What I eventually ended up doing was getting rid of the +4 Full Plate I had, and also knocked my Amulet of Natural Armor and Ring of Protection from +3 each to +2 each. I retooled my character (which has not been used yet - I am creating it for a game on sunday); I am now a 1st-level monk and 13th level Warmage. I did not like having to wait until 15th level to get 7th level spells, but everything else was really good, so I decided to live with it.
As for equipment, I have a Cloak of Charisma +6 and an Ioun Stone that boosts my Charisma by 2. I also have an Amulet of Natural Armor +2 and a Ring of Protection +2, and Gloves of Dexterity +4. I also bought a Robe of the Archmagi.
I took the feat aestic(sp?) mage from Complete Adventurer, which, among other things, let's me add my charisma bonus to my AC when I would be able to add my wisdom bonus (hence the level of monk).
After everything is said and done, I have an AC of 33 (10 base + 5 from the Robe, +9 from Chr, +5 from Dex, +2 from Nat. Armor, +2 from Ring of Protection). My touch AC (which should exclude Armor and Natural Armor) is 26 (10 base + 9 chr + 5 dex + 2 ring of protection) and my Flat Footed AC is 19 (10 base, 5 armor, 2 Natural, 2 Ring of protection).
Can anyone please check over my AC and make sure I have done everything correctly? I would really appreaciate that, as I consider not following the rules to be cheating, even if you didn't follow the rules out of ignorance. I don't like to cheat, and therefore want to do everything in my power to make sure I am not cheating.
