Two guilds can go to war one against the other.
- Declaration must be accepted by both sides.
- Once the declaration is accepted, no recruitment is possible.
- War starts 24 hours after declaration, lasts 3 days.
- Gold and fame loss is halved, though the winner gets the full ammount. (it injects some extra gold in the economy, but I figure people need an incentive to fight in the first place)
- Total gold and fame from raids is turned into points. Guild with most points is the winner. Not sure about a prize for that, a badge or something symbolic should be enough.
