Vanguard’s Duplicate

You create a lesser duplicate of yourself to fight beside you.

In an unoccupied space within range you create a duplicate of your self.  The duplicate acts as a creature who’s initiative immediately follows yours. As a bonus action you can command it to make a strike (based off your stats and weapons) or to cast one of your cantrips. If no command is given it will take the dodge action. It’s HP is equal to half of your HP max and shares your AC.
