The build is for high static Doubleshot with bard as well as having assassin's trick and KTA (although only 2 ranks) and as much SA as you can fit in. The enhancement points are very tight when you shoot for Assassin's trick.
For completionist build, you could either be PDK, Human or just take 15 Rogue/3 Bard/2 Fighter.
The build assumes you have the 1 extra universal enhancement point, or you could just take 6 points in harper for 1 rank in KTA. Not Ideal though.
