Slayer

Slayer is a perk available in Fallout, Fallout 2, Fallout Tactics and Lionheart.

The Slayer walks the earth! With a successful Luck roll, all of your hits in hand-to-hand combat are upgraded to critical hits - causing destruction and mayhem.
 * Note: Despite the in-game description, Slayer does not actually require a luck roll. All hand to hand attacks are upgraded to critical hits.
