Badge of Reflection

This badge is inscribed with a symbol pertaining to one type of magic damage (I.e. a lightning bolt for lightning damage). 

If the wearer is targeted by a spell of 7th level or lower, the spell does not affect the wearer and instead reflects back to the caster. The reflected spell is given a new Attack roll, using the same Spell attack modifier as the caster  

After this happens, the badge is destroyed.
