Some vigilantes adopt an innocent guise to cloak their acts of brutal murder.
Alignment: A serial killer’s vigilante identity must be evil. A serial killer whose vigilante identity becomes nonevil cannot gain new levels as a vigilante but retains all of her class abilities.
A serial killer must choose the stalker specialization. Her hidden strike is considered equivalent to a sneak attack with the same number of dice for the purpose of meeting prerequisites or using abilities that depend on sneak attack.
This alters vigilante specialization.
At 3rd level, a serial killer adds 1/2 her vigilante level as a bonus on all checks in a chase and to the DCs of Diplomacy checks to gather information about her and checks to track her or notice her tracks (though not to the DC of the profiler’s expert profiler ability).
This ability replaces unshakable.
At 4th level, a serial killer gains the studied target ability of a slayer 3 levels lower, including the ability to study multiple targets simultaneously at the appropriate levels.
This ability replaces the 4th- and 14thlevel vigilante talents and the 9th- and 19thlevel social talents.
This ability replaces startling appearance.
At 6th level, a serial killer gains the ability to make a death attack as if she were an assassin (DC = 10 + 1/2 her vigilante level + her Charisma modifier).
This ability replaces the 6th-level vigilante talent.
The serial killer chooses her calling card when she gains this ability, and the first time she uses it in an area where she has renown (as per the renown social talent), it becomes associated with her killings. After that, once citizens of a new settlement find this calling card, the serial killer immediately establishes the settlement as an area of renown for her vigilante identity without spending additional time to spread tales, and the Intimidate bonus from renown increases by 2. She still must spend time to establish her social identity’s renown.
This replaces the 7th-level social talent.
At 11th level, a serial killer gains Dreadful Carnage as a bonus feat, and if she leaves a calling card, the murder is so horrifying that creatures examining the corpse are affected as per nightmare that night (DC = 10 + 1/2 the serial killer’s vigilante level + her Charisma modifier). The nightmare affects a number of creatures equal to the serial killer’s Charisma modifier, starting with the first creature to examine the corpse.
This replaces frightening appearance.
At 12th level, a serial killer gains the quiet death class feature as if she were an assassin.
This ability replaces the 12th-level vigilante talent.
At 17th level, a serial killer gains the swift death class feature as an assassin.
This ability replaces the vigilante’s stunning appearance.
