In addition to advanced classes, some sources offer a number of prestige classes. These classes have requirements that are more restrictive than advanced classes, and therefore reflect a deeper specialization or expertise. In general, prestige classes are accessible after 8 to 10 levels, and often have requirements only found in advanced classes.
