Each of my characters has to run the the Shroud 20 times to get the Essence of Cleansing (or whatever its called).
Some of them have to run more now that Resist Poison has been nerfed to try to get the Yellow Dopant to remake many of my items. (honestly, still no Fortitude save roll ever?)
It has dropped for me only once that wasnt a 20th run, and if its a choice between making and cleansing a new item or breaking one down, making a new one for a different slot will win every time.
If I wasnt running 1 character per day through the Shroud I would have more time to play the other content.
It takes almost an hour to get a party together and then run it. 45 minutes on a good day.
10 would be enough I think. Having a character Shrouding for 60 days if just too much. The time sink isnt needed any more now that we have so much more content at those levels.
Thanks.
