The second weekly mission in Destiny 2: Season of the Deep: “Mayday, Mayday”. dives much deeper into the Titan’s methane seas to find more egregore corals, which will aid Sloane in further communication with the leviathan Ahsa. It’s also shorter than the previous mission, Operation Thunderbolt, and features a much more manageable boss fight. We’ll walk you through how to complete this shorter activity here so you have everything you need to continue the larger seasonal story.

How to complete the Mayday, Mayday. Destiny 2 season 21 mission
First, start the mission from the HELM Director. You start where the previous mission ended: at the first drill site where the Taken portal once led you down. Use the lever on the left side of the airlock to open the door, then clear out the few Hive that appear in the room: the party consists of Thrall, Cursed Thrall, Acolytes, and a lone Wizard.
When the Hive is defeated, head to the airlock in the back of the area and choose which of Ahsa’s gifts you want. Go through the airlock and follow the underwater passageway until you reach a rotating fan at the bottom of a shaft. Land on the platform outside of the fan blades as you will die if you touch them. You can flip another lever under a ladder to turn off the fan and go down.
Keep going through the underwater caves until you reach another door with a lever on the left. Inside is the first arena.
Here you must first defeat three masses of Hive chitin to reveal three fuel cells, which you will then take to a command console at the far left of the arena to power the drill.
Enemies will spawn every time you drop a cell, but they’re a low, fixed number. I used a Warlock build of Sunbracers for the entire activity and had almost no issues, but Solar or Arc Titan, Strand Hunter, or any other add-clear build will do just fine.
After depositing the last power cell, you’ll need to defeat three boss-level Taken Centurions called Wrathful Predators to get the wrenches they can use to fix the drill. You can tell who it is by the bright glow that surrounds them. Pick up the wrenches they drop, defeat any other enemies that spawned with them, and insert the wrench into the machine that spawned where you deposited the fuel cells.
Completing three repairs will spawn a Taken Ogre surrounded by a large group of Taken Thrall, followed by a boss-level Captain called Festering Brute, as well as Taken Vandals and Centurions, and finally a Centurion boss called Furious Intruder. If you take out the last three waves, you will be dragged into the boss room. It’s the same arena as Operation Thunderbolt, but the boss this time is a Hive wizard named Kudazad who is bonded to Xivu Arath.
How to defeat Kudazad bound to Xivu Arath
Fighting Kudazad is much easier than fighting the Servitor J4W-S. I used a linear fusion rifle like the Arbalest, Cataclysmic, Fire and Forget, or another precision power weapon to damage the boss. You can also use rocket launchers like Gjallarhorn, however ammo economy is not that good. Don’t try to craft shotguns like I originally did, as even the Legend of Acrius isn’t appropriate for this encounter.
In the first phase of the fight, the only other threats will be Acolytes and Thrall. So keep moving, but focus on hitting Kudazad whenever possible. Kudazad becomes immune at half health, and two glowing ogres with orange bars appear at either end of the arena. Don’t get up in the open because their eye beams will melt you with ease. Orange bar knights and frag guns will also appear until the boss dies.
At this point, use your Super liberally, and once the Ogres are dead, you can start damaging Kudazad again. The process to defeat him is the same, although the knights may complicate matters. When he falls, collect the coral and the loot chest from the back platform.
