Aundra's Nagic Bracers

These bracers have 5 charges. While you are attuned to these bracers, you can expend 1 charge after you cast a spell to reroll any roll of 1 on the spell’s damage dice - but you may not use this effect more than once per turn. You can also use your reaction when you are hit by a spell attack roll to expend 1 charge, giving you a +1 bonus to AC against it and possibly preventing the effects of that spell. The bracers regain 1d4+1 charges daily at dawn.
