iirc - Maho both the combat class and the caster class, can have some sort of trade-off routine. I don't remember.
There was some trick to Maho + Apostle of Peace that yielded a loop of some sort ... it's a little hazy at this point.
Maho Caster definitely involved trading caster class levels for the Maho caster levels, and might work like the Pally/Blackguard swap.
Somebody have Oriental Adventures, to clarify this ?? !!
Trading away your base classes so you self qualify for your PrCs is just wrong and a twisting of the rules in my opinion.
The point was 2 levels go by-by, but you still have 2 hd, and those 2 hd still mean something.
The 2 levels / 2 hd that go by-by, are not Negative Levels.
So the question was: "What do you still have ?"
If those levels were Negative Levels, you don't have them, you have nothing.
If this is the case, then there would need to be a rules statement like: "This functions like a negative level."
It doesn't.
So those levels exist in a limbo of sorts.
What do they do? Nothing at all ?!
