Bleak Watcher

Overview

Bleak Watcher is a Stasis Aspect for the Warlock Shadebinder subclass, and Prismatic Warlocks can equip it too. Holding the grenade input converts the grenade into a turret that fires slowing projectiles at nearby enemies. Equipping it unlocks two Stasis fragment slots, or three Prismatic fragment slots. It requires Aspect of Influence to be equipped first. Bungie's March 2021 known-issues list also called it a Stasis turret.

Unlock

Bleak Watcher is unlocked by completing the quests Aspect of Destruction and Aspect of Influence, both offered by the Exo Stranger on Europa.
