Drakkor's Spell Reversal

Whenever you see a creature casting a spell targeting you of 6th level or lower, you can use your reaction to turn the spell back to it's caster as if you originally cast it.  If it is casting a spell of 7th level or higher, make an ability check using your spell casting ability. The DC equals 10 + the spell's level. On a success, the creature's spell turns against its caster.  If the spell cast requires concentration, it lasts until the start of the original caster's next turn.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the reversed spell inflicts its effects if its level is less than the level of the spell slot you used.

*Each mirror must be worth at least 250 gold pieces.  These mirrors can be stored within a magical bag you are holding, but not within a Demiplane otherwise.  Roll 2d6 to see how many of the mirrors shatter.  If the number rolled is higher than the number of mirrors you possess, for every extra mirror shattered you take 4d6 psychic damage which cannot be lessened in any way.
