Help Needed On Map Editor

[Cov]

I have been working on the map editor for almost as long as ive had the game (when it first came out). I still do not understand how to make heroes go beyond the level 10 limit. ive seen it done on Many maps but i dont know how.

it's very simple on the editor click on the advanced tap at the top then click gameplay constents and then scroll down till see you heros maxium level then enter a number.
