AD&D Podcast: The Character with Two Classes
Why people sometimes get this wrong!
This episode breaks down the AD&D rule for characters with two classes and why it causes so much confusion. The core mistake is treating it like later-edition dual-classing or multi-classing. In AD&D, a human character abandons one profession, starts another, and loses access to all former abilities until the new class surpasses the old level. No overlap, no stacking, no shortcuts.
Run it strict and the rule makes sense. It forces commitment, prevents power shopping, and makes career changes feel earned. If players understand that they quit one life to start another, arguments stop. The design expects the DM to enforce the lockout, explain it once, and move on. That friction is intentional, and it works.
This seems very silly and is kind of broken. It doesn't make sense that if, for example, the character got to level 3 as a thief and now wants to be a magic user, that he suddenly loses all those level 3 thief abilities. I think multi-classing is stupid to begin with, but this makes it even more so.
