Wolfbite Ring

This heavy iron ring is adorned with the stylized head of a snarling wolf. The ring has 3 charges and regains 1d3 expended charges daily at dawn. When you make a melee weapon attack while wearing this ring, you can use a bonus action to expend 1 of the ring's charges to deal an extra 2d6 piercing damage to the target. Then, the target must succeed on a DC 15 Strength saving throw or be knocked prone.
