Before the monolithic ‘multiclassing’ of later editions, there was AD&D’s demihuman-only Multi-Class and human-only Dual-Class (or, as it was called in 1e, “The Character With Two Classes”). As they work completely differently, each provides a very different type of hybrid character, though the end result of both is exactly what you’d expect from any system that tries to mash two distinct archetypes into one uberclass abomination. Many players who started in the modern era look back upon these rules with a type of incredulous wonder.
Much of the reason for its quirkiness comes from AD&D’s variable XP requirements for each class, which meant that you couldn’t merely ‘take’ another class upon level up; you had to invest into each class individually, which created challenges when it came to the math. For what they had to work with, the solutions that Gygax devised (and Zeb cleaned up) are clever; even with the jank, they get the job done.
Before we get into the unique design of the two systems, and devise solutions for their problems, let’s look at how multiclassing has been handled elsewhere and if those examples can be of use.
