Bloody Blade (Ex): The fury of your attack is terrifying to see. Whenever you deal sudden strike damage (see below) with a melee weapon, the target of the sudden strike and all opponents within 30 feet of you who can see the target are shaken for a number of rounds equal to your avenging executioner level. A successful Will save (DC 10 + your avenging executioner level + your Cha modifier) negates this effect. Creatures whose HD exceed your character level are not affected. Bloody blade is a mind-affecting fear ability.

Sudden Strike (Ex): If you can catch an opponent when he is unable to defend himself effectively from your attack, you can strike a vital spot for extra damage.

Rapid Intimidation (Ex): Beginning at 2nd level, you can attempt to demoralize an opponent as a move action instead of a standard action. See the Intimidate skill (PH 77) for details.

If you have the favored enemy class feature, you can add your favored enemy bonus to Intimidate checks made to demoralize foes of the chosen type (and subtype, if applicable).

Dread Blade (Ex): Starting at 4th level, you can exploit the terror you inspire to further brutalize your target. You treat shaken, frightened, or panicked creatures as flat-footed for the purpose of dealing sudden strike damage.

Bloody Murder (Ex): Starting at 5th level, if you deal enough damage with a melee attack to drop a creature (typically by reducing it to below 0 hit points or killing it), all enemies within 30 feet of you who can see the target become frightened for 1 round. A successful Will save (DC 10 + your avenging executioner level + your Cha modifier) lessens the effect to shaken. Creatures whose HD exceed your character level are not affected. Bloody murder is a mind-affecting fear ability.
