For leveling, I'd only put one in a shot, though 5 in Take Aim is good since it comes with the stun which should help as you aim. You could rely on the small poison damage from the shot to allow for a) less ammo runs and b) more ammo in general.

The accuracy boosting passive is a good investment though, and Dodge may have its use (it is the least effective, as it at best works with throwing daggers and grenades--though I don't know if it works with daggers). Nevermind--it has its use, so it's a good shot.
