First off the requirments:
1) First each town leader must pick a building,
2) An admin will spawn a gold helmet
3) That gold helmet will be placed on the top floor of the chosen building
Ok so how this works is if towny war is declared one armour must enter the opposing village and take the golden helmet.
Rules:
1) You cannot sneak into enemy buidling to take helmet if war is not declard.
Thats all!
