Hits from crossbow bolts are known for their ability to penetrate deep into
muscle, or even into bone. This skill makes use of that by putting a bolt
through the leg of victim. The pain of the deep leg wound, combined with the
damage to muscle tissue, limits the target's ability to put weight on the
damaged leg. Done correctly, the victim will have reduced power and mobility
for a short time.
Syntax: use crippling shot at <target> shoot <bolt>
        use crippling shot at <target>
Note that, if the bolt impales your victim, it is automatically destroyed.
