History of Thoughtstealer

Overview

Thoughtstealer is the Duality completion Triumph. Finish the dungeon to earn 40 Triumph score and The Deepest Truth emblem. It also appears in the Moments of Triumph 2022 records.

How to complete

Obtain access through The Witch Queen Dungeon Key and start Duality after collecting A Single Thread from Suraya Hawthorne. Use Bells of Conquest to move between Calus's mindscape and its nightmare counterpart. Stand near the bell when returning from the nightmare realm; being outside its safe area is fatal.

Defeat Nightmare of Gahlran, Sorrow Bearer by collecting standards and clearing the side rooms. At the vault, collect the standards matching its displayed symbols and deposit them to expose each miniboss.

At Nightmare of Caiatl, Princess-Imperial, collect and deposit the required standards, then activate the central mechanism. Follow Caiatl to her chosen bell, defeat its Bellkeepers, and ring it while she is nearby to stun her for damage. Repeat until the boss is defeated and the dungeon completes.
