I looked through several pages and the FAQs and did not see an answer.
How do I level my heroes?
To level your heroes you must take them into battles. Dungeons or raids against other players will work. Your hero will begin gaining levels. Once your hero reaches an increment of 20 (20, 40, 60, 80, 100) he will stop gaining levels. You will now have an "Upgrade" option when visiting your hero inside the Hero Altar. If you press this it will show you the needed resources for your hero to gain a "star rank". At each increment of 20, you will have the option to upgrade your hero's star rank.
