It is possible to purchase some Conquest Point items from another nation's guards. Some Conquest Point items from other nations can be purchased, with certain restrictions. To do this, go to one of the National Conquest City Guards who works for the nation that has the item you wish to purchase. For example, if you're from Bastok or Windurst and you wish to purchase a Royal Archer's Sword, you would go to one of the guards in San d'Oria. If your nation is ranked higher than that guard's nation, you will be given the opportunity to purchase CP items. Since this is dependant on the National Conquest ranking, you can only purchase items that are available all the time, or when a nation is in second or third place in the rankings. Note that you will be charged an extra amount of Conquest Points when purchasing a CP item from another nation; the extra cost varies based on the rank of the item.
