I've posted this before, but it's still my favorite build because it gets me OP so fast.
Gnome with the Professional Knife Tosser background. Start with one point in DX, two in CN, two ranks of Throwing (the background bonus effectively makes it three ranks) and the shopkeeper's boomerang.
By the time I hit Shrouded Hills, I'll have added two ranks of Haggle, one or two spells (usually Minor Healing and Purity of Water), and a point in Persuasion. I'll sell off whatever I can to everyone except the junk dealer or the Wise Woman until I can afford apprenticeship, and then 500 more coins to purchase expertise. (As a gnome, my Haggle bonus means I can purchase expertise with only two ranks, and therefore with the 10 WP which, as a gnome, I also already have.)
Once I have expertise, all those items that only the junk dealer would touch, like the dynamite and the grenades, turn out to be worth hundreds of coins each. By the time I'm ready to move on, I've purchased Throwing apprenticeship, persuaded my way past the bridge brigands, and power-shopped the Wise Woman for the mystic chakram, which will be my go-to weapon for the first half of the game.
From there on, it's a matter of boosting my DX, CN (for better fatigue recovery) and MA with more spells. (You want OP? 20 DX, for the speed bonus. Enchanted War Boots, for even more speed. The Hasten spell, which doubles your speed while in combat. You get so many attacks, you could probably win most fights with that original boomerang!)
And then, of course, there's the Gods' Quest....
