A common tactic for rage cycling is Flawed Scarlet and Green Cabochon plus Internal Fortitude.
How it usually works: When you're done raging, you are left fatigued, and you can't enter rage while fatigued. The Ioun Stone changes all fatigued conditions into sickened instead. Internal Fortitude makes you immune to sickened while raging. Therefore, you can start and stop rages with no ill effects.
My question: Is Internal Fortitude necessary? As far as I can tell, being sickened doesn't prevent one from entering rage. If one is willing to accept being sickened in order to reset one's rage abilities, couldn't that one magic item allow cycling?
