Dead Eye( Dragon Compendium, p. 95)
[Fighter Bonus Feat, General]
Your precision with ranged weapons translates into more telling strikes than you could normally make.
You may add your Dexterity bonus on damage rolls made with ranged weapons for which you have the Weapon Focus feat, so long as the target is within 30 feet.
Dead Eye does not increase the damage dealt to creatures immune to critical hits.
A fighter may select Dead Eye as one of his fighter bonus feats.
