Q 23 I'm reading through Heroes of Horror, and checking out Cas the demi-god, but I don't understand how they get his touch AC of 21. You've got the flat 10, then -1 size, +7 Dex, and that's it. Where's the other +5 from something like deflection? He doesn't have a +5 ring, and his artifact weapon doesn't say that it gives it to him. Does he have his own +5 from something? Or should it be assumed that it automatically from his Combat Expertise even though it doesn't mention that?
