Overview

In Perpetuity is a Triumph in Destiny 2 that requires completing the "The Desert Perpetual" Epic Raid, which released in July 2025. It is worth 25 Triumph score. Raid triumphs such as The Desert Perpetual grant the Atemporal title.

How to complete

Defeat all four bosses of the raid:

1. Iatros, Inward-Turned: a Vex wyvern in a crowded arena. A survival fight with strict timing and a large damage check.
2. Agraios, Inherent: a full-team mechanics fight built on buffs, portal runs and a mobile boss that plays keep-away.
3. Epoptes, Lord of Quanta: the most technical fight, with split squads, shooting the hydra's eyes and symbol matching.
4. Koregos, the Worldline: the final boss, combining Chronon management, plate-based buffs, a vision puzzle and a demanding damage check.

Iatros, Agraios and Epoptes can be done in any order. Koregos must be last.
