Mission Dossier: A Sibling Squabbles a Vengeance Quest that becomes available during the Act: III Crossed Blades Episode Quest.
You have been tasked by The Deputy Commander to obtain runes from Xivu Arath’s forces and use them to mark defeated Lucent Ghosts to turn Savathun against her.
Doing this will give the impression that Xivu Arath is making a move against Savathun and will cause her to split her forces as the two become cautious of one another.
How To Get Sibling Squabbles Quest?
The Sibling Squabbles Quest can be obtained from the Shaping Slab once you have reached Quest Step 4 of the Act III: Crossed Blades Quest.
Sibling Squabbles Quest Steps
Step 1: Reap marks of Xivu Arath from Hive forces in The Nether by using Void or Strand to deal final blows
For this first Quest Step, you will need to obtain the marks from Xivu Arath’s Hive forces found within the Dreadnaught and may head over there by doing The Nether activity.
You will need to use weapons or abilities that deal with Void or Strand Damage to get marks from defeated Hive enemies.
A total of 100 Runes will need to be collected from Xivu Arath’s Hive forces.
Step 2: Crush Lucent Ghosts or defeat powerful Hive to mark their deaths with Xivu Arath’s Rune anywhere in the system
Your next objective can be completed in two different ways, which are either to crush Lucent Ghosts or to defeat the powerful Hive, which will mark them with Xivu Arath’s Rune.
Doing this in Savathun’s Throne World will grant you more progress and is also a good place to find Lucent Hive that you may defeat to crush their Lucent Ghosts.
Continue doing this until you have reached 100% progress. (Crushing Lucent Ghosts grants a lot of progress)
Step 3: Return to the Last City debrief at the Shaping Slab
After completing your objectives, head back to Eris Morn’s Apartment to complete the quest and obtain your rewards.
Mission Dossier: Sibling Squabbles Quest Rewards
After marking Savathun’s forces with Runes from Xivu Arath’s forces, returning to the Shaping Slab will provide you with the following rewards:
- Seasonal Gear (Common)
- Sigil Shards
- Essence of Desire
Verdict
Turning Savathun against Xivu Arath can provide Eris Morn with a huge advantage as this can distract them from trying to get to the Echo of Navigation.
While Eris Morn continues to hold the Echo of Navigation, Savathun, and Xivu Arath have their plans and luckily this has put a dent in them.
You will need to continue causing chaos for the sisters as their forces split up and can buy Eris Morn more time to plan her next steps.
