Not play tested yet, based off my idea for Force of Will

Mind Over Body [General]
Prerequisites: Iron Will, Base Will Save 5 or Higher
Benefit:  As a standard action you can focus your will into a field that protects you against physical harm.  Until your next turn you gain damage reduction equal to your total will save (not counting conditional modifiers).

Improved Mind Over Body [General]
Prerequisites: Force of Will, Base Will Save 10 or Higher
Benefit: You can use Mind Over Body as a move action instead of a standard action.
