spear and board. +7 Tower shield grants 10 AC. And although a tower shield shows -2 penalty to hit if you look at the combat log there is actually no penalty!
You can almost never have too much AC and this build will have better than a typical warrior because of monkey grip and RDD +4 Natural Armor AC plus Luck of Heroes and tumble 30. (and divine shield when you need it for +6 AC or +10 AC with a +8 Cha item.
also consider taking undeath instead of luck which will give you extra turning = more charges of divine might and shield.
with dex 8 you can still wear a +8 dex item and get to the max dex bonus for mithril full plate. Cat's grace alone will give you the max bonus for iron full plate. (you might actually prize a dex item cause your reflex save is struggling though of course it gets a bonus against spells) Not to mention you are immune to electricity and fire!
