Epic Classes gain regular bonus epic feats which can be selected from a list specific to that class.
e.g. Upon reaching 23 levels of Ranger a character may select an epic feat from the epic Ranger bonus list
Pre-Epic availability
If a class has bonus feats pre-epic then it will be possible to select epic feats if the character as a whole is epic.
e.g. A character with 9 levels of Ranger but a total of 21 levels. When selecting a 10th level of Ranger, the character will be able to choose an epic feat from the epic Ranger feat list in addition to the usual Favored Enemy feat options.
Champion of Torm, Fighter, Harper Scout, Ranger, Rogue and Wizard classes can all take advantage of this.
