Say you have a multi-class (2 classes) elf or half-elf PC thats maxed out in both of his classes. The player's like "now WTF am I supposed to do"? He asks the DM if he can start as a new class at first level while keeping his other two classes active (say he wants to become a thief in addition to his other two maxed out classes) how would you handle it (is this even permissible btb?). I thought this was mentioned someplace years ago, but not seeing it now. Is there a thread on this floating around?

A few questions:

1. would new hit points (in the case of thief d6) be added or divided (by 3)? I would think just add them on.

2. How much time would be required to get the pre-first level training down to start as a 1st level thief or MU or Cl etc.

3. Would you require some exceptional stats related to the new class to do this (the way its done with dual classing...or whatever you call it when a human takes two classes).

Thanks in advance.

BtB, it's not allowed. So you could make up what ever requirements you wanted if you want to allow it.

Won't answer all your questions, but should address a few of them.

As a DM, I will usually look for some in game reason to allow characters to try out thier non BtB ideas, as long as they're not too out there or munchkiny. In this case it would depend on what they already were, and what they wanted to add.
But even before that, in my campaign, level limits, just like ability scores, are natural limits, and just like natural ability score limits, they can be surpassed with in game justification. Level limis will slow down progression once the max has been reached, but usually not halt it.
