Destiny 2 Season of the Seraph: More Than a Weapon Full Guide

Master the Destiny 2 More Than A Weapon quest in Season of the Seraph: all steps for Hierarchy, Heist Battlegrounds, and Seraph Key Codes.

Let me be honest: Destiny 2’s Season of the Seraph was one of those seasonal storylines I didn’t fully appreciate until I ran it again. The More Than A Weapon quest chain is the main thread, sending you across Europa, the Moon, and the H.E.L.M. to recover Rasputin’s lost Warmind Subcells before Xivu Arath gets her claws on them. If you want the whole story and the rewards, I’ll walk you through every step.

Complete the Hierarchy Mission

This mission kicked off automatically the first time I logged in for the season. It drops you on Europa to convince Clovis Bray to help restore Rasputin from his Engram. Immediately, you’ll meet the season’s signature headache: detection beams that trigger devastating lasers if you wander into them. I learned quickly that caution beats speed here.

Once you slip inside the Braytech facility, expect Xivu Arath’s minions and their Cryptoliths. Clear the room, then deal with Aethiks, Instrument of Xivu Arath. This fight isn’t too brutal if you keep moving, but don’t let the adds pile up.

Deeper in, you’ll run into Deathtongue Speakers. These enemies sprint toward Totems of Xivu Arath and start a song that suppresses your abilities and buffs the enemy. I made it a rule: kill them immediately, no exceptions. Clear all enemies to unlock the next door.

The mission then turns into a platforming descent. Be patient with the jumps, because dying to a missed ledge is embarrassing, but we’ve all done it. At the bottom, you’ll fight Techwizard Malykuh, Salvation's Warden. Once the boss falls, Osiris and Ana Bray arrive, and you’ll return to the H.E.L.M. to set up the Exo Room and grab the Seraph Cipher artifact.

Step 1: Speak To Mara Sov At The Holoprojector

After unlocking the Exo Frame room, head to the Holoprojector near the entrance. Mara has intel about Xivu Arath’s plans, and it sets the tone for the next few weeks.

Short, simple, but necessary. Don’t skip it or the quest won’t advance.

Step 2: Complete Heist Battleground: Moon

Now you’re raiding a bunker to recover a Rasputin Submind cell. This Heist Battleground is not a chill patrol. Bring your best PVE build, because the enemy density can get spicy. You’ll fight through Hive forces, crack open the bunker, and extract the cell.

Step 3: Collect Seraph Key Codes

Seraph Key Codes drop from activities across the system, but ritual playlists are the fastest source. I found the Crucible, Vanguard, and Gambit playlists gave me a steady stream while I was already working on weekly challenges. You need 500 for the next step, which sounds like a lot but goes quickly if you multitask.

Step 4: Spend Seraph Key Codes To Unlock A Seraph Chest

This step forced me to respect the difficulty. You need to complete a mission from the Battleground: Heist playlist and open the extra chest at the end. Enemies spawn at five levels above your Light Level, and the mission feels like a Hero Nightfall. Bring Anti-Barrier and Anti-Unstoppable mods, plus a dedicated PVE setup. I’ll say it plainly: don’t waltz in with a half-baked loadout.

Step 5: Complete The Mission Operation: Archimedes

This is a soloable mission to secure the Warsat Launch Facility. You’ll start outside and need to avoid the defense beams as you work around to the left. Inside, you must restore power by killing Arc-Charged Knights and grabbing the Arc-Charges they drop.

The final fight is against Sumak, Ravager of Torobatl, an Ogre with an invulnerable shield at 50% health. To break it, kill the knights that spawn and stand in the green circles they leave behind. While inside a circle, you can damage the boss through the shield. I wiped once because I didn’t realize the circles were a damage buff zone, not just decoration. Don’t be me.

After clearing the room, pick up the final charge from the Ogre and restore power. Then it’s back to the H.E.L.M.

Steps 6-9: Wrapping Up Week 1

These final steps are mostly dialogue and a holding pattern.

• Step 6: Speak to Ana Bray at the Holoprojector.

• Step 7: Speak to Clovis at the Exo Frame for updates and rewards.

• Step 8: Listen to the radio near the Holoprojector for a conversation between Ana and Osiris.

• Step 9: Continue to Retrieve Data, which is the weekly stopping point.

Step 9 is basically your sign to relax until the next weekly reset. If you’re running this in 2026 as a returning player, don’t stress about lockouts. The quest steps still follow the same path, so just pick up where you left off and enjoy the story.

My tips for a smoother run

Tip	Why it helps
Bring Champion mods early	Anti-Barrier and Anti-Unstoppable are non-negotiable in Heist Battlegrounds
Use a solar or void build with recovery	Survivability matters when enemies outlevel you
Don’t ignore Deathtongue Speakers	They will ruin your ability uptime
Open the extra chest during Step 4	If you forget, you’ll need another run

That’s the full Week 1 route for More Than A Weapon. It’s a lot, but once you understand the cadence, it feels like a proper Season of the Seraph operation: tense, story-rich, and rewarding.

According to coverage from GameFAQs, community-made walkthroughs and Q&A threads often emphasize the same pain points your Week 1 “More Than A Weapon” route highlights—namely, treating Heist Battlegrounds like high-pressure PvE (champion counters and survivability first) and prioritizing time-sensitive targets such as Deathtongue Speakers before they suppress your kit. That player-sourced perspective reinforces why steps like farming Seraph Key Codes efficiently and remembering the bonus Seraph chest are less “busywork” and more the difference between a clean weekly clear and an extra rerun.
