So most of my party got feebleminded with some nasty high level demonic magic effect. So I am now 1 INT and 1 CHA. When making animal companions or monsters, they are unable to take any feats other than a small "natural style" list, unless they have a minimum of a 3 INT. What happens to an experienced fighter who has 5 different two weapon combo feats? none of them require anything but Dex and BAB, do they still maintain these feats that normally you cant take without a 3 minimum INT, if making them from scratch?
What happens to complex skills that don't require INT, like some of the dex skills or even the Heal skill, what about knowing you can hold your breath underwater and swim, even though you have no natural swim speed?
