I was just thinking that since you can throw up to three shuriken per attack, would a rogue's sneak attack damage apply three times or once. And with point blank shot and rapid shot a third level rogue could bluff an opponent and then shoot off six shuriken for a total of 6 + 6 (point blank shot) + 12d6 damage, for an average of 12 + 12*3.5 = or 54 damage. In this case it would almost certainly be worth it to alternate bluffs and full attacks. He'd be rocking the casbah!
