The Concealed Void Lost Sector is part of a trio of new and revamped missions in Destiny 2: Beyond Light. The Concealed Void Lost Sector rewards some rather interesting stuff. The Concealed Void Lost Sector has a recommended light level of 1210, so use that to know what you’re getting into.
Concealed Void is found within Asterion Abyss, in the middle of the zone. Look on the northern part of the areas, and look for the entrance to the icy underground caves. The easiest way to spot the entrance is to stand near the large outcropping at the center of the above-ground area and look to the west.
Once you head underground, look for the entrance to the right-hand side of the cave, provided you came in the entrance detailed above. Look for the red lights that signal the new entrance. Once you’re inside it’s time to begin.
The first phase of the fight involves taking out waves of mobs while waiting for the energy shield to drop. You need to clear out the trash mobs for that to happen. From there, move inside and complete the Lost Sector.
