Revenant guide

 Prerequisite: Rank of “Observer” or above with The Quills Syndicate.

Step 1 - Visit Nakak in Cetus and select the “Mask” dialogue option. Purchase the Mask of the Lost One from Nakak and equip it to your Operator
You can do so straight from Cetus by going to Equipment > Operator via the ESC menu while in Operator Mode!

Step 2 - Go out into the Plains of Eidolon during the night with the mask equipped. There will be a marked area with an item for you to find -- listen to Nakak’s dialogue for hints!

Step 3 - Once you have found the item, you must return to Cetus and talk to Konzu. Using the Bounty Board, select a Bounty with a Revenant Blueprint in its droptable. Complete the Bounty until you receive the Blueprint.

Step 4 - Build the Blueprint and claim it from your Foundry.

Step 5 - Repeat steps 2 - 4.
NOTE: The Revenant part you build needs to be different than the one you completed in Step 4.

Step 6 - Return to the Plains of Eidolon with the Mask of the Lost One equipped and find the item within the marked area. After doing so, yet another marker will appear in your minimap. Search the area, find the item, and follow Nakak’s instructions.

You’re done!
