How many substacks on one char?

Hi,
maybe is this somewhere posted, but I cant find.

How many substack I can do on my char?
One substack on main
and every retail subb can have substack or only one of them, or only first of them?

Thx for answer.

main + stack 85
1st sub + stack 80
2nd sub + stack 80
3rd sub + stack 80

ok, thx

I read somewhere, that only one retail subclass can make substack.

This is fine, I hope thats true.
