how to go over level 10

how to go over level 10

ive seen heros that can go to level 15 ect i know how to make spells have higher levels but not heros

how do you do it?? (i hope its not triggers)

gameplay constants. under the advanced tab in main editor window. click the "use custom constans" tab and the find "max hero level" change it to what ever you want

thanks
