EDIT: After testing, I've discovered the answers to both questions are "BASE STATS ONLY!" No using fox's cunning to qualify you for Combat Expertise, for example, nor using an Amulet of Wisdom to let yourself cast higher-level spells due to stat reqs. In short, start with the base stats you plan to have throughout the game! _ _ _ _ _ _ _ _ _ For purposes of meeting prerequisites for feats, spell levels, etc., do I need a base ability score of that much, or a total score? For example, if I have 12 base STR but am under bull's strength, can I take Power Attack at level up? If I'm a level 5 Wizard with 11 INT but have a Headband of INT +2, am I able to cast level 3 spells?
