Problem with Sister Missions

[---No-Mercy---]

So I think these missions were bugged and/or designed to be Co-op and not done alone, I have all the requiems but the stupid cow won't spawn for me to kill her because I'm alone and recruitment is useless because no one is biting in recruitment chat?

I'm effectively STUCK?

Hi! Personally I've ran a fair share of Sisters of Parvos, majority of them Solo, and I've not had much issues with their spawn rates. Maybe you've been unlucky. Is this the first sister you're doing? Or is this a consistent issue you're facing?
Regardless, keep up with the status of your Sister's anger bar. The higher the anger, the more likely they are to spawn. And note that leveling up the Sister will reset the anger meter, such as by failing a requiem mercy attempt, or by clearing every node on a controlled planet. You might just have to run one or two more mission to increase her anger to make her spawn in the next. Let me know how it goes c:

If this isn't your first Lich / Sister, check your gear wheel to see if you have a Requiem Ultimatum. That can summon the Sister right away if you use it in a controlled node. (Best to check the wiki for other tips, like using it solo.)
