Mirror Shield

The shield has 3 charges. Any time you are
targeted by a spell that requires a ranged attack
roll, you can expend a charge and roll a d6.
On a 1 to 5, you are unaffected. On a 6, you are unaffected, and the effect is reflected back
at the caster. The shield regains 1d3 expended
charges daily at dawn.
This shield's face is perfectly polished and cannot be tarnished, reflecting light like a mirror.
