The staff sling is rather like a small piece of artillery. Used properly, it
can hurl heavy items to great distances, where they hail down on their targets
with great speed and impact. The staff sling is a little on the clumsy side to
use, and can't be used in close combat at all, but the effect more than makes
up for these restrictions.
Note that, while a 'stone'-type nonweapon item can be used with this skill,
'bullet'-type weapons are far more effective.
Syntax: use staff sling shot at <target> shoot <bullet/stone>
        use staff sling shot at <target>
