Badge of Redirection

This badge is attuned to one particular type of elemental damage: Acid, Cold, Fire, Lightning, Necrotic, Radiant, or Thunder. While attuned to this badge, you can use your reaction to expend one of the badge's charges to withstand and reflect that type of damage. When you do so, the damage you take from the attack is reduced by a number of d10s equal to your proficiency bonus. If you reduce the damage to 0, you can return the remaining damage to the attacker as part of the same reaction. 

This badge has four charges. It regains 1d4 charges daily at dawn.
