If you are a leader or officer of a Guild you can enable War Mode through the Edit interface, but before you do make sure everyone in the Guild understands the rules. Compete with other Guilds who have wars enabled for War Points (WP). You can get war points by attacks, Axe Slaps and Bounties on other players that are in Guilds at war. Kills will give the highest WP reward. You are limited to how many times you can attack another player. Similarly to Gamer Points, at the end of each season Trophies, Ranks, and Experience rewards are given out for War Guilds. Keep in mind that if you leave the guild before the end of the current season, you will forfeit your rewards — and if you leave after the season ends, you will be unable to earn GP for the first day of the next season in any guild you join, including the one you left.

War Rivals: If you Attack/Axe Slap/Bounty a player that is in a Guild at war, you will put yourself on that Guilds War Rival list which will allow every player in the opposing Guild to Attack/Axe Slap/Bounty within the War attack limits. Bountying an enemy player will also add you to their personal rival list which will open you up for the 24 hour attack retaliation. Attacks or Axe slaps done after the limit has been exhausted will also put yourself on their personal rival list. If you do not directly attack a player that is a higher level than you, they will only be able to attack you until their War limits are exhausted.

War Points: You score War Points for attacking other Guilds that are in War. There are limits of War Points that can be gained from a single player daily, below are the limits and War Points rewarded:

Attacks: If a war opponent is within Experience range, on your Guilds War Rival list or in your Rival List, you can attack that player five times before you reach your daily limit for that opponent. Four War Points for an attack win and three War Points for an attack loss. Hitlist kills reward War Points regardless of attack limits. Points are only credited to the attacker.

Bounties: If a war opponent is within Level Range you can bounty that player 1 time for War Points before you reach your daily limit for that opponent. Ten War Points are rewarded for a successful bounty. Level Range Explained: If your level is greater then the target's level, your level must be less than three times their level. If your level is less then the target's level, their level must be less than three times your level.

Axe Slaps: You can slap an opposing Guild player that is in a War 4 times before that targets War Points become exhausted for the day. 1 War Point are rewarded for every successful Axe Slap on a War target.

Note: War Mode is a separate mode from Guild Wars.
