The general rule for advancing monsters is in the Monster Manual, and is invoked at the DM's option.
I have a question. If I'm playing a monster creature with level adjustment, can I use the advancing rules in the monster manual? Or does the DM level up for me and I have no choice in the matter? Or are monster creatures with level adjustment also "special exceptions"?
