How do I figure out what my flat-footed and touch AC should be? I looked in the index, but it just takes me to a page that has a description. I looked in the glossary, and that just gives a description as well.
When you are flat-footed, you lose your dexterity bonus to armor class as well as any Dodge bonus. So use the same calculation you would use for your normal armor class but don't include any bonuses from dexterity or dodge.
Against touch attacks, you lose any bonuses from armor, shield, and natural armor, but retain bonuses from dexterity, deflection, dodge, etc.
