Crossbows have enough driving force to put a bolt through flesh, bone, even
stone and metal. A particularly well-placed shot might be able to get through
all four -- and, as such, put a bolt through someone's foot and halfway into
the floor. It's painful, debilitating, and keeps them from running away for a
few seconds.
Syntax: use stapling shot at <target> shoot <bolt>
        use stapling shot at <target>
Note that whatever bolt you use will end up snapped in half, no matter
what the outcome is.
