A Signet is a special type of status effect from Final Fantasy XI. They are mutually exclusive, though this is not a disadvantage since there is no overlap in their use. It has no actual effect on the player's abilities. It also does not go away, as all other status effects aside from Dedication, upon the player being KOed.
Signet, Sanction, and Sigil are all mutually exclusive. A player may only benefit from one at a time. Each grant different bonuses and only in certain zones. In this case, only benefits players on the original campaign map.
Having a signet will show that the player is participating in his or her country's Conquest. While he has this effect, a portion of his experience is automatically transfered into Conquest Points in areas subject to conquest. Conquest points can be exchanged for items and equipment as a sort of reward for their efforts.
A Signet is given the gate guards of the player's country, one representative in each of the opposing cities' embassies, and by all Ducal guards in Jeuno. The signet lasts a number of hours equal to the player's rank plus the nation's position in conquest the previous week--one hour for 1st place, two for second, and three for third. There are 10 ranks and 3 positions in conquest so a signet can last anywhere between 2 and 13 hours.
Conquest points can only be gained in areas subject to conquest, that being the main portion of Vana'diel in the 'present time' in game, all zones that were created before Treasures of Aht Urhgan and Wings of the Goddess. In game terms, this is the "middle lands."

Signet of Capture is the only signet that is used up when used. One must be bought for each use; thus, the skill trainer never lists it as "known".
