Slayer/Fallout: New Vegas

Slayer is a perk in Fallout, Fallout 2, Fallout Tactics, Fallout: New Vegas, J.E. Sawyer's Fallout Role-Playing Game, Lionheart, and a skill in Fallout: Brotherhood of Steel.

Description
The perk confers a +30% attack speed to attacks made with Unarmed and Melee Weapons (does not affect bare-handed punches, however).

Notably, the perk does not modify the AP costs of attacks, instead speeding up the attack animation.

Behind the scenes

 * The Vault Boy image of Slayer in Fallout, Fallout 2 and Fallout: New Vegas is a reference to the 1982 action-adventure fantasy film Conan the Barbarian.
 * The Slayer image from Fallout: Brotherhood of Steel shares the same Vault boy image as Better Criticals of Fallout, Fallout 2 and Fallout Tactics.
 * The name of the perk itself is a reference to Buffy The Vampire Slayer just with Buffy the Vampire removed, and was named as such because Chris Jones was a fan of the series.
