Occasionally, there are pk battles between clans that take place in the PK
arenas.  An arena and a time will be selected, and at the designated time
the battle will begin.  At the end of the battle (either a certain number
of kills reached or time limit expired), winning clans will be selected
based on the following rough criteria:

DEFENDER trophy - this trophy goes to the clan that lost the least ground
(but did not advance) since the last battle.  Only clans that participated
in the previous clanwar are eligible. If no clan qualifies, there is no
defender trophy.  Note that winning first place twice in a row guarantees
that your clan gets the defender trophy.

AGGRESSOR trophy - if the first place winner does not get the defender
trophy, they are guaranteed to get the aggressor trophy.  Otherwise, the
aggressor trophy goes to the clan that advanced the farthest in the
rankings compared to the previous battle.  If no clan qualifies, there is
no aggressor trophy.

HEALER trophy - the highest ranked clan that has not received either
DEFENDER or AGGRESSOR.

These three trophies add a bonus to all members of the clan for the
duration of the trophy.  The bonuses also vanish when a clan war is won.

If a clan war is not currently in progress, players may start one for 50
credits using the 'credit buy clanwar' command.
