Space Marine 2 Armoury Data Farming Guide: Fastest Route to Relic Weapons

Armoury Data in Warhammer 40,000: Space Marine 2 is the single currency that unlocks weapon tiers across three rarities—Master-Crafted, Artificer, and Relic—and the biggest farming mistake players make is not understanding that Relic is a rarity tier, not a separate resource. This guide covers which difficulty drops which rarity, the Data Refinement trade-up system, how to hunt Terminus bosses for bonus drops, and how to survive a full Ruthless run so you can extract with your hard-earned gold-tier data intact.

Armoury Data in Space Marine 2 comes in three rarities: Master-Crafted (green), Artificer (purple), and Relic (gold). Each rarity corresponds with the weapon tier of the same name, so you need one Relic Armoury Data plus the required weapon XP to unlock the Relic tier of any weapon type. The most common misconception is treating Relic as a separate currency—it’s just the top rarity of the same resource you’ve been collecting since your first Operation. Each weapon type has four rarity tiers which you must unlock by earning increasing amounts of XP in Operations and by spending one Armoury Data of the same rarity. Developed by Saber Interactive and published by Focus Entertainment, Space Marine 2 gates your weapon progression behind difficulty, making Armoury Data the most important farmable resource in Operations mode.

Armoury Data comes from two PvE modes: Operations and Siege. In Operations it drops from a hidden Servo Skull or from killing a Terminus-level boss that can attack at random. Siege pays out on a fixed schedule instead of a random one — clearing Wave 10 grants three Master-Crafted on Normal (Artificer on Hard), and Wave 20 grants three Artificer on Normal (Relic on Hard). Neither the campaign nor PvP awards any Armoury Data. Servo Skulls are small floating skulls with wires coming out of them that can appear in odd places, like dead-end corridors. If you find a Servo Skull and successfully finish the mission, you will get an Armoury Data point, the rarity of which will depend on the mission’s difficulty; the same rarity distribution applies to Terminus boss kills if you defeat one and successfully extract. You can also achieve an A-rank in training Trials to get one Master-Crafted Armoury Data per Trial; every class has three Trials in the Armouring Hall, so a full sweep across the roster is a one-off chunk of Master-Crafted Data without entering a mission — Trials cannot be repeated for more.

The difficulty you select determines which tier of Armoury Data you receive from both Servo Skulls and Terminus boss kills. Higher difficulties don’t award more data per drop—they award higher rarities, which unlock better weapon tiers.

A post-launch update added a Data Refinement system; you can find a Tech-Priest on the right side of the room in the Armouring Hall who allows you to trade in lower-level Armoury Data for higher levels, at a rate of 3 of the lower level for one of the higher. Three green Master-Crafted can be exchanged for one purple Artificer, and three purple Artificer can be exchanged for one golden Relic. This is the mechanic most players miss. If you’re farming Master-Crafted data on Average difficulty, you need nine green data to craft one Relic via two refinement steps—an inefficient path compared to a single Ruthless Servo Skull find. This is a great addition as it allows people to level up their weapons and get better versions without the need to grind the game’s highest difficulty levels first; instead, you can get your weapons upgraded first, then take on the tougher challenges.

Tyranid Terminus Bosses

Defeating Terminus-level boss enemies such as Carnifex or Neurothrope can reward you with Armoury Data for that difficulty. The Carnifex is the armoured Tyranid behemoth you’ll recognize by its scything talons and charging attacks; the Neurothrope is the alpha psychic variant of the Zoanthrope, floating with a visible energy shield. You’ll know that a Terminus enemy is present nearby when a full health bar at the top of the screen shows up during a mission (excluding the Hive Tyrant); so far, only one random Terminus boss is likely to show up in each Operation mission, and chances are higher the tougher the difficulty.

Chaos Terminus Bosses

Helbrute is the Chaos Terminus-level boss that can reward Armoury Data for that difficulty. The Helbrute is a Dreadnought-class enemy wielding heavy weapons and melee attacks; treat it like a Carnifex in terms of threat level. As of July 2026, Patch 14 is testing a Scarab Occult Terminator Sorcerer as a new Chaos Terminus on the Public Test Server, but that boss is not live yet.

Spawn Rates and Expectations

Only one random Terminus boss is likely to show up in each Operation mission, and chances are higher the tougher the difficulty. On Substantial and Ruthless difficulties, you’re almost guaranteed to encounter a Terminus-threat boss. Do not expect guaranteed Terminus spawns every run on lower difficulties—the Servo Skull is your reliable source, while the Terminus is a bonus. Absolute difficulty has the potential for more data based on Terminus spawns; double Terminus can spawn and can spawn on boss operations.

The math is clear: farming one Servo Skull on Ruthless gives you one Relic Armoury Data. Farming nine Servo Skulls on Average and refining them twice (nine green → three purple → one gold) gives you the same result but takes at least nine successful Operations instead of one. Ruthless mode enemies have high stats and are very aggressive; without Artificer-tier weapons and a fair number of class and weapon perks, these missions are quite difficult, but Terminus-tier bosses and Servo Skulls both reward you with Relic-tier Armoury Data, giving you access to the best weapons in the game. The difficulty jump from Substantial to Ruthless is less punishing than the jump from Average to Substantial, so once you have purple weapons, Ruthless becomes the most efficient farm. Data Refinement is a safety net for players stuck between tiers, not the optimal path.

A wipe on the final objective costs you the entire run’s Armoury Data, so extraction discipline matters more than kill speed. If you’re farming Ruthless solo or with AI squadmates, prioritize contested health recovery over greedy damage windows—every parry and gun-strike restores your health bar, so learn enemy parry timings instead of facetanking. Bring a class with self-sustain or crowd control: Bulwark’s banner provides team survivability, Heavy’s area denial controls space, and Vanguard’s grapple hook offers escape tools when overwhelmed. Ammo is scarce on Ruthless, so memorize ammo cache locations and don’t waste ranged fire on Minoris-tier enemies you can gun-strike for free. The last third of most Operations is where runs fall apart—if your squad is low on health and ammo before the final wave, slow down and clear safely rather than rushing the objective trigger.

Myth: Relic Data Is a Separate Currency

Relic is not a different resource—it’s the gold rarity of Armoury Data. There are three tiers of Armoury Data: Master-Crafted (green), Artificer (purple), and Relic (gold). You don’t farm “Relic Data” and “Armoury Data” separately; you farm Armoury Data, and the difficulty determines whether it drops as green, purple, or gold.

Myth: You Can Farm Data in Campaign or PvP

Armoury Data comes only from PvE: Operations and Siege. The campaign awards none, and PvP (Eternal War) pays XP and Requisition but never Armoury Data. The campaign does not award Armoury Data, and PvP (Eternal War) gives you XP and Requisition but not the data you need for weapon tier unlocks. If you want any tier of Armoury Data, you must play Operations.

Myth: Data Drops Even If You Fail the Mission

If you find a Servo Skull and successfully finish the mission, you will get an Armoury Data point. The key word is “successfully”—if your squad wipes before extraction, you lose the Servo Skull and any Terminus drops from that run. You must complete the Operation to bank the data, so don’t overextend on the final objective if your team is already holding one or two pieces of data.
