Guild Wars

Two guilds agree to fight, put up gold on it, and count the bodies. While the war runs, their members may kill each other without the skulls that would normally follow — and whoever gets to the frag limit first, or is ahead when the days run out, takes both stakes.

Declaring one

From your guild's page, and only if you lead it — the stake leaves the guild balance the moment you declare, so it is not a vice-leader's to commit. Both guilds need at least 3 members, and there must be no war or unanswered declaration standing between you already.

The guild	Who you are declaring on, by name. Not yourself.
Frag limit	Kills needed to win outright — 10 to 1 000, and the form opens on 100.
Days	How long it runs if nobody reaches that limit — 1 to 90, opening on 30.
Stake	What each guild puts up, out of its balance — up to 100 000 000 gold. Zero is allowed, and a war fought for nothing but the frags is a perfectly good war.

Your stake is taken there and then. Nothing is fought until the other leader answers, and you can withdraw the declaration until they do.

Answering one

Accept and your guild puts up the matching stake. The fighting starts at once and the clock starts from that moment, not from when the declaration was written.
Reject and it is over before it began. The other guild gets its stake back — at that point yours has paid nothing.
Withdraw is the same door from the other side: the guild that declared may take it back while it is unanswered, and gets its stake back.

Only the leader of the guild that was declared on can accept or reject, and only the leader of the guild that declared can withdraw.

What changes in game

Log out and back in. Your character reads the list of guilds it is at war with when it logs in, and never again while it is online. A war declared, accepted or ended while you are playing does nothing for you until you relog — and the same goes for everyone on the other side.
No white skull. Attacking a member of the guild you are at war with does not mark you the way attacking anybody else would.
No unjustified kills. Killing one of them does not count towards a red or black skull. Kills outside the war count exactly as they always did.
Emblems change. Once your guild is in any war, your guildmates are marked as allies, the guild you are fighting as enemies, and everybody else as neutral.
Nothing else moves. Protection zones still protect, and a war is not a licence to attack anyone outside it.

Frags

A frag is one of theirs killed by one of yours, while the war is being fought. It goes to whoever lands the killing blow, not to whoever did the most damage, and a summon's kill counts for whoever summoned it. Both guilds' online members see the running score in the guild channel as it happens.

Kills before the declaration was accepted do not count, and neither do kills after it ends. The score on the guild page is counted from the record of the war itself, so it is the same number both guilds see.

How it ends

The frag limit is reached	That guild has won, however many days were left, and the whole world is told.
The days run out	Whoever is ahead on frags takes it. A level score is a draw.
A leader surrenders	The other guild wins it. Worth knowing when the other side has simply stopped playing and you would rather not wait out the clock.
A guild is gone	A war whose opponent no longer exists ends in favour of whoever is left, rather than running its full term.

The winner's guild balance takes both stakes. A draw hands each guild its own back. Either way the gold lands in the balance, where a leader or vice-leader can pay it out again.

One quirk to expect: the website decides when a war is over, and it works that out as people load the guild pages. Between the day running out and somebody looking, the war is still on as far as the game is concerned, and your characters can still fight. It settles itself the moment anyone opens the guild list.
