For this problem you are to join the following classes into a hierarchy (use the UML diagrams from Module 2 to get started): Player - Super Class Archer - Subclass Barbarian - Subclass Cleric - Subclass Rogue - Subclass Warlock - Subclass If the parent class has the same attributes as the sub class then you can remove those attributes from the subclass. If the class is new for this module, please come up with 2 unique attributes of your choice, and 1 piece of functionality. If the sub classes are shown on the same level, then they share a parent class.
