Aldra's Mirror Spell

You attempt to send a spell that was cast by another creature back to the spell's caster. If the creature is casting a 5th level or lower spell that would affect you, you can change the target of the spell to be the spell's caster and the spell is treated as if you cast the spell using the original caster's spell attack and save DC. If the spell is 6th level or higher, you must make an ability check using your spellcasting modifier with a DC of 10 + the spell's level. The spell is reflected on a success.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the spell is reflected if its level is less than or equal to the level of the spell slot you used.
