13.11 COMBAT RATINGS AND RANKINGS

(See Also: HELP ARENA, HELP RANKINGS)

Achaea has a system of ranking adventurer vs. adventurer combatants. You are
not, however, automatically in the system. You must first reach level 30, and
then type JOIN COMBAT RANKINGS, to be put in the system. The rankings reset
every season or three months, and whoever is at #1 at the end of the season
will get an honours line indicating their victory. Along with this the top
three combatants will receive credit prizes.

SEASON DATES
------------
1 January - 31 March
1 April   - 30 June
1 July    - 30 September
1 October - 31 December

Anyone caught trying to manipulate or abuse the system in a way that is
obviously unfair will be permanently banned from it and punished in other ways
as well.


COMMANDS
--------
JOIN COMBAT RANKINGS
   Puts you into the combat rankings system. You are automatically assigned
   a rank of 100, below which you cannot fall.

COMBAT RANKINGS
   Shows the combat rankings list.

COMBAT STATUS <adventurer>
   Shows the rating, win/loss record, and fight history of the adventurer.

COMBAT CHALLENGE <adventurer>
   This is how you challenge another adventurer to a ranked fight. You
   must both be standing in the Arena Staging Grounds, and the other
   person must choose to accept. You may not challenge anyone whose
   combat ranking differs more than 15 either up or down from yours.

   Once a fight is initiated, you have 10 minutes to fight it out, or the
   fight is a draw.

   Once someone has won, each person's combat rating will be altered
   appropriately. Further, the winner will get 2/3 of the total gold paid
   by both participants to use the Arena.


   A draw against a weaker opponent may indeed lower your ranking and
   increase your opponent's!


FORMULA
-------
For those who are interested, the formula used to rate people is:

NewRating = OldRating + (K * (W - (1/(10^((-Dr)/200)+1))))

K: A variable. If you've had less than 20 fights, K is 100.
   If you've had more than 20 fights:
     If your rating < 2100 then K = 32
     If your rating >= 2100 and < 2400 then K = 24
     If your rating >= 2400 then K = 16

W: A variable.
   If you won,  W = 1.0
   if you tied, W = 0.5
   If you lost, W = 0.0

Dr: Difference in Rating. It is your rating minus your opponent's.
