SIsters of Parvos are similar to Kuva Lichs in Warframe. These are enemies that players can generate based on their own actions in the game. To create a Sister of Parvos, players will need to complete War Within and Call of the Tempestarii.
Players must not have an active Kuva Lich if they want to generate a sister, so make sure you are dealing with any Lich that is currently on your trail.
How to create a Parvos sister
Players must enter the Granum Void found in Corpus Ship sets. With the Zenith Granum crown on the Golden Hand Tribute, players can enter the Void and fight the Errant Specters. If you reach at least 1st place in the Granum Void, you will call a nurse.
After returning to the corpus ship, the candidate will appear on the level. The player who shoots down the Candidate will be the one who can kill him with Mercy using his Parazon. Once this candidate is shot down, Sister’s weapon is displayed above them and is open to kill Parazon Mercy if this sister is desired.
By choosing to kill a candidate by merciful killing, it will cause the sister to be created in the system of origin in the same way as Kuva Lich, become the ancestor of this sister, and the Warframe used to do so will be recognized as the ancestor of the Warframe.
Below is a table with the Progenitor Warframe for each element. Prime Warframes generates the same elementary type for the Lich as a standard Warframe.
|Cold||Frost, Gara, Hildryn, Revenant, Titania, Trinity|
|Electricity||Banshee, Excalibur, Limbo, Nova, Valkyr, Volt|
|Heat||Chroma, Ember, Inaros, Nezha, Protea, Vauban, Wisp|
|Impact||Baruuk, Gauss, Grendel, Rhino, Sevagoth, Wukong, Zephyr|
|Toxin||Atlas, Ivara, Khora, Nekros, Nidus, Oberon, Saryn|
|Magnetic||Harrow, Hydroid, Lavos, Mag, Mesa, Xaku|
|Radiation||Ash, Equinox, Garuda, Loki, Mirage, Nyx, Octavia, Yareli|
When you return to your Orbiter, the name Sisters will be revealed and it will take over the previous Kuva Lich screen to display all of her attributes and abilities along with her hound. Moving to a node of influence in the Sisters domain means that you will potentially have to take over her hound.
As you continue to fight Sister’s Hound on the affected nodes, the chances of your sister appearing on the mission increase. The process of testing a Requiem order on your sister is similar to that of Kuva Liches, because failure increases it, but instead of providing Kuva, you and your teammates can earn between 5K-10K credits for attempting a Requiem.
Once you have performed the correct Requiem Mods sequence on your sister, she flees to the final guaranteed showdown in her Capital Ship at Railjack in Neptune Proxima. You will need at least Pilot Intrinsic 5 to access the node. Matching is set up to pair you with other players who are chasing their own sisters, and you will gradually accept them as a group.
Complete the Railjack target and gain access to the main ship. As you navigate the corridors of the main ship in search of your sister, you must defeat the Warframe Specters, whose job is to protect her.
Once you parasonize the Requiem sequence, you have a familiar decision to either convert or defeat your sister. Transferring a sister will get you back all the stolen credits, allow her to randomly join you on a mission as an ally, and become eligible for a Railjack Crew Vanquishing your Sister crew member.
