Vital Punishment (Ex)
Source: Ultimate Intrigue, p. 17
The vigilante gains Vital Strike as a bonus feat, though he does not have to meet the prerequisites for this feat. Once per round, before he makes an attack of opportunity, he can declare it to be a vital punishment. If the attack hits, the vigilante can apply the Vital Strike feat. The vigilante can apply the Improved Vital Strike or Greater Vital Strike feat as his vital punishment instead if he later gains those feats. A vigilante must be at least 6th level to select this talent.
