From publisher blurb: (Sung to the tune of “If You Are Happy And You Know It”) “If you get distracted and you know it play this class! If you multiclass and you know it play this class!! If you get bored with one class and you really want to show it, play this class! " The Dilettante is a base class that gets the 1st level ability of other base classes (and later on, some prestige classes). There is more to it than that (variable ability scores, unique saves, two different chassis, etc) but that's a whole lot of chaos in a very small package!
