short or long rest before you can use this feature again.
