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.

Behind the Scenes

 * A hobbler is someone who puts a device on horses' legs to stop them from moving any quicker than a slow shuffle.
