Sands of Inaros

Sands of Inaros is an optional Quest introduced in, involving Baro Ki'Teer's interest in the hidden treasures underneath Phobos. Completing this quest will reward the Inaros Warframe.

Walkthrough
To unlock the quest, players must first purchase the quest blueprint from Baro Ki'Teer for 200 and, and then construct it in the Foundry under the Keys section. The blueprint can also be traded between players.

Upon claiming the item, the Quest will appear in the World State Window under the Quest tab, where it will them prompt players to see a new inbox message from Baro Ki' Teer, which will start off the quest proper.

Explore the tomb on Phobos: Opik, Phobos

 * Enemy Faction: Infested
 * Enemy Level: 20-25

Baro explains that Phobos was a desolate backwater colony, which used to be the home of the 'sky worshipers', that the Grineer exterminated in the past. Despite this, the relics left behind became valuable antiques, and thus the object of interest for Baro. Players must fight through a small contingent of Infested as they proceed.

The Tenno soon reach a temple carved on the side of a mountain, where Baro scoffs his disbelief at the stories of the 'God King' called "Inaros". As the Tenno explore deeper inside a disembodied female voice begins to narrate a story about the 'Golden Skymen' - presumed to be the Orokin - who would abduct people from them, until the arrival of Inaros. The voice unnerves Baro, who can apparently also hear it speaking, asking the Tenno to stop it.

At the end of the temple path lies a large chamber with a shrine of the God King, where a large jar - the Sacred Vessel - lies at its feet, which players must take. Baro preemptively placates the Tenno by justifying the taking of a burial vessel as creating riches instead of defiling a tomb, and orders them to extract.

The blueprint for Inaros is rewarded at the end of the mission.

Fulfill the vessel's inscription
On returning to the ship, Baro exclaims his surprise at the inscriptions on the vessel being a blueprint of sorts, and wonders if a Warframe was entombed there. He then reads an inscription on the vessel, which suggests that they may need to defeat an enemy in order to fulfill its condition, and then suggests carrying the vessel into battle.

For this part of the quest, players must kill a number of the specified enemy that is represented by the glyph on the vessel, while the Sacred Vessel is equipped in the player's Gear inventory. Upon killing an example of the correct enemy, the screen will momentarily flash with the Warframe's energy color, accompanied by a distinct guttural sound.

There are three types of enemies that can be designated by the glyph - a Corpus, a Grineer, and an Infested type - which will be different between individual players. The enemies associated with a particular glyph, as well as the required number of kills, are shown below:

They must then bring the vessel back to the tomb when the required kills are met, and place it before a locked door, which will open when placed. This will reveal another vessel that the players will take back to their ship. Taking this Vessel will cause Kavats to appear, which the player must exterminate before leaving.

When completing the required kills the player will need to bring this second vessel back to the tomb, and open the door to take the third vessel. Doing so will spawn a large Tomb Guardian which looks exactly large a very large Rumbler. When killed it will split into two Guardians, and this will continue until they are fairly small, in which they will be killed permanently and the player can continue. Baro seems distressed and emotional at this point and is eager to find out more about Inaros.

The player will do this process a third time, gaining the chassis of "Protector" (Inaros). On the final time, baro will seem distressed and pleads to the tenno to save Inaros as the Grineer have caught wind of the tenno being in the area, disclaiming that he isn't in it for the money anymore. Like before, placing the vessel by the door will open it and a final vessel will appear in the center. Taking it will cause a Tomb Protector to appear, which is essentially a copy of Inaros who will use a Mutalist Cernos as well as his normal abilities. Defeating him will cause it to cover itself in a sarcophagus and cannot be harmed, and this will cause one of the large statues in the main room to come to life in the form of a Tomb Protector Effigy which takes the form of Inaros wielding a Lesion weapon. Defeating this will make the Tomb Protector rise again, and this process is repeated until all of the Effigy giants are defeated, and the tomb protector is finally able to be destroyed.

Once the required number of kills of the specified enemy has been made, Baro will instruct the player to return to their ship to further examine the vessel, where they will find the vessel's glyph now glowing. Players must then return to the temple in Opik, Phobos to return the vessel.

From the main shrine chamber, players must proceed to a designated door where they must lay down the Sacred Vessel, which will cause the door to open, and reveal another Sacred Vessel at the center of the room inside. The female narrator from the previous visit continues the story, revealing that Inaros was once a warrior of the 'Golden Skymen', until he could no longer withstand the abductions taking place, with the latest one being that of a child. This culminated in Inaros killing the child's abductors and returning him to the colony, after which Inaros 'ascended' to watch over the colony as their King. Unusually, Baro becomes unnerved the more he hears of the story, asking whether the story might be true.

At this point a large number of Feral Kavats attack, which players must eliminate. After the last Kavat is killed, Baro nervously asks the player to return to their ship.

Completing this portion of the quest rewards the blueprint for Inaros' helmet.

Fulfill the second vessel's inscription
Baro now believes that the story of Inaros was drawn from an actual Warframe, and once more tasks the player with completing the challenge of the second vessel. Identical to the previous challenge, players must carry the Sacred Vessel in their inventory and kill the required number of a specified enemy.

Depending on which faction of enemy the player received in the previous challenge, players will be assigned a target from the same faction as their second challenge, of which the available types are shown below:

Tips

 * The Juggernaut Behemoth on Eris counts towards the Juggernaut kills for Urn #3, as do the Drekar Manics on Uranus, at least three of which will spawn during every Tyl Regor boss fight.
