+4 AC bonus as lvl 20 monk
+5 Wisdom modifier
+5 Dexterity modifier
+5 Boots of the Sun Soul +5 (Dodge)
+5 Amulet of Natural Armor +5 (Natural)
+5 Robes of the Shining Hand +5 (Armor Modifier)
+3 Cloak of Fortification +3 (Deflection)
+1 Dodge feat (not sure if this is included in character sheet figure)
I assume the base AC must be around 9 or 10 for lvl 20 character.

Actually, I did have a few mages cast some kind of lower magic resistance on me. If they realized that the monk had spell resistance that's not bad AI. Every time that happened, though, I knocked down or stunned the guy who did it. Sadly, we'll never know if the resistance-lowering spell was effective.
Oh, the monk's fists become +3 weapons at level 16.
I agree that the enemy spellcasting in this game definitely needs to be upgraded.
