Someone had asked for one of my builds posted. Please note this isn't my EXACT build - but this would be what I would do now.
Human Barbarian 14 / Fighter 2
Stats (pretomes):
Str 18 + 4 levels +1 human enhancement+1 ftr enhancement = 30 unraged
Dex 8
Con 14 +2 enhancements = 22 unraged
Int 12 (I like skill points)
Wis 8
Cha 14
Skills: Intimidate, Jump, Listen - maxed; Tumble, Balance - as desired
Feats: PA, Cleave, Great Cleave, Toughness, SF: Intimidate, Bullheaded, Stunning Blow, Imp. Crit <your choice-prefer piercing for rapiers and heavy picks myself>
Primary Enhancements: Barb Imp Crit, Barb Intimidate Line, Barb Extend Rage, Barb Sprint Boost, Human Imp. Recovery, Barb DR, others as desired
Gear: GS Goggles Neg-Neg (for immunities-Tier 3 Greater Good Guard), Minos Legen, Head of Good Fortune, Bracers of the Glacier, quick change Lightning/Fire/Acid Guard Outfits of Resists, Bramblecasters, Con 6 necklace, Intim 15 Ring, Levik's Defender, Madstone Boots, Str 6 Ring
The basic idea is:
a) As a Str build barbarian, you really don't need to work hard to do decent damage. Are you going to be top end of barbs? No, but you can still get stuff dead.
b) Intimidate + DR equals immunity to most melee attacks. Piles of guards while doing this = fun and useful.
c) Cleave and GC help you hold aggro - and are a great way to do a lot of damage while you are mostly blocking.
There are plenty of quests that I won't intimidate at all; but I do plenty of damage. In the ones where intimidate is useful, I have piles of fun.
