How to Continue the Mask of the Revenant Quest

The Unum chooses Nakak to receive a strange mask. A mask that leads to even stranger visions. What lost story does the Unum want to tell?

—Quest Description

Mask of the Revenant is an optional quest that revolves around a decorative mask for the Operator. The mask tells the tale of a Warframe left behind to prevent the return of the Sentient Eidolon, and upon completion: rewards the blueprint for the Revenant Warframe.

"You're not supposed to be in here! You're going to ruin the surprise!"

The following article/section contains spoilers. Please finish the quest before proceeding.

The quest can be initiated from the Cetus vendor Nakak once the players have achieved the Observer (second rank) with The Quills, and has talked to her with the "Mask?" prompt. She will inform the player that she received a strange mask, called the "Mask of the Lost One", from Onkko, and will sell it for 1 Cetus Wisp.

A New Threat Looms [ ]

The player must equip the Mask of the Lost One on their Operator (as a hood on the transference suit) and head into the Plains of Eidolon at night. They must then follow the marked white waypoint at the southwest side of Gara Toht Lake. Spotting a large spectral silhouette of an Eidolon that vanishes into the ground, the player must look around the shoreline in Operator mode for a small blotch of energy with a hand reaching out from it and interact with it. Nakak will then receive a vision from the Unum, explaining that the lake is where Gara had felled the Sentient, and a warden was placed to prevent the Sentient from resurfacing until the warden was lost.

Nakak will ask the player to rebuild "the lost one", mentioning that the Grineer have found relics and suggests talking to Konzu. The player must now initiate a Bounty until they find and build any part of the Revenant Warframe.

If the player already has one component of the Revenant Warframe, or purchased a pre-built Revenant from the Market, Nakak will tell the player to proceed.

A Terror Long Forgotten [ ]

The player once again must return to the Plains of Eidolon at night. The white waypoint directs the player to the northeast side of Gara Toht Lake, where the specter appears and the player must interact with another small blotch of energy. Nakak sees another vision from the Unum, mentioning that the warden continued to strike down the Sentient until it briefly hesitated at one point.

To proceed, the player must return to Bounties to find and build a second part of the Revenant Warframe.

The Lost One [ ]

The final blotch of Sentient energy resides on a river between Gara Toht Lake and Renthi Spring, and again is only visible during the night. Nakak receives one final vision where the lost one foolishly extended a hand to the Eidolon, allowing it to emerge and use him as an anchor to pull itself up, forcing the Warframe to cast himself into the lake to seal the Eidolon.

Just as Nakak finishes the tale, a Revenant Specter appears and begins attacking with its Phantasma . Nakak tells the player to defeat the specter that serves as the mask for the Eidolon. Defeating the Revenant Specter will yield the blueprint for the Revenant Warframe.

After building Revenant, a Warframe now infused with the powers of the Eidolon, Nakak warns the Tenno that she had a dream of a new Eidolon emerging and they will need this Warframe's power to combat the new threat.

Tips [ ]

If players are having trouble defeating the Revenant Specter, the fight can be cheesed in various ways:

Trivia [ ]

Prior to Update 23.10 (2018-10-12), this quest was not listed in the Codex.
Mukha (मुख) is Sanskrit for "face", both rather fitting by virtue of being Nakak's cousin, and ironic as he is only mentioned through dialogue.
The spectral silhouette of an Eidolon and the Fragments acquired in the mission depict the Ropalolyst, which prior to its inclusion in Update 25.0 (2019-05-22) was originally designed to be an Eidolon as stated in Devstream 100.
- Despite Nakak claiming Revenant 's power would be needed to combat it, the Warframe has no bearing on the Ropalolyst fight.
