Sub-Class

This is a homebrew rule that allows someone to have a second class without gaining a level. these must be specifically sub classes though and grant access to feats only those classes may have. Most are production classes that give bonuses or abilities to create items or change the world somehow. Some, however, are combat or action-oriented. for instance, locksmith not only can pick locks but change the key needed to open them.
Only one subclass can be had at a time. but you may drop them at any time. If you drop your subclass then you lose all feats, and abilities associated with that subclass. You are then free to take up any other subclass if you meet the requirements. Every subclass builds into either a hidden or gifted class.
