The new patch has been getting a pretty rough reception and has many things players are not happy about. This one, however, is definitely one that everyone will appreciate!
It seems you can now get Forgotten Souls, one of the resources needed for upgrading gear, from salvaging legendary items. Previously they only dropped from Helltides, but now it seems they have a chance to come out of salvaging items, presumably only legendaries. This is certainly good news right now, as players are avoiding Helltides due to a bug that’s causing Aberrant Cinder drop rates to be very low.
They aren’t a guaranteed drop and they definitely come from “fresh” items, and not previously upgraded ones, as BlackMetalCoffee spotted!
Fiend Roses still seem to be Helltide-exclusive, however.
