Once per day, when you cast a spell, you can weave a second spell of the same level into the casting. Both spells require their own spell slot as normal, and both must be cast as part of the same action, targeting the same target(s) or area where applicable. Declare your intended outcome for each spell before resolving either.

If both spells achieve their stated intent (both hit, both effects land, etc.), you regain one of the two expended spell slots.

The first time you use this feat, you gain the Fraying feat. Each time after that you use this feat, Fraying's effect triggers.
