Lady Killer

Lady Killer or Black Widow (depending on the Player Character gender) is a Fallout 3 Perk.


 * Requirements: Level 2
 * Ranks: 1
 * Benefit: In combat, you do +10% damage against (the opposite sex) opponents. Outside of combat, you'll sometimes have access to unique dialogue options when dealing with the opposite sex. (The latter is much like the Sex Appeal Trait)

Additional Dialog
Nova in Megaton will provide you with the password to Moriartys terminal.
 * If you are Male

The vampire girl in the Family Matters quest will provide you with the password to the kid's cell.

You can talk the AntAgonizer into stopping her attacks on the town and fighting Mechanist. You also get her costume.

You can talk the Ronald Laren in the Nuka-Cola Challenge quest into a threesome (He often seems to end up dead just inside the door to the nuka-cola factory if you do this).
 * If you are Female

You can talk Burke in Megaton into leaving with you and getting someone else to blow up the bomb, or give up on the bomb entirely.

You can talk Karl (from The Family) into giving you the password to Ian's room.

You can talk Mechanist into stop fighting his nemesis, the AntAgonizer. You also get his costume.

You can talk Dukov out of his key without paying for it for the You Gotta Shoot 'Em in the Head quest.
