After receiving a letter sent by Tyrael, you previously made your way to Zarbinzet and met a person named Dannica, who seems to have witnessed a few odd events.
Dannica mentioned the strange disappearances and showed you evidence regarding the Ullo Sar, a Death Cult that has been on the move.
You will need to search for traces of this cult and see what they are up to, as well as put a stop to whatever chaos they plan to begin.
How To Get Sins of the Ullo Sar Quest?
The “Sins of the Ullo Sar” seasonal quest becomes available after the completion of the “A Gospel of Despair” seasonal quest.
This will be after you have read Tyrael’s letter and have spoken to Dannica in Zarbinzet regarding the Death Cult known as the Ullo Sar.
Sins of the Ullo Sar Walkthrough
After speaking to Dannica, make your way to any active Helltide in Sanctuary and search for a Rupture to begin the activity.
Defeat all the enemies that appear near the Rupture, and once you have completed the activity, you will need to read “The Fearful Passage” that drops.
Once you have picked up this item and the message has played, make your way back to Dannica in Zarbinzet and speak to her.
It turns out the Death Cult has been converting the local folk into believing in their ways, and this comes as a shock to Dannica.
Dannica has instructed you to keep digging to see what else you can find out, which requires you to continue to check on more Ruptures. (Quest ends here)
Sins of the Ullo Sar Quest Rewards
After closing your first Rupture and making your way back to report what you have discovered to Dannica, the quest ends, and you will receive a new one called “Across the Threshold.”
Verdict
The first encounter with the Ullo Sar reveals that the cult’s influence extends far beyond isolated rumors, reaching ordinary people across Sanctuary.
The writings recovered from the Rupture paint a troubling picture, suggesting that the cult is steadily spreading its beliefs and drawing more followers to its cause.
With more questions than answers, the search continues as each discovery hints at an even greater threat waiting beyond the next Rupture.
