Select a powerful base class. The warrior (paladin subclass), as well as a powerful mage or healer are good choices. As you play, the souls will unlock subclasses for further customization. The premium rogue class can be purchased after you have an idea of how you want to proceed. Its two base attacks do physical and energy damage each, and also gain three mana. More advanced attacks will allow you to burn enemies, as well as increase damage or evasion.
