Manyshot Feat calculations?

[dagger]

How about adding in OtBI 's (from CW) precision damage as well? Still a nice first arrow...

Don't forget Greater Manyshot (allows for multiple targets with your arrows still as a standard attack!) and Improved Rapid Shot (negates the normal -2 attack penalty for rapid shot.) which are found in ExPHB and CW respectively.

Edit: Oh, and the knockback property on a bow with a good archer ensures your opponents DON'T manage to reach you regardless of distance
