During Act II: Rites of the Deep, you will need to meet up with Eris to help her perform a ritual that will bind the Echo Oryx to her throne world.
Preparations were previously made, which included you obtaining the flesh of Akka and now Eris is ready to push through with her plan.
This requires that you take on several enemies before doing your part in the ritual, which should be enough to buy the Vanguard time to focus on other matters.
How To Get Mission Captis?
Mission Captis becomes available once you have reached Quest Step 16 of Act II: Rites of the Deep and is a continuation of the third week after the quest became available.
Once you have reached Quest Step 16, you may start the mission by selecting launch from the quest itself or the Last City destination.
Mission Captis Walkthrough
The mission begins with you already in the Hall of Souls aboard the Dreadnaught and from here, you will head to the area where the Hall of Souls boss is fought.
Eris Morn will be waiting for you on the platform and once you arrive, she will begin giving you instructions and afterward will disappear.
Step into the ritual circle to start the binding, which will cause The Resonant Knife, First of the Reshaped (Boss) to appear.
Ignore the boss since he can’t be damaged and instead focus on defeating the enemies and looking for the glyphs that appear.
You will notice that several Eyes of Vengeance appear in the area and when shooting some of them, they will immediately respawn.
This is part of a puzzle for the ritual, and you will need to shoot the Eyes of Vengeance that do not belong. (Remove the ones to imitate the glyph that appears)
After doing this 3 times, the ritual will be complete, and you will have completed the mission as well as Quest Step 16.
Mission Captis Rewards
Completing Mission Captis will allow you to progress with Act II: Rites of the Deep, which now requires you to visit Sloan in the Noiseless Chantry.
Verdict
The success of Eris’ mission is a huge step, and the Taken King has now been captured, which now the Taken and Dread know what they are up against.
With Oryx now captured, it is now time to report in with Sloane and afterward, return to the Shaping Slab to reflect on your path.
While Oryx has been dealt with, there are still other threats that need to be assessed but this will come later, and the Vanguard will be ready.
