As a thief gains levels, he becomes more and more aware of abilities
that only they have access to.  Circle is a prime only ability which
allows the thief to sneak behind its victim and stab him while they
are fighting.  While circling does not do as much damage as the initial
backstab, it is a very powerful and useful skill.
