Mad Rush (Ex)

Whenever the vigilante charges, he can make a full attack. Whenever he uses this ability, he takes a –4 penalty to his AC until the start of his next turn (in addition to the AC penalty for charging). Only an avenger vigilante of at least 12th level can select this talent. Mighty Ambush* (Ex): Once per round, when the vigilante succeeds at a hidden strike, he can instantly drop the damaged enemy unconscious for 1d4 rounds. A successful Fortitude saving throw negates this effect (DC = 10 + 1/2 the vigilante’s class level + the higher of the vigilante’s Strength and Dexterity modifiers). Whether or not a creature’s saving throw is successful, it can’t be affected by that vigilante’s mighty ambush again for 24 hours. Only a stalker vigilante of at least 10th level can select this talent.
