Autohypnosis [Skill]
You have trained your mind to gain mastery over your body and the mind’s own deepest capabilities. This feat scales with your ranks in Concentration.

0: You gain the ability to put yourself into an autohypnotic trance for an hour as a standard action. When entering into this trance, make a Concentration check to determine the strength of the trance. Once you have entered into an autohypnotic trance, you cannot enter into another for an hour. While in such a trance, you can memorize up to (your check - 15) pages worth of written material in a minute of light reading.
4: If your Concentration check to enter into your trance is at least 18, you may ignore the effects of caltrops for the duration of your trance. If it is at least 20, you do not take damage from strenous actions while disabled and automatically become stable when dying.
9: While in an autohypnotic trance, you may substitute your initial Concentration check at a -10 penalty for your Will save against any [Mind-Affecting] abilities that target you during your trance. You must choose to do so before rolling for your Will save.
14: While in an autohypnotic trance, you may substitute your initial Concentration check at a -10 penalty for your Fort save against any poisons, diseases, petrifications or fatigue that effects you during your trance. You must choose to do so before rolling for your Fort save.
19: Your Concentration checks are no longer made at a penalty when substituted for saves.

What I do in my games is I make Concentration a Wis based skill and if your character has a power point reserve then Concentration becomes Autohypnosis. It is the same as concentration for all mechanics but you also get all the benefits of autohypnosis on top of it.
