Consider a ranger with the quick draw feat and rapid shot, who wishes to throw daggers.
At first level, can I do any or all of the following, and at what penalties:
Throw two daggers with rapid shot, and then a final dagger with my off hand? I'd think yes, with all attacks at -4.
No, -6. Two-weapon fighting and the ranger ability don't apply to ranged attacks. You suck up the penalties for two weapon fighting with a light off-hand weapon (assuming you're medium-size).
In this case, you get the benefit of off hand weapon light and ambidexterity: -4 to each hand, plus the -2 rapid shot penalty to all.
Throw two daggers with rapid shot, and then make an attack with a short sword in my off hand? I'd think yes again, with the daggers at -4, and the short sword at -2 or -4.
As the first answer, except you get the benefit of two-weapon fighting with the melee attack, only -4 on that one.
Make an attack with a longsword in my primary hand, and then throw a dagger with my off hand? Again, I'd vote yes, but I don't know what the penalties would be.
Again, to two-weapon fighting benefit for the throw:
-2 for the sword, -4 for the throw.
Throw two daggers with rapid shot, and then make an attack with my longsword? I'd say yes, at -4 to the daggers, and -6 for the longsword (rapid shot + heavy off hand)
-8 for the daggers, -6 for the sword.
And finally, throw two daggers with my primary hand rapid shot, and two with my offhand rapid shot? I'd say no to this.
One extra attack for rapid shot.
And then if that ranger hits 9th level, and gets improved 2 weapon fighting, does that just add another dagger I can toss with the off hand?
No, The ability doesn't apply to throws. You can get an extra melee attack though.
