The 3rd edition abolished the practice of grouping classes directly, allowing hit dice, attack bonus, and saving throws to vary for each particular class again. 3rd edition also saw the return of the Monk as a base class, the creation of the new Sorcerer class, and the inclusion of Barbarian as a base "Player's Handbook" class, previously described in 1st edition's "Unearthed Arcana" rules and as an optional kit in 2nd edition. Statistical requirements on classes and experience bonuses were abolished, though a low score in an important statistic to a class would still adversely affect a character in it.
