Deflect Elements

You try to absorb an evocation spell and cast it back at the creature. Calculate the damage you take as if you have resistance and if you already have resistance then you do not take damage. Then, once on your next turn you can use your action to cast the triggering spell back at the original caster, if the original caster is not a valid target then you can target any one creature. You use the original caster's spellcasting modifier and proficiency bonus for this casting of the spell. Casting the triggering spell in this way does not use a spell slot and is casted at the same level the original caster used. If you cast this spell at a lower level than the triggering spell's level then the spell fails.
