Fast hero leveling?
what is a way to level up your hero fast?
This board is not for asking questions, but for answering them. There is a "Help and Questions" board that would be better suited for you. But, just for the sake of being mildly useful, the most effective way to level up your heroes is to attack NPCs. I use Level 10 NPCs to train my heroes, which give 1.8 million experience per attack, but for lower-level heroes hitting Lv5s are better, as these give no losses and still around 93k experience.
