Hey guys just started doing my shadowmoune quest, main reason being for the ach,tabard, and gold. I am currently on step 4 "Unholy Infusion". I was curious i anyone knew if the rest of these quest can be soloed at 90? Also wondering what the drop rate is and how long i should expect to wait on Shadowfrost shards. Lastly was wondering if anyone knew where i could find a guide to do Unholy,blood,frost infusion because the quest text confuses me a bit and all the youtube videos all have music playing instead of commentary.
I am also a 505 blood dk if that makes a difference thanks for the help
