The Desert Perpetual Raid Guide: Every Encounter and Koregos

The Desert Perpetual is Destiny 2's newest raid, released with The Edge of Fate in July 2025. You pick the first three bosses in any order: Epoptes, Iatros and Agraios. Clearing all three unlocks the final boss, Koregos, the Worldline. Every fight is about the same skills: split into small teams, read buffs, bank Chronons and make clear callouts.

This guide explains how each encounter works, what every team does and how to prepare. It is current as of October 2026, after Monument of Triumph (update 9.7.0), which Bungie released in June 2026 as its final live content update. See your clears and fastest times for every raid and dungeon on the RankSurge Destiny 2 stats page.

How does The Desert Perpetual work?

The raid has no fixed order. In the opening area you choose one of three interactables, and each prompt leads to a boss, per Shacknews and The Game Post. Enemies in the opening area do not have to be killed, per Kyber's Corner.

Normal difficulty needs 100 Power, per Kyber's Corner. Shacknews suggests starting with Epoptes, because it is the most technical fight.

How do you beat Epoptes, Lord of Quanta?

Epoptes is a communication check. Clear the adds until two Time Magistrate Cyclops spawn and kill both. Pairs then stand on side plates to gain Constant Temporality, a short buff that lets them break eyes. Two Inside Readers go into the side rooms and shoot the shield eyes that the Outside Readers in the middle call out. Breaking the shields lets the team shoot the Flashlight eye and start damage, per The Game Post.

• Inside Readers (2): enter the side rooms and shoot only the called eyes.
• Outside Readers (2): read the eyes from the middle and call them clearly.
• Ad clear (2): keep the middle safe and kill the Cyclops fast.

How do you beat Iatros, Inward-Turned?

Iatros is about keeping the clock alive. Vex Minotaurs drop Chronons that you bank in the Hourglass to add time. As you bank, players build Diastole stacks; at four stacks they are launched. Players shoot Vex boxes at the pillars to build platforms, and one climber with Absolute Temporality climbs and interacts with a small cube at the top of each set. Damage lasts only seconds, so a runner keeps killing Minotaurs and dunking Chronons during it to stop a wipe, per The Game Post and Shacknews.

How do you beat Agraios, Inherent?

Agraios splits into three versions: made Cyclical, made Absolute and made Constant. Three players stand on the matching plates (left Cyclical, middle Absolute, right Constant) and bring their buff under the boss with the same name. The rest of the team kills the Vex Hydra and Minotaurs and delivers their Chronons to charge the Accelerator rings. A runner passes through the rings to charge a special grenade that blocks the boss's shot and starts damage, per The Game Post and Shacknews. Each pass through the rings again extends the phase.

How do you beat Koregos, the Worldline?

Koregos uses everything you learned. The fight starts with a timer. In the lower phase, players with the Constant, Cyclical and Absolute buffs share what each one can see: Constant players see mine colors, Cyclical players see which mines are active, and the Absolute player reads the color of the central ring, per Shacknews. Shoot the right mines and turrets, bank Chronons into the Hourglass, then move to the upper phase.

In the upper phase, cube interactions start damage and the boss's eyes become crit spots, while one player keeps dunking Chronons to extend the phase. Watch for lasers and Arc pools. The Game Post adds that when Koregos dies a short timer starts and everyone must leave the boss platform, so move as soon as the kill lands.

What changed for raids in 2026?

Bungie released Monument of Triumph (update 9.7.0) on June 9, 2026, after which Destiny 2 receives no more planned live-service content updates, per Bungie Help. Raids and dungeons can now be launched from the new Raids and Dungeons node or Pinnacle Ops. Per Kyber's Corner, it changed raid rewards:

• Featured rotation: two featured raids and two featured dungeons each week give the best rewards.
• Feats moved: Standard difficulty no longer needs Feats for weekly top-tier rewards; Feats now live in a Custom difficulty with extra rewards.
• Older raid gear: pre-Edge of Fate raid and dungeon gear now comes in tiers, and raid and dungeon Exotic weapons are farmable.

Check the weekly reset before you plan a run. For example, Vow of the Disciple and Last Wish were the featured raids for October 13 to 20, 2026, per Kyber's Corner.

How do you prepare your fireteam?

• Assign roles before you load in: readers, runners, climbers and plate players. Most wipes are a role nobody took.
• Agree on callouts: use the same names for eyes, plates and colors every attempt.
• Bring two loadouts: one for add clear and one for damage. The Destiny 2 Vault Manager lets you save and equip loadouts between encounters.
• Check your Power: our guide to Destiny 2 Power level explains caps and how to climb.
• Find a team in your clan: the clan board in our Destiny 2 clan stats guide shows who has the most PvE clears.
