Hobbler

Hobbler is a perk in the Fallout: New Vegas add-on Dead Money. This perk is available as an option when leveling up. It increases your chance to hit an opponent's legs in V.A.T.S. by 25%, thus making it easier to hobble the target (reducing their movement speed by crippling their legs). As with most perks that increase your chance to hit in V.A.T.S., this bonus is multiplicative, not additive. This perk is a good to use if the player has the Fast Shot trait.

Behind the Scenes
The name and icon for this perk are references to the 1990 movie Misery, in which a serial killer hobbles her favourite novelist by smashing his foot with a sledgehammer.
