Arcane Polarity Inverter

When an enemy within 30 meters makes a Ranged Spell Attack targeting you or an ally, you may activate the Inverter as a 1 Action response. The spell is fully redirected - the original caster becomes the new target. The caster's original attack roll is used to hit and for damage; the caster rolls their own defense against it. Original targets are unaffected. Usable once per Combat.
