Blur Arrow

The next time you make a ranged weapon attack during the spell’s duration, the weapon’s ammunition, or the weapon itself if it’s a thrown weapon, is under the effect of the blur spell. If the target is using a shield, this arrow or thrown weapon negates the AC bonus of the shield. If the target is not using a shield, the attack does 2D6 sneak attack damage in addition to the normal damage roll for the item.
