Arcane Mimicry

Calling upon residual arcane energies left by magical spells, you recreate a spell you have seen within the last minute. When you cast arcane mimicry, you choose a spell you have seen cast in the last minute. The spell must be of a level of which you can cast, and in order to do so, you must expend a spell slot of that spell's level in addition to the casting of arcane mimicry.
