A shimmering mass of nettles encompasses the end of melee weapons you hold. The next time you hit a creature with a melee weapon attack before the spell ends, the nettles violently explode. In addition to the normal effect of the attack, the target of the attack and each creature of your choice within 5 feet of it must make a Dexterity saving throw. A creature takes 4d10 piercing damage on a failed save, or half as much damage on a successful one.
