Qiwoot is a hardcore Monk that I started Season 11 with. As you can see in the screenshot above, he obtained two Haedrig’s Gifts – which means he has four pieces of the Raiment of a Thousand Storms set.
Sadly, Qiwoot didn’t make it through Season 11. At the time I am writing this, there are a few more days left in Season 11. If I try to complete Chapter IV, it cannot be with Qiwoot.
