Sanction is similar to Signet in concept, but it applies in different areas, namely those that were added in the Treasures of Aht Urhgan expansion of Final Fantasy XI. Sanction is given out by gate guards for the Empire of Aht Urhgan. Instead of participating in Conquest, they are instead listed as acting as a mercenary with the sanction of the Empire.
Sanction does not give Conquest Points, but instead Imperial Standing. Imperial standing can be used to buy items and equipment from gate guards as well, just like Conquest but with different available items. It can also be exchanged for Imperial Currency, which functions on Bronze, Silver, Mithril, and Gold instead of gil (though gil is used by almost all vendors). Sanction can also be used to purchase a pass to use the Runic Portal which provides easy transportation to and from various Staging Points.
The final difference between Signet and Sanction is the effects that can be added to Sanction. For the exchange of 100 Imperial Standing, a player can get a Regen, Refresh, or an effect to increase the duration of food. The Regen and Refresh effect is 1 HP or 1 MP per tick whenever the player is below a variable percentage of his or her total HP or MP, respectively. The extension on food is upwards of doubling the total time. These effects are actually dependent upon the Imperial Defense Standing at the time.
Players must complete a quest to become a mercenary capable of receiving Imperial Sanction. At that point they will be given the rank of Private Second Class. Sanction will last for 3 hours at that rank and 1 additional hour per rank above "PSC" the player earns.
Things Purchasable with Imperial StandingEdit
Use of the Runic Portal can be obtained through spending Imperial Standing. Use of the Runic Portal is free when a character has an Assault quest active; however, if the player pays 200 Imperial Standing, he or she can use the portal to warp from Aht Urhgan Whitegate to a staging point. Use of the Runic Portal from a staging point to Aht Urhgan is free.
Imperial Currency can be purchased in exchange for Imperial Standing. Imperial Currency is generally used in quests where players are asked to interact with natives of Aht Urhgan.
