Q 21 Question on advancing monsters. When you can see "Advancement" and racial HD for their size, and larger, this means you can either advance them with either the racial or actual classes, correct? Not JUST racial levels? When you see "--" after Advancement, this means nothing short of CR increasing templates can be added to it, unless it's an animal, which you could then add the Dire template which allows you to add more HD to it afterwards, right? And if it says that you can advance it with class levels, that means you don't get any more racial HD, but instead only gain class levels, but after 20 HD you have to progress as per standard epic progression like PCs do, correct?
