01What is it about?
A Sister of Parvos is an elite Corpus fighter chosen by Parvos Granum. Like a Kuva Lich she is immortal and becomes your personal nemesis. She occupies planets, takes some of your credits and sends her Hounds after you. Crack her Requiem sequence and you get her Tenet weapon and her Hound as a companion.
The key terms in short:
- Candidate
- A Corpus hopeful who can appear after the Granum Void. Finish her with your Parazon and she becomes your Sister.
- Granum Void
- A short bonus challenge in Corpus ship missions. You open it by offering a Granum Crown at a golden shrine on the map.
- Hound
- The Sister’s robot dog. They hunt you on her nodes, and after the win you get one as a companion.
- Requiem mods
- The same eight Parazon mods as for Kuva Liches. Three of them in the right order break the immortality.
- Murmurs
- Knowledge you collect from her Hounds. Enough Murmurs reveal one Requiem mod.
- Tenet weapons
- Upgraded Corpus weapons with a bonus element of 25 to 60%.
02How to create your Sister
- 01
Meet the requirements
Finish “The War Within” and “Call of the Tempestarii” and reach Mastery Rank 5.
- 02
Get a Zenith Granum Crown
It drops from the Treasurer, a special Corpus enemy in Corpus missions of level 30+. The crown opens the hardest tier of the Granum Void. The Candidate only appears if you earn at least the tier 1 reward there.
- 03
Corpus ship mission level 10+
Play a mission on the Corpus Ship tileset and open the Granum Void with the Zenith Crown. Syndicate and Void Fissure missions do not count.
- 04
Hunt the Candidate
After the Granum Void the Candidate appears. She can flee, so deal with her first.
- 05
Check the weapon and finish her
Knock her down and get close to see her Tenet weapon. If you like it, do the Parazon finisher. In a squad only the last player who hit her can do this.
03Progenitor Warframe: the bonus element
Just like with Liches, the Warframe you finish the Candidate with decides her Tenet weapon’s bonus element and her abilities. She is usually immune to her own element. The mapping is the same as for Liches. Here are all Warframes by element:
04Hounds, Murmurs and Requiem mods
Instead of Thralls your Sister has Hounds. They are their own enemy type, not converted Corpus. On her nodes one Hound appears right at the start, up to three per mission. Finish them with the Parazon to collect Murmurs.
- Hounds take 25% less damage and are aggressive. They actively seek you out.
- Each Hound has a 5% chance to drop a Requiem Eterna Relic.
- More relics come from Kuva Siphon missions (50%) and Kuva Flood missions (always).
- They are the same Requiem mods as for Liches. They have 3 charges and are tradeable.









Finding the order works exactly like with a Lich: equip mods, knock the Sister down, use the Parazon, check her profile and swap.
05Ranks and credit tax
| Rank | Planet | Enemy level |
|---|---|---|
| 1 | Venus | 55 to 75 |
| 2 | Phobos | 50 to 60 |
| 3 | Jupiter | 55 to 70 |
| 4 | Neptune | 75 to 90 |
| 5 | Pluto | 90 to 110 |
Every failed Parazon attempt makes the Sister rank up. On her nodes she takes only credits, but a bigger share. You get it all back after defeating her.
Once you crack the sequence, she flees to Neptune Proxima. This Railjack mission needs one Railjack Intrinsics category at rank 3. On her ship you fight her, her Hounds and two Warframe Specters. She stays invulnerable until her backup is down.
06Vanquish or convert?
| Choice | What you get |
|---|---|
| Vanquish | Her Tenet weapon and a Hound named after her, both ready in the Foundry. Everyone in the squad gets a random Hound part blueprint. |
| Convert | She becomes your ally, sometimes helps you in missions and can serve as Railjack crew. No weapon and no Hound. |
Either way everyone in the squad gets a Corrupted Holokey, you get her Ephemera if she had one, and your stolen credits come back.
07Tenet weapons
Sisters carry eleven different ranged weapons. The melee weapons and the Tenet Ferrox are only sold by Ergo Glast in the Relays.
- Weapons from your Sister are claimed from the Foundry without a Mastery requirement.
- Ergo Glast sells each weapon for 40 Corrupted Holokeys. There the weapon’s Mastery Rank applies. Element and bonus change every 4 days, and you can buy each weapon once per rotation.
- Corrupted Holokeys also drop from Railjack missions with a Void Storm.
- Like Kuva weapons, Tenet weapons go up to rank 40 with
Forma and can reach a 60% bonus through Valence Fusion.
08Differences to Kuva Liches
| Kuva Lich | Sister of Parvos | |
|---|---|---|
| Faction | Grineer | Corpus |
| Created from | Kuva Larvling in Grineer missions | Candidate after the Granum Void |
| Helpers | Thralls (converted Grineer) | Hounds (up to 3 per mission) |
| Tax | Almost all rewards | Only credits, but more of them |
| Planets | Earth to Kuva Fortress | Venus to Pluto |
| Finale | Saturn Proxima | Neptune Proxima |
| Extra reward | Kuva on Parazon attempts | Hound and Corrupted Holokeys |
Frequently asked questions
Where do I get a Zenith Granum Crown?
From the Treasurer in Corpus missions of level 30+, for example Psamathe or Larissa (Neptune), Acheron, Cypress or Hydra (Pluto). On the Steel Path every Treasurer drops a Zenith Crown. The Granum Void also needs the quest “The Deadlock Protocol”.
I am new. Is a Sister a good start into the nemesis system?
She is a bit easier to start with than a Lich because she only steals credits. Enemies still climb to level 110, though. Start once you have a solid Warframe and a good weapon.
Can I get Tenet weapons without a Sister?
The melee weapons and the Tenet Ferrox, yes, from Ergo Glast for Corrupted Holokeys. The other ranged weapons only come from a Sister or a traded converted Sister.
Do I have to fight her with the same Warframe?
No. The Warframe only matters when you create her. After that you can use any Warframe.
