Basically a "Buff and go to town" build.
You could also start as a Thief but then you'd be missing on those sweet sweet Resistance points. The points in Intelligence are mainly for Great Magic Weapon (or some sorceries if you want) to help you through PvE until you get enough points in Faith for DMB and SLB (that means NG+ bitches!). Then you can switch to utility spells or pyros. You could also just put those points somewhere else. Dagger over Bandit's knife because of speed and thrusting attacks that benefit from Leo Ring.
