You create a floating, spectral wyvern tail with a glistening stinger within range that lasts for the duration or until you cast this spell again. When you cast the spell, you can make a melee spell attack against a creature within 5 feet of the weapon. On a hit, the target takes piercing damage equal to 1d6 + your spellcasting ability modifier. The target must make a Constitution saving throw, taking 4d6 poison damage on a failed save, or half as much damage on a successful one.

As a bonus action on your turn, you can move the weapon up to 20 feet and repeat the attack against a creature within 5 feet of it.

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