The latest weekly reset in Destiny 2 has brought with a slate of new activities to take part in--namely the next murder mystery quest step. Among the things that high-level players will want to be sure they try their hand at is the Ascendant Challenge. This rewards you with Powerful gear, but you'll both need to know where to go and be well-equipped to complete it. You have until the next weekly reset on November 13 to complete this.
Ascendant Challenges require you to use a Tincture of Queensfoil while in the Dreaming City. This will allow you to see and travel through a portal to the Ascendant Plane (this one is located in a part of Rheasilvia, the Harbinger's Seclude), where you're faced with a tough challenge. This one involves a lot of platforming, a relic weapon, and a bunch of Taken enemies. You can see where to go and what to do in the video above.
