Just a simple question on this one. There are only 2 classes in AiF: Warrior & Mage. Should there be more classes developed for the house rule expansion? Maybe instead of classes we could come up with suggestions on using the skills with the classes to simulate a new class? Of course, that might involve expanding the skill list...

Definetly no to classes.

The concept was deliberately not included in the game. A player character advances either through succesful "warrior" combat or succesful "sorceror" spell use or both. It isn't about "class" per say but about one of two ways to advance in Levels. Also, a player can switch to either path. Al-haza began as a "knight" (p56) and became a wizard.
