Swift Swap

You use an action to designate a nonmagical object that can not be bigger than one square foot by touching it. Until the end of the spells duration you can use an action to swap the position of that object with any other object within 15 ft of it that fits the same criteria. When using this on an object that is not in your direct sight you can only perform the swap on an object that you already have seen in the objects range. As long as that object is still within the designated objects range it will work.  No matter if it worked or not when the action is used for the swap the spell ends.
