Maximum amount of regular abilities?

What's the maximum for nonhero abilities? Or is there one? I need to know, thanks.

i dont think that there in one, but if u have more that 4, u wont beable to see all of them. like if u have 3 non hero abbilities, and then 4 hero abblilities, u will only be able to see the first hero abbility that u choose. so u can have alot but u wont beable to see them all.

I know, it's for my DC mod, each hero has 8 skills per level and theres 100 levels (Each skill gets stronger)

EDIT: So I need 800 skills for each hero. (!)
