TL/DR: Completing the quest “At Your Service” breaks the ability to obtain Emeni as a soulbind.
Patch 9.1.5 enabled all three covenant soulbinds for alt characters
- Unlocking your third Soulbind on any character allows alternate characters joining that same Covenant to start a quest that will immediately unlock their second and third Soulbind.
In the case of Necrolord’s second soulbind, Emeni, this allowed characters to unlock her from the quest “Soul Support” given by the NPC Construct Attendant next to the Forge of Bonds in the Seat of the Primus.
The issue appears when completing the storylines to rebuild the Emeni construct and unlock the Abomination Factory. After completing the quest “At Your Service” given by Emeni outside in the Butcher’s Block, Emeni moves inside the sanctum next to the Construct Attendant and the quest “Soul Support” is no longer available. At this point, neither Emeni or the Construct Attendant have a quest to unlock the soulbind, and Emeni cannot be obtained as a soulbind.
I have confirmed on another character that we can rebuild Emeni and unlock the Abomination Factory while still preserving the ability to unlock the soulbind as long as the quest “At Your Service” is not completed.
