Final Fantasy XIV has Trials that are contained to the Main Scenario Quests, but also offers optional content as well. The Containment Bay S1T7 is one of several optional Trials in FFXIV that players can unlock through side content. Additionally, these Trials reference one specific previous Final Fantasy game, that being Final Fantasy VI. Unlocking and completing The Containment Bay S1T7 will also grant players access to two additional optional Trials in the Heavensward expansion.
How to Unlock Containment Bay S1T7 in FFXIV: Heavensward
In order to unlock Containment Bay S1T7, players will actually need to complete the Main Scenario Quest “As Goes Light, So Goes Darkness.” Once they have completed this quest, they will then need to head to the Rising Stones in Mor Dhona. Go to the back room and pick up the quest “The Gods of Eld.” Follow the questline to accept “When the Bough Wakes.” This will grant you access to the Trial, where you will fight Sephirot.
Outside of unlocking Sephirot, “The Gods of Eld” will need to be accepted and completed to unlock additional content in the FFXIV: Heavensward expansion. This includes the Extreme versions of Thok ast Thok and The Limitless Blue.
Final Fantasy XIV is available for the PlayStation 4, PlayStation 5, and PC.
