Warframe Mask of the Revenant: Night Visits, the Mask and Built Parts
On this page
Reach Observer rank with the Quills, buy the Mask of the Lost One from Nakak, and equip it on the Operator with the hood closed. Visit the Plains at night and investigate the marked energy fragments, building ordinary Revenant components between the stages. Revenant Prime parts do not satisfy those gates.
Ordinary Warframes and standard quest rewards; quest and reward spoilers below.
Open Nakak’s special dialogue
Reach the Quills’ second rank, Observer, then ask Nakak in Cetus about the mask. She sells the Mask of the Lost One for one Cetus Wisp. If you just reached the rank and the dialogue has not appeared, leave Cetus and return before assuming the rank was not recorded.
Equip the item as an Operator hood and close the hood. This route specifically uses the Operator; a cosmetic on the Drifter is not the equivalent trigger. Check the appearance configuration before entering the Plains.
Follow the first night encounter at the lake
Go out at night and follow the white quest marker toward the southwest of Gara Toht Lake. After the spectral figure vanishes, look near the shoreline for the small energy patch with a reaching hand. Interact as the Operator.
The giant silhouette is a cue, not the item you collect. If you are standing at the lake with nothing interactable, check the time of day, Operator selection, closed mask and active quest before circling the entire Plains.

Build between visits instead of waiting at the marker
After the first fragment, obtain a Revenant component blueprint from Konzu’s Bounties, then craft and claim the component. Return at night for the second fragment on the northeast side of the lake. A second built component opens the next stage.
Read each Bounty’s current reward list before starting. Rotation and tier determine which component you can receive; running a random Bounty is not a guarantee of the part you still need. Do not substitute Prime components, and do not assume a Revenant already consumed by Helminth remains a qualifying built frame.

Finish the third fragment and the Specter
The final fragment is by the river between Gara Toht Lake and Renthi Spring. Investigate it at night, then defeat the Revenant Specter that appears. That encounter supplies the main Revenant Blueprint; the Bounties supply his components.
Keep distance and use the terrain while dealing damage instead of standing in the Phantasma’s fire. If the Specter does not appear, return to the current quest objective and confirm that both component stages were completed. Hunting a different Eidolon is not a replacement for this event.
Leave the plot reveal until the route needs it
The fragments tell you why the lost warden is bound to the lake. You can follow the equipment and night checks above without reading a full account of the ending. Once you have the main blueprint and the three ordinary components, the remaining task is the Foundry build, not another round of lake fragments.
