Zaruthustran said:Fighting with two weapons gives you an extra attack. Rapid Shot gives you an extra ranged attack. Both give -2 to all attacks made that round.
So, say you have a +1 BAB, TWF, ambi, Rapid Shot, and are wielding two daggers. You can get up to 3 attacks that round. All attacks are at -3.
Here's the math:
*Full melee attack at +1 BAB gives you one melee attack at +1.
*Fighting with two light weapons and having TWF+Ambi gives -2 to all attacks and an additional melee attack.
*Rapid Shot gives you -2 to all attacks and an additional ranged attack.
TOTAL: 3 attacks, all at -3. Two melee and a ranged, or one melee and 2 ranged (leaving you with empty hands).
I thought that fighting with two weapons limited you to melee attacks, but that rule's not in the SRD. The SRD only mentions a generic "attack", and doesn't specify melee or ranged. So, if you've got Quickdraw and Rapid Shot you can make 3 thrown attacks at 1st level (penalties reduced by TWF and Ambi).
Fighting with two weapons doesn't limit you to melee only, but the "Two Weapon fighting" feat only reduces the penalties on melee attacks, it won't reduce the penalties on any ranged attack.
In your example the extra ranged attack would be at a -5, while the two melee attacks would be at a -3.
The rule is in the SRD, it's just not in the feat section. It's in the equipment section, in the Heavy Crossbow description. Don't ask me why.
