The Finals Shape expansion for Destiny 2 introduced the Prismatic subclass, which lets you mix abilities, Supers, Aspects, and Fragments from other subclasses. To unleash Prismatic's full potential, you'll need to unlock every element as quickly as possible.
ALL Prismatic FRAGMENTS, Aspects and Skills Unlocked (ANY LOCATION) | Destiny 2 The Final Shape
A subclass can’t function without its Aspects, and while you’ll gain a few throughout The Final Shape campaign, they might not be enough to create your perfect build. Here’s how to unlock every Prismatic Aspect in Destiny 2.
During The Final Shape campaign, you'll have access to three Prismatic Aspects, including a new Aspect for each class. To unlock the rest, complete The Final Shape campaign (not counting the eighth mission) and start the Destined Heroes Exotic quest.
The sixth step of the Destined Heroes is to obtain and complete two quests: Lost in the Light and Found in the Dark. You can pick up these quests at your Ghost in The Pale Heart destination.
