usage: rob <monster or player>
-or-
       rob <monster> <#>
  
Players may attempt to steal items from monsters or other players. Your
chance of stealing something is based upon your thief skill level and
dexterity vs. the level and intelligence of the party from whom you are
trying to steal.

When attempting to rob a monster, you also have a chance of stealing and not
being noticed (based on the same factors as stated above).

Robbing takes action time.
