A fighting technique used mostly by rangers and other two-weapon
specialists. With this maneuver one whirls one's weapons in the air in
circular patterns. Often the weapons move so quickly that the opponent
cannot follow both of the weapons and the attacker can get a devastating
blow through. This maneuver can also be used defensively.
The pattern in which the weapons are moved determines the effectiveness of
this maneuver. The maneuver can be a direct attack pattern, or a
defensive pattern. Attack patterns are designed to open gaps for your
weapons to slip through, defensive patterns on the other hand are used
for longer lasting maneuvers that improve one's defenses in order to
attempt a counter strike. The skills 'twin weapons', 'defensive
patterns', 'offensive patterns' and 'bladesinging' improve your
performance with this maneuver, as does 'improvised combinations'. Note
that shields are not considered weapons in this case, and that fast
weapons are more effective than slow ones. A list of weapon moving
patterns follows. Only rangers are taught multiple patterns, others will
only be able to use the 'cross' pattern.

Cross - a simple attack pattern 
Cat stroke - a fairly simple attack pattern 
Falling seeds - a moderately difficult defensive pattern.
Double cross - a difficult attack pattern 
Diamond lunge - a difficult defensive pattern 
Singing blades - an extremely difficult defensive pattern 

Examples: 'battle -m whirling blades at orc with double cross'.
          'use whirling blades at with cat stroke'.

Rangers can also select a default pattern to use, see the help provided
with the guild item for details.

NOTE: You can use this maneuver with only a single weapon, but with
reduced effectiveness.
