Seekers of the Misty Isle
Dead Eye Shot
(Player’s Handbook II, p. 78)
You carefully line up a ranged attack, timing it precisely so that you hit your opponent when his guard is down. When your target is busy dealing with an ally’s melee attack, you strike.
Benefit: By firing just as your ally connects with a blow, you take advantage of the distraction to strike the same enemy when his guard is ruined. If you ready a ranged attack to occur when an ally strikes a particular target and your ally succeeds, that target loses his Dexterity bonus to AC against your attack.
Special: A fighter can select Deadeye Shot as one of his fighter bonus feats.
