At 4th level, a vanguard forms a bond with his fighting companions. As a move action, he can choose one of his current studied targets and grant half his studied target bonus against that target to all allies within 30 feet who can see or hear him. This bonus lasts for a number of rounds equal to the slayer's Intelligence modifier (minimum 1). This bonus does not stack with any favored enemy or studied target bonuses possessed by his allies; they use whichever bonus is higher. This ability replaces the slayer talent gained at 4th level.
