Quick Answer: To obtain the Gjallarhorn catalyst in Destiny 2, you must complete the "Wolfpack Rounds" quest, which is unlocked after acquiring the Gjallarhorn Exotic Rocket Launcher. The quest involves gathering specific resources and completing activities within the game.

Key Facts

Overview

The Gjallarhorn is one of the most iconic and powerful Exotic Rocket Launchers in Destiny 2, known for its devastating Wolfpack Rounds. Its associated catalyst, also named 'Wolfpack Rounds,' further enhances the weapon's already formidable power by increasing its magazine size and improving the tracking of its cluster missiles. Obtaining this catalyst is a multi-step process that requires dedication and engagement with various endgame activities. It's a sought-after upgrade for any Guardian who wields the legendary Gjallarhorn.

Acquiring the Gjallarhorn Exotic Rocket Launcher

Before you can even think about the catalyst, you must first possess the Gjallarhorn itself. This Exotic weapon was originally a reward from a questline in Destiny 1 and was later reissued in Destiny 2 with the Beyond Light expansion. To obtain it in Destiny 2, players typically need to complete the "Beauty in Destruction" quest, which involves acquiring Exotic Cipher, completing specific activities, and purchasing it from the Exotic Kiosk in the Tower. Ensure you have the necessary resources and have completed the prerequisite quests before proceeding to the catalyst.

The 'Wolfpack Rounds' Catalyst Quest

Once you have the Gjallarhorn equipped or in your inventory, the catalyst quest, officially titled 'Wolfpack Rounds,' will become available. This quest is initiated through a series of objectives that guide you through gathering specific components and completing various in-game challenges. The quest is designed to be a journey, rewarding players for their continued engagement with Destiny 2's core playlists and open-world activities.

Step 1: Gathering Combustion Data

The initial phase of the catalyst quest involves collecting 'Combustion Data.' This data is primarily obtained by defeating Fallen enemies. Fallen enemies are found across various destinations in the game, but they are particularly prevalent in patrol zones like the EDZ, Nessus, and the Cosmodrome. Focusing on activities that feature a high density of Fallen, such as Lost Sectors or specific public events, will expedite this process. The more Fallen you defeat, the faster you'll accumulate the required Combustion Data.

Step 2: Acquiring Wolf Data

The next major component of the quest is 'Wolf Data.' This data is earned by completing matches in Destiny 2's core playlists: Vanguard Strikes, Crucible (PvP), and Gambit. The amount of Wolf Data you receive is typically tied to the success and duration of your matches. Winning Vanguard Strikes, achieving high scores in Crucible, and completing Gambit matches efficiently will yield more Wolf Data. It's recommended to focus on whichever playlist you enjoy most or find most efficient to complete.

Step 3: Collecting Etheric Spiral

A significant portion of the catalyst quest involves gathering 'Etheric Spiral.' This is a planetary resource primarily found in the European Dead Zone (EDZ). Etheric Spiral can be obtained by opening chests and defeating enemies within the EDZ. Patrols, Public Events, Lost Sectors, and general exploration are all effective ways to gather this resource. It is advisable to equip resource-gathering mods on your Ghost to increase the drop rate of Etheric Spiral. Dedicate time to exploring the EDZ thoroughly to collect the substantial amount required.

Step 4: The Final Mission - 'A Hunt'

The culmination of the 'Wolfpack Rounds' catalyst quest is the completion of a specific mission titled 'A Hunt.' This mission is located on the planet Mars. Players will need to travel to Mars and embark on this challenging mission. 'A Hunt' often involves a boss encounter and requires players to utilize their combat skills and teamwork effectively. Successfully completing this mission will finalize the catalyst quest and unlock the Wolfpack Rounds enhancement for your Gjallarhorn.

Benefits of the Wolfpack Rounds Catalyst

Upon completing the catalyst quest and applying it to your Gjallarhorn, you will notice two significant improvements. Firstly, the weapon's magazine size will increase, allowing you to fire more Wolfpack Rounds before needing to reload. Secondly, and perhaps more importantly, the tracking capabilities of the cluster missiles fired by Gjallarhorn will be significantly improved. This means your rockets will be more accurate and less likely to miss their intended targets, especially at longer ranges or against highly mobile enemies. This enhancement solidifies Gjallarhorn's status as a top-tier Exotic weapon for both PvE and PvP content.

Tips for Efficient Catalyst Acquisition

To speed up the process, consider forming a fireteam with friends. This can make completing Vanguard Strikes, Crucible matches, and Gambit matches much faster and more enjoyable. For Etheric Spiral collection, equip your Ghost with the appropriate resource-detecting mods and focus on high-density areas within the EDZ. Pay attention to in-game events and bounties that might align with the objectives of the catalyst quest, allowing you to progress on multiple fronts simultaneously. Finally, ensure your Gjallarhorn is readily accessible in your inventory or vault so you can begin the quest as soon as you acquire the weapon.
