Classes
Classes are the basic classes you can give your character in D&D. They have a range of 1st to 20th level, and the option to go epic.

Mirror Classes
Mirror Classes are a homebrew idea of mine. For now, do not duplicate the title in any of your own articles! They are classes which combine features of a character which has a split personality... In the extreme. Like the Hulk.

Prestige Classes
These are classes which give your character that something extra in a specific direction. Like a cleric, which is a basic class, who chooses a prestige class which makes him a very good healer. He'll lack something else, though.

Monster Classes
Those classes which involve a monster progression like a normal class would. for example, you can find a way to become a full Fire Giant here by starting as a first level fire giant and working your way up to twentieth level.
