TL;DR
The "navigator puzzle" is the laboratory you hit while hunting for a replacement Navigator on Eurac V. Solving it is part of recruiting Cassia Orsellio. The fastest clean clear:
- Walk to the Transducer across the room and convert Psy-Crystal into Crystal Dust before you touch any slot.
- Load the console: Tissue Flask = Mutated Flesh Sample, Catalyst Flask = Biogel, Reagent Flask = Crystal Dust, Data-Crypt Connector = Data-Crypt H-41-OK. Press the central button to mix.
- Reward: Adaptive Antidot x6 (immunity to toxic damage, with a -10 Toughness penalty until the end of combat).
Match a recipe exactly. A wrong combination makes the machine explode, and you only get one good attempt.
Why you are standing in this lab
You came to the Navis Nobilite station looking for a Navigator. The voidship needs one, and this is where you find item:cassia, the companion who fills that seat. The station sits on the satellite Eurac V in the Rykad System, during Act 1, and the questline that runs through it is "Secrets of the Navis Nobilite."
The lab gates your progress. You cannot just walk past the research console, and the puzzle ships with no instructions, so most players reach it, poke at the four slots, and get nothing. That is the moment people start searching for a "navigator puzzle" answer. Here it is.
The one mistake that ruins the run
The console has four slots: Tissue Flask, Catalyst Flask, Reagent Flask, and the Data-Crypt Connector. You drag an item onto a tube, and a correct match lights the slot with a green background.
Three of those slots take an item straight from your inventory. The Reagent Flask is different. It refuses every raw mineral you own. It only accepts a powdered component, and the only way to get powder is the Transducer.
That single fact trips up almost everyone. Players try to jam Psy-Crystal or Adamantine directly into the Reagent Flask, the slot rejects it, and they assume they are missing an item. They are not. They skipped a step.
Use the Transducer first
The Transducer is a separate device across the room from the console. Feed it a mineral and it grinds out the matching dust:
| Feed in | Get out |
|---|---|
| Meteorite Chunk | Meteorite Dust |
| Psy-Crystal | Crystal Dust |
| Adamantine | Adamantine Dust |
For the recommended recipe, you want Crystal Dust, so put the Psy-Crystal through the Transducer. Do this before you start filling slots and the Reagent Flask will accept the dust without complaint.
Recipe 1: Adaptive Antidot (recommended)
This is the combination to run if you want a clean clear with the broadly useful reward.
| Slot | Item |
|---|---|
| Tissue Flask | Mutated Flesh Sample |
| Catalyst Flask | Biogel |
| Reagent Flask | Crystal Dust (from Psy-Crystal) |
| Data-Crypt Connector | Data-Crypt H-41-OK |
Fill all four, confirm each slot reads green, then press the central console button to mix. You walk away with Adaptive Antidot x6. Each one grants immunity to toxic damage for the fight, at the cost of -10 Toughness until the end of combat. Toxic immunity wins more encounters in this stretch of the game than a small Toughness dip costs you, so this is the one we lead with.
A note on names: some wikis call the in-machine product of this combo "Shimmering Emulsion." The consumable you actually keep is Adaptive Antidot. Same recipe, different label on the intermediate step.
Recipe 2: Elixir of Warp Neutrality (alternate)
If you would rather have a Warp-damage answer in your back pocket, run this instead. Note the Tissue Flask wants the plain Flesh Sample, not the Mutated one, and the Data-Crypt code flips.
| Slot | Item |
|---|---|
| Tissue Flask | Flesh Sample |
| Catalyst Flask | Unidentified Acid |
| Reagent Flask | Adamantine Dust (from Adamantine) |
| Data-Crypt Connector | Data-Crypt K-04-OH |
For this one you transduce the Adamantine into Adamantine Dust. The reward is Elixir of Warp Neutrality x6: immunity to Warp damage for the fight, with -10 Fellowship until the end of combat, and the user cannot deal Warp damage during that window. It earns its slot against Warp-heavy enemies, but it stays situational, which is why Recipe 1 is the default.
Watch the codes. Recipe 1 uses H-41-OK, Recipe 2 uses K-04-OH. They look alike and swapping them breaks the mix.
One attempt, one reward
The two recipes share materials and the console only produces one batch, so you receive one of the two rewards, not both. Pick the recipe you want before you start loading slots.
More important: an incorrect combination causes the lab equipment to explode, leaving the machine useless and costing you the reward entirely. Treat this as a single real attempt. Match one of the recipes above to the letter and you are fine.
Where the materials are
You gather everything inside the station while working through the quest. The Mutated Flesh Sample comes off a corpse near the statue in the northwest corner of the central chamber. Data-Crypt H-41-OK sits on a desk you reach after the guard cutscene. The room directly north of the central chamber holds the rest: Biogel is in a yellow loot crate, and the Psy-Crystal is in a large red crate in that same room. The station also scatters Adamantine, Flesh Sample, Unidentified Acid, and Data-Crypt K-04-OH through its rooms and lab boxes for the alternate recipe.
You will also find Black Water in the loot here. Neither working recipe uses it, so leave it alone and do not waste a slot on it.
After the lab
Clearing the console keeps the "Secrets of the Navis Nobilite" quest moving toward bringing Cassia aboard as your Navigator. Once she is in the seat, our Cassia build guide covers how to spec her for the rest of the campaign.
