Destiny 2's weekly reset brings another Ascendant Challenge to complete, this one completing the Dreaming City's six-week rotation. You can see what this entails in the video above, and check out our guide for full details.
After grabbing the Ascendant Challenge bounty from Petra in the Dreaming City (she's conveniently located near the landing zone this week), you'll need to head to the Starlight Chamber Lost Sector in Rheasilvia--but be sure you have a Tincture of Queensfoil on-hand. Progress all the way through the Lost Sector and use the Tincture to gain the Ascendance buff. You'll find the portal behind the Lost Sector reward chest. Inside, you'll have to deal with enemies and some platforming to make your way to a knight enemy that has to be killed to complete the challenge and bounty--netting you some Powerful gear.
