Spearbiter

The front of this shield is fashioned in the shape of a snarling wolf ’s head. Spearbiter (Uncommon). When a creature you can see within 5 feet of you makes a melee weapon attack against you, you can use a reaction to attack the attacker’s weapon, the wolf ’s head animating and snapping its jaws at the weapon. Make a melee weapon attack with the shield. You have proficiency with this attack if you are proficient with shields. If the result is higher than the attacker’s attack roll against you, the attacker’s attack misses you. You can’t use this property of the shield again until the next dawn.
