It’s located in the Bay of Drowned Wishes lost Sector , which is directly to your left when you spawn into the Divalian Mists. Pop your tincture and go through a little bit. About halfway in, not past the barricade, turn right and you’ll see the portal suspended in the air. Jump inside. The challenge this week is a little bit like follow the leader. Follow the little orb (Toland), jumping on platforms until you reach the bottom. When you do a message will appear “Toland beckons you” several small blights will spawn which slow your movement, along with two Yellow bar wizards. They will spawn thrall endlessly-take the wizards out with your super or heavy it doesn’t really matter. After they’re dead, you’ve completed the challenge! Good luck-it’s not a very difficult one this week.
