The Harvest Key is used to open The Harvest at the Abandoned Purlieu in Revendreth. This key was entrusted to Grumbles, who hid it in the area and left a note to remind himself what he did with it. Its location changes based on the note's current text. Possible locations include:
- Next to a lamp post, which sits directly in front of the steps leading to the Castle Nathria raid entrance.
- During early alpha, this item was named Gilded Key.
- Patch 9.0.2 (2020-11-17): Added.
