follow that link, it sounds kinda hard to make a glitch hero but that is the only thing that makes it hard. The believe it is hard. In realiy, it couldn't be easier!
if you stil don't get the explenation on the link, oh well, i will be nice once...
just go to the 'powers' tab, then go to a differnt hero and right after click to change the powers. The easiest to do this is to use your arrow keys to go one up or down and then click on the change butten,
i usaly make a hero with a name that begins with the name of the hero i want to edit so i can quikly press 1 button and then immidiatly click.
there are a lot of tricks u can use with a glitch hero, but you must do this or just hack it. (witch is a bit more difficult)
