The Season of the Worthy in Destiny 2 has brought back a bunch of older content but, has also added a whole load of new content into the shooter. The new batch of post-launch content includes a revival of various mission types as part of the endgame. As players work their way through the quest chains surrounding Warmind Rasputin, you will encounter a variety of different tasks for the factions out among the stars. The Quarry Legendary Lost Sector is one of these missions. This is one of the primary requirements for acquiring the Fourth Horseman, and the quest in Destiny 2 requires that you go for this particular Legendary Lost Sector.
So how do you find this quest? The Quarry Legendary Lost Sector is unlocked via the Seraph Bunker on the EDZ. There is a simpler version of the quest that can be found in the Sunken Isles on the EDZ, but that’s not the one you’re after. Legendary Lost Sectors will often rotate out and the currently active ones will be replaced with different ones every so often. So get the Quarry Legendary Lost Sector while you can.
Legendary Lost Sectors are unlocked as part of the Raising our Defences quest. Head over to Zavala and talk to him. Zavala will send you to visit Ana Bray on Mars. This kicks off a quest chain that involves handing to the Sludge on the EDZ to talk to Rasputin. Once you begin completing the objectives, you will be introduced to the Bunker mechanics and buying your first Bunker upgrade. Once you complete the Raising our Defences quest, you’re ready to take on a Legendary Lost Sector in Destiny 2.
These are very difficult missions that require you to have pretty decent gear with at least 1,000 total Light level to take them on. The Quarry Legendary Lost Sector is pretty tough within this set of missions as the enemies within are actually even harder to take out.
