All four of Destiny 2's Moon Lost Sector were added to the Legendary Lost Sector pool in Season of the Chosen. These Lost Sectors are longer than most and are packed with enemies. Completing these on Master difficulty will be no small feat.
K1 Communion can be frustrating at times. While only one shielded enemy exists in this entire Lost Sector, you'll need to deal with some of the toughest Champion types in the game. Bring some good Champion counters, and you should be able to clear this on Master without much trouble. Here is a complete guide to the K1 Communion Master Lost Sector in Destiny 2.
Updated September 9th, 2022, by Charles Burgar: Artifact mods have changed with Season of the Plunder, encouraging you to switch your loadouts. While K1 Communion hasn't changed, your Champion counters have. We've updated this guide with new loadout recommendations to reflect seasonal mod changes.
Modifiers And Recommended Loadout
K1 Communion focuses more on throwing dozens of adds at you than utilizing shielded foes or Champions. As long as you can quickly dispatch hordes of Fallen, this Lost Sector should give you little trouble. Here's what you're up against:
K1 Communion Modifiers
Recommended Loadout
K1 Communion: Entrance
Entrance Enemies
- One Overload Captain
- One Barrier Servitor
- Vandals
- Dregs
- Shanks
Right as you enter the first room, pay attention to your right; an Overload Captain will push you when it detects you. Before you kill the Captain, kill any Vandals in the room. Once defeated, focus on the Overload Captain before you defeat the Dregs. If you don't, a Barrier Servitor will spawn and make the Captain invincible.
Overload Rounds affect Champions while they're immune or recovering from a stun. Right as an Overload Captain gets up from being stunned, shoot an Overload Round into them to delay its health regeneration and prevent it from teleporting.
When the Vandals and Captain are dead, a Barrier Servitor will drop from the ceiling alongside a few Fallen enemies. Take down its shield from the back of the room, using your anti-Barrier weapon or freezing them with Stasis to do so.
Once all the enemies are dead, push into the hallway. Take down the handful of Dregs and Shanks, then proceed to the next arena.
K1 Communion: Underground
Entrance Enemies
- One Overload Captain
- Two Barrier Servitors
- Vandals
- Dregs
- Shanks
- Wretches
Directly below you will be an Overload Captain, a few Shanks, and some Dregs. Focus on the Overload Captain first, disrupting it from a distance before unloading your Heavy ammo into it. Destroy the Shanks, then drop down to find some cover. Wretches will push you directly across from the entrance. You can either jump back up for cover or immediately flush the enemies out with a grenade.
Across the arena will be a Barrier Servitor and a band of Fallen Vandals. These enemies can one-shot you if you're underleveled, so keep your distance. Solar Ignites or long-range precision weapons should take care of the Vandals. If they're immune, break the Barrier Servitor's shield to remove the immunity tethers. Kill the snipers, then destroy the Servitor.
When most of the enemies are dead, an additional wave of Fallen will spawn. In this wave will be a Barrier Servitor. Once again, destroy the Servitor before you deal with the adds. If you're running Stasis, now is a good time to freeze the Barrier Servitor to deal with the adds. Stick to the back of the room, pick off the enemies, then grab any ammo bricks on the ground before proceeding.
K1 Communion: Corridor
Corridor Enemies
- Two Overload Captains
- Marauders
- Vandals
- Dregs
- Wretches
Two Marauders will guard the entrance to a long corridor. Right past those two enemies will be an Overload Captain. Kill the Marauders, get the attention of the Captain, then double back to the entrance. Stun the Champion with your Overload weapon, then take him down with a Heavy weapon.
In the next room will be yet another Overload Captain alongside Vandals and Dregs. A grenade or a rocket works wonders here, clearing out most of the enemies. Once again, stun the Champion before killing him. Clean up the enemies in the next room. A few Wretches will spawn when you reach the end of the corridor, nothing your Primary or an AoE attack can't handle.
K1 Communion: Boss Arena
Boss Arena Enemies
- Two Overload Captains
- Two Barrier Servitors
- One Captain Boss
- One Heavy Shank
- Shanks
- Tracer Shanks
- Explosive Shanks
- Dregs
- Vandals
- Wretches
- Marauders
Things are going to get tough in this final arena. Feel free to use your Super, Heavy ammo, whatever it takes to stay alive.
Right as you enter the final room, an Overload Captain will rush you. Focus on taking it down as fast as possible, then direct your attention to the Vandals. Once defeated, take out the second Overload Captain at the end of the room. This room will also have a Heavy Shank with a Solar shield, so be prepared to destroy it. Killing most of the Fallen in this room will activate an alarm system, turning the room red while spawning a boss.
Don't damage the boss until you've dealt with the adds. Kill most of the Fallen in the room, then find a safe spot to damage the boss from. When the boss loses a third of his health, a Barrier Servitor will spawn. It is imperative you take this Servitor out. Try to keep your distance while fighting it, avoiding as many projectiles as possible. Kill the Champion, then the Fallen adds, then the boss.
When the final boss has lost 66% of his HP, an additional Barrier Servitor will spawn on the other end of the room. Move to a safe location and damage from a distance. Kill all of the adds before killing the boss.
One final wave of Fallen will spawn when the boss is on the brink of death. While no Champions spawn, a torrent of Explosive Shanks will appear. Double back to the entrance, picking them off one by one. Clean up the remaining enemies, then claim your loot. You'll know the coast is clear when the red lights stop flashing.
