Somewhere in these threads is a screenshot of a Monk with AC 50. Inspired, I thought I'd match or beat that, which required learning how Armor Class works in toee. Discovered some interesting things, namely which bonuses stack and which ones don't. Bottom line: solo character doing his own crafting 16th level Elven Ranger 15/Mage 1 goes toe-to-toe, mano-a-mano with the Balor with an AC 0f 54, which means the Balor only hits on a natural 20 (which he does --along with the skeletons of Emriddy Meadows-- with uncanny frequency). The real trick is beefing up defense while still being able to hit an opponent with AC 37 (without using Scather). Base Armor Class: 10 Armor Bonus: 11 (Bracers AC 5 and Padded +3; also weapon w/ Defending for +3 ) Shield Bonus: 7 (Shield spell AC 4 and mithril buckler +3) Dexterity Bonus: 8 (limited to 8 by the Padded armor; DX 20 plus Gloves of Dexterity +6) Natural Armor Bonus: 8 (Barkskin spell AC 3 and Amulet of Natural Armor +5) Deflection Bonus: 3 (Ring of Protection +3) Size Bonus: 1 Dodge Bonuses: 6 (Combat Expertise activated for +5 and Haste potion/Boots of Speed for +1) ...all this and still able to hit AC 37 with a die roll of 13 or higher. And beginning attribute scores of 17, 18, 15, 14, 16, 13. The key was discovering that only and all Dodge bonuses stack (with one exception); access to Natural Armor (barkskin spell) is vital to achieving an AC 50+; and crafting Defending on a weapon does stack with the Armor bonus. Conceivably, the highest AC for a solo character at 16th level would be a gnome cleric with plant domain fighting a Giant, with all other legit AC Bonuses for a total of AC63 or 64 depending on the Size factors. The problem then is this cleric would be in such a BAB deficit that only a natural 20 would hit on attack.
