TL;DR: The Three Answers
Pick option 2, then option 5, then option 4. That is the full solution to the Data-Altar of Sacred Analysis. Match by number or by the exact lines below, and the sealed wall opens to a chest with an Arc Rifle and the Pinpointing Visor inside.
| Prompt | Pick | The correct line |
|---|---|---|
| First | Option 2 | "...the Omnissiah, from whom the holy discharge springeth forth." |
| Second | Option 5 | "...the arcane key that closeth the circuit." |
| Third | Option 4 | "...the immortal Reason that hath created the spark." |
You get unlimited attempts. A wrong pick costs you nothing, so there is no risk in matching by feel if the menu order ever shifts on you.
What the Data-Altar Actually Asks
The Data-Altar of Sacred Analysis sits inside the Electrodynamic Cenobium, a Mechanicus temple on Rykad Minoris. Interact with it and a servitor leads a call-and-response rite called the First Galvanic Hymn. The servitor speaks a line, you choose how it continues, and you do that three times. Get all three right in sequence and a hidden wall slides open behind the shrine.
This is one of those puzzles where the right answer reads like scripture, not logic. The continuations praise the Omnissiah, name the spark as sacred reason, and treat electricity as a holy circuit. You are reciting Mechanicus doctrine back to the machine, and the machine wants its catechism word for word. That is why we hand you the positions up front. There is no deductive shortcut a first-time player is expected to find, only the correct creed.
If you are reading the menu right now, work from the table above. The line text is the safe anchor because menu order is what matters, and the three quoted continuations are the ones that complete the hymn correctly.
Step by Step Through the Hymn
First prompt. The servitor opens the rite. Choose option 2: "...the Omnissiah, from whom the holy discharge springeth forth." This binds the discharge, the spark of power, to the Omnissiah as its source.
Second prompt. The response moves to the mechanism of the rite. Choose option 5: "...the arcane key that closeth the circuit." The hymn treats the closed circuit as the sacred act, the moment power flows.
Third prompt. The rite resolves on its central claim. Choose option 4: "...the immortal Reason that hath created the spark." Reason is capitalized in-game on purpose. It is being named as a divine principle, not a description, and it is the line that seals the sequence.
Recite all three and the wall behind the altar opens. No timer, no penalty, no second servitor to fight. The whole thing is a dialogue check dressed as a sermon. If you are working through the rest of Rykad Minoris, our full Rogue Trader puzzle solutions cover the other shrines and locked doors in the same run.
What You Get for Solving It
The hidden wall reveals a chest, and the haul is worth the detour. Two unique items headline it.
The Arc Rifle is the prize most players come for. It is a unique ranged weapon that arcs its shot between targets, so it can strike more than one enemy at a time. On Rykad Minoris, an early world, a weapon that hits clustered enemies is a real power spike for whoever you hand it to. Arc damage also pays off in builds that want to soften groups before they close.
The Pinpointing Visor is the other unique, a piece of headgear built around finishing wounded targets. It boosts critical chance against enemies below half health, which turns it into a closer: you set up the hit, the Visor rewards you for going after the low-HP target. Officers and any character feeding off critical hits get the most out of it.
The chest also holds support gear worth grabbing on the way out:
- Carbon-Fibre Plates, an armour kit
- Fire Selector Mods, a ranged weapon modification
- A Magnus-Class Rechargeable Battery
- A Rad-Pack
None of that is build-defining on its own, but free mods and a free armour kit this early stretch a long way, and you are already standing in front of the chest.
Who Should Take the Loot
The Arc Rifle wants a hand that already lives at range and benefits from clearing several bodies at once. The Pinpointing Visor wants a character who can reliably set up the killing blow on low-health targets, which makes the two rewards pull in slightly different directions. That is fine. Spread them across two party members rather than forcing both onto one, and the chest upgrades two slots in one stop.
Because this is an early-game pickup, treat both uniques as bridge gear. They carry well through the first stretch of the campaign and stay relevant longer than most starting equipment, especially the Arc Rifle's multi-target arc, which scales with how often your fights bunch enemies together. If the critical-finisher angle on the Visor appeals to you, our Officer build guide lays out a party built around setting up and cashing in those killing blows.
A Note on Names
Guides and patch threads file this same encounter under a few different titles, so if you arrived searching for the Electrodynamic Cenobium riddle or the First Galvanic Hymn, you are in the right place. All three names point at one puzzle, one altar, and the same answer: 2, then 5, then 4.
