How to Get Gjallarhorn in Destiny 2: And Out Fly the Wolves Quest and Catalyst Chests

Gjallarhorn is the most famous gun in Destiny history, and it's still one of the most searched-for Exotics in Destiny 2. The good news: it's not a random drop. You earn it through a fixed quest, And Out Fly the Wolves, built around the Grasp of Avarice dungeon. Once you have it, a second trip through the dungeon unlocks its catalyst.

This guide is up to date for the current version of the game in November 2026. Even after The Edge of Fate replaced the old Director with the Portal and the World map, Gjallarhorn's source is still the same quest.

Quick answer

In short: own the 30th Anniversary Pack, run Grasp of Avarice, farm Wolfpack Rounds in the Cosmodrome, clear Exodus Garden 2A and build the launcher at Shaw Han's camp.

Requirements

• The Bungie 30th Anniversary Pack. Both the quest and the Grasp of Avarice dungeon are tied to it. Grasp of Avarice doesn't need a separate Dungeon Key.
• A fireteam of up to three, or a solo plan. Grasp of Avarice is a dungeon for up to three players with no matchmaking, so bring friends or find a group if you don't want to solo it.
• A couple of hours. One dungeon run, a short farm and two Lost Sector clears.

Launch Grasp of Avarice from the Cosmodrome on the World map, the screen that replaced the old Director. Dungeons and raids sit in their destinations there.

Step-by-step: the And Out Fly the Wolves quest

1. Start the quest with Shaw Han. Head to the Cosmodrome and talk to Shaw Han at his camp. When the quest launched in December 2021, it was picked up from Xûr in his Treasure Hoard before you met Shaw Han, so look there if he has nothing for you.
2. Run Grasp of Avarice. Shaw Han sends you to the loot cave at Skywatch, which leads into the dungeon. Any difficulty counts. Clear it and loot the final chest to get your first Wolfpack Round.
3. Report back to Shaw Han. He asks for more Wolfpack Rounds.
4. Farm Wolfpack Rounds. You need seven in total, so six more after the dungeon. They drop from powerful Fallen, the enemies with yellow health bars, in the Cosmodrome. The quickest spot is the Exodus Garden 2A Lost Sector in The Divide, close to Shaw Han's camp. Repeat it until the counter is full.
5. Return to Shaw Han, then visit Banshee-44. Hand in the rounds, then travel to the Tower and speak to Banshee-44, the Gunsmith. He points you back to Exodus Garden 2A for the last part.
6. Clear Exodus Garden 2A again. Beat the Lost Sector boss and open the end chest to grab the final component.
7. Assemble Gjallarhorn. Go back to Shaw Han's camp and enter the building on the ground floor opposite him. Interact with the tool chest to put the rocket launcher together.
8. Talk to Shaw Han one last time. He hands over Gjallarhorn and the quest is done.

Step-by-step: the Gjallarhorn catalyst

The catalyst comes from three hidden chests in Grasp of Avarice. Each one only opens while you carry the Burdened by Riches debuff, which you get by picking up a special engram dropped by a nearby Reaver Vandal. The debuff is on a timer, and if it runs out, it kills you, so plan the route before you grab the engram.

1. Chest 1 – the loot cave. After you drop into the cave, look for the Reaver Vandal across the cavern. Damage it, take the engram and open the chest on the raised platform.
2. Chest 2 – near the first boss. After the rolling barrel trap and the red-lit staircase, a Reaver Vandal waits in the next room. Take its engram, go through the air vent and find the chest tucked into a corner on the platform to the right.
3. Chest 3 – the Fallen Shield encounter. Get the engram from the Reaver Vandal on the waterfall island, then climb the structure on the central island to reach the chest.
4. Finish the dungeon. Once all three chests are open, complete the run to receive the catalyst.
5. Get 400 kills with Gjallarhorn. That completes it. The catalyst bumps the magazine to two rockets, and final blows with Wolfpack Rounds spawn a faster, more powerful missile.

Tips

• Run it on normal first. The quest only asks for a clear, so save Master difficulty for later.
• Farm Wolfpack Rounds and the final part in one trip. Exodus Garden 2A covers both, so you'll get used to the route.
• Hold off on the catalyst until the quest is finished and Gjallarhorn is in your inventory.
• Let one player carry the debuff. In a fireteam, the person nearest the chest should grab each engram.
• Note your Wolfpack Round count between runs. The quest tracker shows how many you still need, so you won't run the Lost Sector more often than necessary.

Common mistakes

• Trying to farm Gjallarhorn as a drop. It never drops from the dungeon's chests. The quest is the only way to get it.
• Killing the Reaver Vandal too far from the chest. The Burdened by Riches timer starts as soon as you pick up the engram, and it's lethal if it runs out.
• Leaving the dungeon before the end. The catalyst is awarded at the end of the run, so finish it after opening the third chest.
• Looking for the dungeon in the wrong place. Dungeons launch from their destination on the World map, so open it and select the Cosmodrome.
• Skipping the workbench. After the last Lost Sector, the launcher has to be built at the tool chest before Shaw Han will hand it over.
