Usage:
feint

A feint is a fake attack meant to mislead your opponent and make them
more vulnerable to followup attacks.  The low level 'feint' skill allows
you to use feints in battle.

If you successfully feint, your enemy will be open to an attack of
opportunity, and will have a harder time dodging, parrying, or blocking
your attacks for a short time. Falling for a feint can also demoralize
an opponent. Feinting an enemy also decreases the amount of time it
takes for attacks such as flourish, flick and crippling strike to regain
full effectiveness.

High impact weapons like hammers and axes are more difficult to feint
with, as are two-handed weapons. Enemies with a high dexterity compared
to yours will be harder to feint, and enemies that are smarter than you
will also be harder to feint. Note that truly stupid, unintelligent
entities are completely unaffected by feints, as they lack the
intelligence to plan ahead.

Feinting works best in conjunction with other melee combat skills, as
it not only weakens an opponent's defenses and demoralizes them, but
also makes them easier to disarm and trip.
