Dwarven Dex Tank

This character is meant to be able to tank very effectively in every scenario.

Basics
Race: Dwarf Subrace: Derrzagon

 Abilities  (Post Subrace) STR 9 (6) DEX 18 (21) CON 18 (18) INT 10 (13) WIS 9 (12) CHA 6 (2)

This build has some lofty goals, ability-wise, and requires us to hyper-specialize in just a few abilities at the expense of the others. Namely, we want Con to 21 and Dex to 30 ASAP.

Level Progression
For the (Any) feats, I would recommend Improved Critical and perhaps Disarm.

Stats at 40
HP: 464 (904 w/ +12 CON gear)

Attacks/Round: 4

Attack Bonus: 55, unbuffed but equipped. 27 BAB, +17 DEX Mod, +3 Feats, +8 Weapon.

AC: 77 AC. 10 Base, +17 DEX Mod, +2 Shield, +8 Shield Enhancement, +8 Robes, +8 Tumble, +14 Dodge, +5 Natural, +5 Deflection

Saves: 28 Fort, 33 Ref, 24 Will, naked.

Strengths
Extremely high defensive capabilities vs bosses, groups of enemies and mages.
 * Deflect Arrows: First missile attack per round dodged.
 * Epic Dodge: First successful attack per round dodged.
 * Improved Evasion: Half damage from failed Reflex saves, no damage from successful Reflex saves.
 * Spell Resistance 80: A caster of level 44 cannot bypass your SR. Level 54 if he doesn't debuff you.
 * Damage Reduction: The first 27 physical damage from every successful attack is negated. This number will be vastly raised by high level robes and shields.
 * Self Concealment II: 20% of all attacks miss you. This will progress to 50% through legendary levels.
 * 50% Cold Immunity: Half of all Cold damage is negated.
 * Acid and Fire Resistance 10: The first 10 acid and fire damage from any attack is ignored.
 * High Tumble: Immune to Attacks of Opportunity.
 * High AC: Pushing AC past 80 should be possible with end game gear.
 * Hide in Plain Sight: High stealth skills allow engaging and disengaging from many target at will.

Weaknesses
Our dwarf is not without his weaknesses.
 * 50% Fire Vulnerability: Takes extra damage from fire, which is arguably the most common element.
 * Subpar Melee Capability: Our Attack is a bit on the low side. We will benefit from buffs and Bards.
 * Very Late Game Build: Build is not truly complete until nearly level 50.
