Fairly sure the quest was for 10 from the start for me. First thing I do on Tuesday is pick up all the quests in my covenant and I thought I got renown 15 by turning in the ten souls.
Do not wait to pick up this quest at renown rank 15 if you are entering this week as renown rank 14. Hitting rank 15 is causing this quest to completely disappear. Putting in a GM ticket has not been helpful for me unfortunately. Regretting reading this article and waiting to pick up this quest.
Cool, I'll get 5 extra souls I won't use untill they buff the amount of anima rewarded from all sources.
I'm venthyr and I still would rather not waste anima healing them. I've done 11 of the campaign adventures and the first maw one. I have the second maw one queued right now and Venture Plan suggests I will win that and the twelfth campaign one is available so I will do it next year:)
