I've always thought there should be somesortof differeniation should be made between Hard To Crit (Undead), Nearly Impossible To Crit (Golem), and Completely Impossible to Crit (Ooze).
I was thinking of a kind of reverse Power Critical mechanic. A Special Ability called Resilient/Tough/Undead/Construct/Amorphous Physiology (based on the creature) that increases a creature's effective AC when threats are being confirmed against it. A Zombie, for instance, would have +6 to it's AC against confirms, a Golem +20, and only the Ooze woulld have complete immunity.
Possibly, Favored: Enemy and Knowledge (Monster Type) could slightly reduce that bonus by 1 for every level of Favored Enemy and by an additional 1 for every two skill ranks in Knowledge (Monster Type).
