Queensfoil

Tincture of Queensfoil is a consumable that makes the Ascendant Challenge portal visible in the Bay of Drowned Wishes. Using one reveals the portal, which is needed to enter the challenge. Each weekly Ascendant Challenge is reached this way, and the Agonarch Abyss challenge is one of them.

The Tincture is sold by Petra Venj in the Dreaming City, and it also drops from public events, chests, patrols and The Blind Well. Dying inside a challenge returns you to the Dreaming City, and you must redo the platforming to reach the portal again.
