Greater Manyshot( Expanded Psionics Handbook, p. 47)
[Fighter Bonus Feat, General]
You are skilled at firing many arrows at once, even at different opponents.
When you use the Manyshot feat, you can fire each arrow at a different target instead of firing all of them at the same target. You make a separate attack roll for each arrow, regardless of whether you fire them at separate targets or the same target. Your precision-based damage applies to each arrow fired, and, if you score a critical hit with more than one of the arrows, each critical hit deals critical damage.
A fighter may select this feat as one of his fighter bonus feats.
