Once you have all 5 character slots, you have a daily income of 100 gems, not to mention the gems you naturally pick up from playing the game. It might not seem worth it in the beginning, but remember that each character receives a daily quest which can easily be completed for a nice bonus of 20 gems and some exp for that character. The fourth slot costs 500 gems, and the fifth one costs 1000 gems. Speaking of new characters, you should grab all 5 character slots as soon as possible. From then on, every new character you create, even the ones that haven't reached level 70, can access the perks that your Champion levels give. Once you're level 70, all the experience that hero earns goes towards your account's Champion levels.

As of, the highest level you can reach is 70. The first thing you're going to want to do is hit max level on your main character.

You've unlocked Heroic Difficulty, which is just a re-hash of Normal, except the monsters give about 1.5x rewards but have about 4x health. ATTENTION: Feel free to share your own friend code HERE: Friend Codes, nowhere else on the wiki, to keep things clean and organised.
