A subclass is either an alternative version of an existing class, or one of the original classes that got renamed at the same time as receiving certain updates. Subclasses that are renamed versions of existing classes are marked with green. A character with a subclass can pick the feats of its parent class. Classes that follow the standard level progression are marked noted with AEDU (referring to At-Will, Encounter, Daily, Utility), whereas classes that follow a non-standard level progression (described at the specific class pages), are marked with E (referring to Essentials).
