Field Operations
Field operations, also known as adventuring forays and often referred to by players as exploration zones, are endgame content for several expansions of Final Fantasy XIV. They consist of large-scale battlefield duties and raids, connected by storyline quests. These are optional and are not part of the Main Scenario. Each field operation has special gameplay mechanics. The Stormblood, Shadowbringers, and Dawntrail field operations are tied to the expansion's Relic Weapons.
Exploratory Missions, Heavensward's original field operations version of the Diadem, was replaced in patch 5.21 with the current gatherer-only zone to support the Ishgardian Restoration.
Retired items may still be kept in inventory but can no longer be obtained from gameplay. Tradable items may still be obtained from the Market Board or directly trading with other players.
The removed content is described in:

The Forbidden Land, Eureka is the level 70 field operations series released in the Stormblood expansion. It consists of four zones allowing up to 144 players simultaneously:
- The Forbidden Land, Eureka Anemos
- The Forbidden Land, Eureka Pagos
- The Forbidden Land, Eureka Pyros
- The Forbidden Land, Eureka Hydatos
The series concludes with the optional high-end Baldesion Arsenal raid within Hydatos.
Players can obtain new gear, experience new gameplay mechanics such as Logos Actions, and have the opportunity to forge Eurekan Weapons, the level 70 series of Relic Weapons.
Save the Queen: Blades of Gunnhildr, called Bozja by players, is the level 80 field operations series introduced with the Shadowbringers expansion. The Save the Queen questline is a sequel to the Return to Ivalice alliance raid questline and thus requires its completion to unlock.
It comprises two 72-player battlefield duties (The Bozjan Southern Front and Zadnor), a set of normal-difficulty raids (Castrum Lacus Litore, Delubrum Reginae, The Dalriada), one high-end 48-player raid (Delubrum Reginae (Savage)), skirmishes (i.e. FATEs), trial-like encounters (Critical Engagements), and challenging duels.
Players can obtain new gear, experience new gameplay mechanics such as Lost Actions, and have the opportunity to forge Resistance Weapons, the level 80 series of Relic Weapons.
Unique to this field operation, the battlefield duties also allow players to level up their characters normally, making them a popular choice of leveling from 71 to 90.
Occult Crescent is a level 100 field operations series that was released as part of the Dawntrail expansion, starting in patch 7.25.
The first installment contains one 72-player open zone (The Occult Crescent: South Horn), a 48-player high-end raid (The Forked Tower: Blood), FATEs, and trial-like encounters (Critical Encounters).
Players can obtain new gear, experience new gameplay mechanics such as Phantom Jobs, and have the opportunity to forge Phantom Weapons, the level 100 series of Relic Weapons.
