Here’s how to get the missing Prismatic Fragments in Destiny 2: The Final Shape : most come from the campaign, hidden chests in the Pale Heart, and Memory quests tied to Light/Darkness vestiges. The fragments tied to Light usually require doing the Alone in the Dark cyst chain, while some Darkness fragments come from overthrow-area chests after collecting vestiges.

Quick Scoop

  • Campaign missions: Several fragments are hidden in story missions, so replaying the campaign steps can fill gaps you missed the first time.
  • Pale Heart chests: Some fragments are in world chests and mission-specific hidden chests around the Pale Heart.
  • Memory fragments:
    • Memory Vestige: Darkness leads to Darkness-related fragments after collecting enough vestiges from bramble/overthrow chests.
* **Memory Vestige: Light** comes from cyst activities in _Alone in the Dark_ , and can unlock Light-related fragments like **Facet of Dominance** , **Facet of Awakening** , and **Facet of Generosity**.
  • Account-wide unlocks: Fragment progress is account-wide, so once unlocked, it applies across characters.

Fastest fix

  1. Finish or replay the Final Shape campaign.
  1. Do the Pale Heart side adventures and hidden chest routes.
  1. Run Alone in the Dark cysts for Light vestiges if your missing fragments are the Light Memory ones.
  1. Farm overthrow/bramble chests for Darkness vestiges if you still need those fragments.

What players usually miss

  • Hidden mission chests in the campaign.
  • The second half of some Pale Heart adventure chains.
  • Light Memory fragments because the cyst step is easy to skip or do out of order.

Community shorthand

A lot of players summarize it like this: story missions for some, Pale Heart exploration for some, then Light/Dark memory grinding for the last ones.

TL;DR: Check campaign mission chests first, then Pale Heart adventures, then farm vestiges from overthrow chests and Alone in the Dark cysts for the remaining Memory fragments.
