Valinora's Reflecta

At 5th level, Valinora's Reflecta reflects any spells of the 3rd level or lower. When reflecting a spell you can direct the spell towards a target of your choice as if you were casting the spell. If the spell is 4th level or higher, you must succeed on a Spellcasting ability check against the Spells DC.  On a success you can continue the reflect as normal. On a failed save, you instantly fail the corresponding saving throw.

Casting this spell at higher level allows you to automatically reflect spells of higher levels. For each spell level above 5th your reflect spell level raises by one. So at 6th level you can reflect 4th level without a save, a 5th at 7th level and so forth.
