Overall concept:
A 2wf pure gnome barbarian, combining the crit multiplier boosts from frenzied berserker with the critical threat & damage boosts with light weapons from the racial line.
My own one is a TR and had a bunch of tomes etc. but the general build concept should work for a first-lifer or a TR, and vanilla or deep gnome easily enough. For some reason I can't get the character generator to run, so certain things like starting stats might not be perfect.
Race: Deep Gnome (LR'ed out the initial wiz level)
Starting stats: (36 point build with +6 tomes across the board)
STR - 14 - increases go here, or in dex if necessary to make up for lack of tomes
DEX - 14
CON - 15
INT - 16 (i like having skill points! this can easily be reduced & reallocated)
WIS - 11
CHA - 8
Feats, in no particular order:
Power Attack
Cleave
dodge
mobility (just couldnt think of anything better at 30 & extra dodge & dodge cap was useful)
2wf
i2wf
g2wf
perfect 2wf
improved critial: piercing
Overwhelming criticals
blinding speed
epic damage reduction
dire charge
elusive target
scion of the the shadowfell
Enhancements:
Racial 17 AP - 1st core, illusory escape, underdark experience x3, permanant blur, hardy nature x2, nimble reaction x3, full gnomish weapon training line.
Frenzied berserker 42 AP - all cores including capstone, extra rage x3, cracking attack x3, blood tribute x3, blood trail x3, supreme cleave x3, crazy strike x3, exhausting blow x3, constitution x1, focussed wrath x2, lash out x3, accelerated metabolism x1, tantrum x1

Assorted notes:
First off, I know, arborea would be the most effective scion feat - but it breaks celestia which i'm rather fond of, so am instead currently running shadowfell for the vampirism effect, which combines nicely with a new cannith crafted vampiric weapon or even 2 in particularly high-incoming-damage content
EDIT: Cannith crafted vampirism has the internal timer, so instead I used stat damage for the extra effect, usually wisdom since its a handy aid for any crowd-control specced casters.
Weapon-wise I typically use shortswords since I already had a load from previous ninja & swashbuckler lives, though light picks are tasty for particularly big crit numbers too.
Decided to stay with medium armour for the higher dodge - at 28 i started using the legendary hardened hide, which with the mobility & racial bonuses gives me 21% - not too shabby, though heavy armour using the shadow dragon plate would be a pretty effective option too. Personally, I prefer not getting hit Am also looking into some medium ToEE armour & weapon set for the yummy set bonus.
Destiny-wise I'm currently working on the arcane sphere (boo!) but have pretty much all the rest unlocked & at cap my twists are lay waste, momentum swing, ephemeral evolution & fast healing. Adjustments will naturally be made when running in other destinies, which will be the usual suspects - divine crusader, legendary dreadnaught, primal avatar & fury of the wild.
Overall, it's a fun little build that dishes out decent damage, has good durability & some handy mobility & additional defences.
