Memory Vestiges

Overview

Memory Vestiges (Light and Darkness) are consumables from The Final Shape used to forge Memories. Collect five of the same type and they automatically forge a Memory of that type, which marks a Prismatic Fragment chest in the Pale Heart. A Memory is used up when you open its chest.

Memory Vestige: Light

Memory Vestige: Light drops from powerful enemies inside the cyst caves of the Pale Heart. Only the cyst tied to your current Micah-10 'Alone in the Dark' quest drops it, and other cysts do not. Once you complete that quest, its cyst stops dropping the currency, so you need the next quest and its cyst. The quests become available after the Final Shape campaign.

Start the quest, advance to the cyst-clearing step, and kill the powerful enemies without finishing the cyst. Every five Vestiges convert into a Light Memory. If the drops stop at four, return to orbit and re-enter the cyst.

You need at least 15 Memory Vestige: Light to unlock all the Prismatic Fragments that use it. Once those are unlocked, enemies stop dropping it.

Memory Vestige: Darkness

Memory Vestige: Darkness comes from corrupted pyramid chests covered in Darkness brambles around the Pale Heart. Interact with a chest to start a 90-second cleansing challenge. The challenge depends on the patrol zone and the chest's verb, such as stitching, expunging or offering. Examples include killing enemies in Light pools, a Sparrow race, or escorting a bramble ball to a plate. If you fail, restart it. Open the cleansed chest to claim the Vestige.

Memories

• Light: Refraction of Light (The Refraction), Seclusion of Light (The Seclusion), Blooming of Light (The Blooming).
