Athena's Polished Shield

You imbue a shield you touch with magical power. For the duration, a creature that holds the shield is immune to gaze based abilities (like those of a medusa or basilisk) and when targeted by a line spell, magic missile, or spell that requires a ranged attack roll, rolls a d6. On a 1 to 5 the wearer is unaffected. On a 6, the wearer is unaffected and the effect is reflected back at the caster as though it originated from the wearer, turning the caster into the target.
