Example: You go to 13th level in Wizard. Then add five levels of Archmage. Then two more of wizard. Now you're 20th level. From that point forward, you utilize the Epic Wizard progression.
Now, what if you go to 13th Wizard. Then add two levels of Archmage. Then, for whatever reason, you go back to Wizard for five levels. Now you're 20th level.
Can you continue to add levels of Archmage as is from the Archmage progression? Or do you have to do some funky mix and match from the normal epic progression (for BAB and saves) and the Archmage progression?
Hmmmm...
