Destiny 2 Duality 2026 Dungeon Guide
The June 9th update brings tiered loot to every raid and dungeon in Destiny 2. Each one will see their weapons get a loot refresh and an individual armor set. The armor sets come with their own set piece bonuses. Duality was once the most farmable dungeon in the game thanks to Artifice Armor. Since that went away, not many have returned.
Duality: Loading Into The Dungeon
After Eris Morn introduces you to the dungeon, you will learn the first mechanic of Duality. You will see a bell on the opposite side of the room. Shooting the bell will transform the realm you are in. It applies to every bell in the dungeon. The bell will transport you between the normal and nightmare realms. One aspect to keep in mind is that if you are in the nightmare realm, you have to stand in the ring around the bell. Shooting the bell, while there, will automatically kill anyone outside the ring.
Run up to the bell and return to the normal realm. Jump up the platforms, killing the Cabal as you go. Once at the top, shoot the bell across from you and return to the nightmare realm. Proceed forward to the next bell. After leaving the bell, turn around and shoot it again. Drop down towards your right to see an open platform. Proceed through and shoot the bell. The path here will lead you to the first encounter. Clear all the Cabal, and the door in the floor opens.
Duality: Nightmare of Galhran
Shoot the bell to start the encounter. You will start in the nightmare realm. A Nightmare Collapsing timer will start. If this timer hits zero, you will die. There are four side rooms in this encounter. In two of these rooms will be Standard Bearer Psions. There will never be a Psion on the same side. For example, if there is a Psion in the top-left room, there will not be one in the bottom-left room. Killing the Psions increases the Nightmare Collapsing timer and drops a symbol. It will be one of:
- Axes
- Sun
- Chalice
- War Beasts
Pick up the standard and search for Honored Bellkeepers. They will always be on the opposite side of the bell. Killing both bellkeepers opens the bell. After you have both standards, run to the bell and shoot it before the timer ends. Have the players with standards deposit in their various places. The deposit spots are:
- Sun – Top Left
- Chalice – Top Right
- Axes – Bottom Left
- War Beasts – Bottom Right
Depositing the standard opens the door in front of you. Some War Beasts and a Colossus emerge. Clear the enemies and have at least one player stand in each door. The third player can join one of them or stay in the middle. Kill the bellkeepers and ring the bell. Players in the room will now face Visions of Gahlran. Kill all of them. After killing all on both sides, the doors open, and the damage phase starts. Deal as much damage as possible to Galhran in the Nightmare Collapsing Timer. If you are running out of time, run to the bell and return to the normal realm. Repeat the process until Galhran dies.
Duality: Second Traversal Section
After Galhran dies, you will return to the normal realm. Pick up your loot and drop down the hole. Run down the path on either the right or left. Once the two sections meet, run through the door. There’s a little bit of parkour here. You will need to activate panels to spawn more platforms. You want to reach the other side and drop down the chute. Turn left and run around to the other side. Keep progressing forward until you reach a large gap. You will need to jump across to the platform and turn right.
You will enter a room with four statues and a bell. Have a player stand by the close, far, and left statues. Shoot the bell to reach the nightmare realm. At the back of each statue is an interactable Calus face. The close statue player should rotate their statue three times. The other two players rotate twice. After successfully rotating, have everyone return to the bell. Ring the bell, and the floor below you will move.
Duality: Unlock the Vault
The standards and bell returns for the second encounter. Before we get into the mechanics, we need to learn where each standard will be. The directions (based on where the rally flag is) are:
- Close right – Chalice
- Close left – Sun
- Far right – Axes
- Far left – War Beasts
When the encounter starts, two standards will show. It will be two of the aforementioned standards. There are bells on either side of the arena. Under the bells are the bellkeepers. As with the first encounter, the bellkeepers tie to the bells on the opposite side. Have one player stand by the standard you need and then shoot the bell. Each player must kill all the Cabal enemies in their section. A Standard Bearer will spawn after they all die. If done correctly, a standard spawns, and your timer increases. If you are incorrect, the timer will shrink.
At this time, the third player should hunt the bellkeepers. Once both players have a standard, return to the bell and ring it. Deposit both standards, and the miniboss will become vulnerable. Kill him, and another miniboss, along with two new standards, spawn. One aspect to note is that, after shooting a bell, it will not be usable until you use the other bell. Repeat the process for the next two mini bosses to complete the encounter.
Duality: Third Traversal Section
After the third miniboss dies, the floor opens. Drop down for your loot and progress forward. You will need to travel in a mixture of the normal and nightmare realms to progress. Most of your traversal is jumping up. Keep an eye out for nooks and crannies that you will need to jump through. After dropping down a chute, you will have some platforms to jump across to reach the final encounter.
Duality: Nightmare of Caital
Learning the position of the standards is important again for this encounter. The positions are not the same as in the previous encounter.
- Close right – Chalice
- Close left – War Beasts
- Far right – Axes
- Far left – Sun
The encounter starts with a bunch of Cabal enemies, including six bell keepers. There are also four bells, three normal ones, and one big one. The fourth bell has the standards surrounding it. Two standards will appear at the start. Have one player stand on the platform with the standard. Teleport to the nightmare realm. Kill the standard bearer and pick up the standard.
As with the previous encounter, killing the right one adds time, and killing the wrong one will wipe you. Kill the four bellkeepers to open up the bell and return. Deposit the two standards, and two more spawn. Repeat the process, and the large bell will light up. Have each player stand near a bell and then shoot the large bell. You will return to the nightmare realm.
The Damage Phase
Kill your bellkeepers as soon as possible. Caital will join you in the realm and will walk towards one of the bells. During this time, Caital can take damage, but it is minimal. Have all players run to the bell she is going to. When she gets close to the bell, shoot it to stun her. You will have a brief period to deal damage. Afterwards, she will run to open the open bells. She does this three times. If you want to slow Caital down, run near her to make her stomp. If Caital does not die in one rotation, repeat the process until she dies.
