You channel reflective magic into your weapon or shield to slow, and possibly deflect incoming attacks. When you, or an ally withing 5 ft of you are hit with a single target spell, melee weapon attack, or projectile, you can cast this spell in response. This spell reduces the attack's damage by 1d10+your spellcasting ability modifier+your caster level. If this spell reduces the damage to 0, you can turn the attack back on the original caster, using their roll to hit, effectively attacking them with their own weapon.

At Higher Levels:
When you cast this spell using a spe slot of 2nd level or higher, the damage reduced increases by 1d10 for each slot level above 1st.
