Are you looking for the Legend or Master Lost Sector locations in Destiny 2? While many Destiny 2 Exotics can be bought from Xûr or even in the world loot pool, the Exotics in these special Lost Sector instances cannot, forcing players to explore these dangerous areas if they want the best equipment available. To make matters worse, you have to complete them on your own to get a chance at the best rewards.
Before you can take on Legend Lost Sectors, you need to complete all the normal Lost Sectors first. If you don’t, the new Legend Lost Sectors will not appear on the map. There are two quests per day in which the location, modifiers, and rewards rotate out for something new. The location for the Legend Lost Sector quests appear with the daily reset at 5pm UTC.
It’s important to remember that Exotic drops are not guaranteed after completing these quests, so you may have to run through the same Lost Sector multiple times. You can go through them quests with a fireteam, but your rewards will be reduced to Enhancement Cores only.
