Mind Heist

Overview

Mind Heist is a Triumph in Destiny 2 worth 10 Triumph Score. It is earned by collecting all twelve of Calus's Repressed Memories hidden in the Duality dungeon, across both the normal and Nightmare realms.

How to complete

Collect all twelve Repressed Memories. Locations below are from the Duality dungeon walkthrough, with the realm noted where it matters.

1. Normal realm, first large room: at the top of the room, in an open door on the right side, past the bell.
2. Nightmare realm, first large room: same spot as the first memory. Face the bell and enter the open side room on the right.
3. Nightmare realm, after the second memory: drop through the internal wall, then look behind the pillars for a container on a platform near the breaking ship.
4. Before the Nightmare of Gahlran: on the roof of the semi-circular structure in the chandelier room. Use the door frames to climb.
5. Nightmare of Gahlran, War Beast room: collect during or after the fight, and avoid dropping down the hole.
6. Tomb room: activate the second lever, then go left instead of right. Look for a high hole in the wall.
7. Chasm before the spinning statue room: drop down instead of jumping across to find a hole in the wall.
8. Nightmare statue room: behind the large pillar that holds the bonus chest in the normal version.
9. Vault encounter: on top of a tomb, up and to the left when facing the stairs to the bell.
10. Block room, normal: under the central block covered in white cloth. A bonus chest is also here.
11. Block room, Nightmare: at the top of the room, through the large open door and down the hallway. Use the pillar platforms to get back on track.
12. Above the Nightmare of Caiatl door: use the platforms to the right of the door, or jump from the slanted platform.

Rewards

Collecting all twelve increases your chance of getting Heartshadow, an Exotic sword. Claim the triumph before defeating Caiatl.
