Duality Paradox

You create one time duplicate that lasts a number of rounds equal to the users level. The duplicate gets an initiative roll just and a turn in combat but shares your spells slots and cannot itself use metamagic. The duplicate has the same AC, HP and spells as you. Play this duplicate as if you are playing a second player character until its number of rounds are up then remove it from combat. You may create one duplicate at a time, creating a second immediately dispels the first. Once the time duplicate is dispelled, all memories and knowledge from that duplicate are returned to the user.
