A nice sharpshooter build. Except that I never would play as Drow

, I prefer to take medium armor + shields at lvl 4 for protection and use hand crossbows, for a more medium ranged combat. For solo your sharpshooter build is surely better.
But my question, why do you recommend scimitars and slashing damage? I'm using shortswords (because of the style), a +1 specimen or the one with additional damage against full-hp enemies, in the rare instances I'm in melee distance. What is the advantage of slashing damage?
