The only three resources you need for your first dozen hours of research are Bioluminescent Shards, Crystalline Cortexes, and Scrap Servomotors. Mastering the farming loops for this core analysis material in Deep Crafter is the single most important factor in your early-game progression, gating everything from better tools to essential survival gear. Forget wandering aimlessly; focus on these three and you'll unlock the entire tech tree before you know it.
What Is Analysis and Why Does It Matter?
In Deep Crafter, progression isn't about levels—it's about knowledge. The Analysis Engine in your habitat is the gateway to every significant upgrade. By feeding it specific materials, you reverse-engineer alien biology, geology, and technology to unlock new crafting blueprints. The system is divided into three distinct research trees:
- Biological Analysis: Consumes Bioluminescent Shards. This tree unlocks bio-composites, improved medkits, and gear that interacts with alien flora and fauna.
- Geological Analysis: Consumes Crystalline Cortexes. This is your path to stronger alloys, advanced mining tools, and habitat reinforcements that can withstand the crushing deep-cavern pressure.
- Technological Analysis: Consumes Scrap Servomotors. This tree is crucial for power systems, vehicle components, and automated tools, using the wreckage of a forgotten robotic civilization.
Effectively, your progression is completely stalled without a steady supply of these three materials. The faster you can establish reliable farming routes for them, the faster you can conquer the hostile environment.
The First Material: Farming Bioluminescent Shards
Your first major goal is to secure a steady income of Bioluminescent Shards. These are the key to early armor upgrades and the filters needed to explore toxic areas. They are a guaranteed drop from the passive, floating creatures known as Glimmerflies.
Where to Find Glimmerflies
Glimmerflies congregate exclusively in the Sunken Grotto, a biome typically found adjacent to your starting location, characterized by its giant, glowing mushrooms and deep blue flora. They travel in swarms of 4-6 individuals. While they are harmless, the Grotto is not. The primary threat here are Cave Lurkers, aggressive predators that unburrow when you get too close. Move slowly and listen for their distinct chittering sound.
The Best Tool and Strategy
While you can kill Glimmerflies with your basic Cutter, it's inefficient and often sends the rest of the swarm scattering. The optimal tool is the Net Caster, which you can craft after your very first Biological Analysis.
- Craft the Net Caster: It requires 1 Copper Ingot, 2 Fiber Mesh, and 1 Acid Gland. Get the gland from the stationary Spitters near the habitat entrance.
- Approach a Swarm: Find a Glimmerfly swarm and position yourself so the majority are in a cone in front of you.
- Fire the Net: The Net Caster captures up to three Glimmerflies in a single shot. They are instantly converted into 1 Bioluminescent Shard each upon capture.
- Reposition and Repeat: Reload and capture the rest of the swarm. Using this method, you can clear a swarm in seconds.
The key is efficiency and awareness. Don't get greedy and charge into a swarm without first checking for the tell-tale disturbed soil that signals a hidden Cave Lurker.

Expected Yield and Time Investment
A typical run through the Sunken Grotto should take no more than 10 minutes. In that time, you can reliably find 3-4 swarms. With the Net Caster, this translates to approximately 12-18 Bioluminescent Shards per run. The Glimmerflies respawn every 45 minutes, so you can easily cycle this farm while you gather other resources.
The Second Material: Mining Crystalline Cortexes
Once you have a handful of shards, your next priority is the Crystalline Cortex. These strange, geometric minerals are the bottleneck for crafting better tools and reinforcing your habitat, which is essential for expanding your base into deeper, more hazardous zones.
Locating Geodesic Veins
Crystalline Cortexes are not found in standard resource nodes. They must be mined from special formations called Geodesic Veins. These veins look like clusters of pulsating, purple crystals embedded in the cavern walls. They are most commonly found in the Crystal Maw biome, a dangerous area filled with sharp crystalline structures and environmental hazards.
The Crystal Maw is easily identified by its jagged purple terrain and the constant, low humming sound that emanates from the crystals. The veins themselves emit a soft light, making them visible from a distance in the darkness.
Required Gear: The Reinforced Pickaxe
Your starting pickaxe will shatter instantly against a Geodesic Vein. You must craft the Reinforced Pickaxe to harvest a Crystalline Cortex. This is likely the first major gear check you'll face.
- Blueprint Unlock: Requires 2 successful Geological Analyses.
- Crafting Cost: 1 Titanium Ingot, 2 Copper Ingots, 1 Bioluminescent Shard.
Don't even bother entering the Crystal Maw without this tool. Each Geodesic Vein requires 5 hits with the Reinforced Pickaxe to break and yields a single Crystalline Cortex.
A Safe and Efficient Mining Loop
The Crystal Maw is treacherous. A simple and repeatable loop is the best way to farm Cortexes without risking death.
- Enter from the West: The western entrance to the Crystal Maw typically has fewer environmental hazards like steam vents.
- Stick to the Upper Ledges: Most Geodesic Veins spawn on the upper third of the cavern walls. Staying high allows you to spot them easily and avoid the aggressive, ground-based Crystal Crawlers.
- Mine, Move, Repeat: Identify a vein, use your jetpack to reach it, mine the Cortex, and immediately move to the next. Do not linger. There are typically 4-5 veins accessible from the upper ledges.
- Exit and Reset: Once you've harvested the accessible veins, leave the biome. The nodes will respawn in about 60 minutes.
Following this path, you can secure 4-5 Crystalline Cortexes in a 15-minute run with minimal risk.
The Third Material: Scavenging Scrap Servomotors
The final core material, the Scrap Servomotor, is your key to advanced technology, power, and automation. These are salvaged from the husks of derelict security drones, but this is by far the most dangerous farming loop of the three.
The Dangers of the Warden's Graveyard
Scrap Servomotors are found by deconstructing the remains of ancient robots in the Warden's Graveyard. This biome is a maze of metallic corridors and debris fields, littered with the deactivated forms of robotic Wardens. The primary danger is that not all of them are truly deactivated. A significant percentage (around 20%) are merely dormant and will reactivate to defend the area if you make a mistake during salvage.
How to Safely Deconstruct Derelict Wardens
You'll need the Breaker Tool for this job, a high-torque device that can pry open the armored chassis of the drones. It's unlocked via Technological Analysis.
The process is a tense mini-game:
- Approach a Derelict Warden: Find a drone that is completely still and has no illuminated lights.
- Initiate Salvage: Equip the Breaker Tool and interact with the Warden's main torso panel. This begins the deconstruction sequence.
- Watch the Light: A small indicator light will appear on your tool's interface. It will flash green three times, followed by a brief, random pause, and then a final flash. You must apply torque only during the green flashes.
- Avoid the Red Flash: If you apply torque during the pause or if a red light flashes, the salvage fails. This has a high chance of reactivating the Warden and any others nearby. If you succeed on all four green prompts, the panel opens.
- Collect the Servomotor: Once the panel is open, you can safely retrieve the Scrap Servomotor.

What to Do If a Live Warden Activates
If you fail the mini-game and a Warden powers on, do not fight it early on. Your starting gear is no match for its pulse cannon and armored plating. Your only option is to run. Break line of sight by ducking through the metallic corridors and use your jetpack to ascend to a higher level. They are relentless but clumsy, and can't pursue you effectively through vertical terrain. Wait for it to return to its patrol route before attempting another salvage.
Putting It All Together: Your First 10 Analysis Unlocks
Focusing your farming on these three materials will rapidly accelerate your progress. A balanced approach is best—do a run for each material, then return to your base to perform analysis and craft new gear. Here is a recommended priority list for your first ten unlocks to maximize your survival and exploration capabilities.

Deep Crafter Analysis FAQ
Can you buy or trade for analysis materials? No, there are no vendors or trading systems in Deep Crafter. All analysis materials must be found and gathered from the environment. This is a core part of the game's survival and exploration loop.
What's the most efficient way to get all three materials in one trip? Start in the Warden's Graveyard (most dangerous first), then cut through the Crystal Maw which often connects to it, and finish in the Sunken Grotto. This route lets you gather Servomotors, then Cortexes, then Shards in a single, long loop that ends near your starting habitat. This is a high-risk, high-reward run recommended for experienced players.
Do analysis materials and creatures respawn? Yes, all resources respawn over time. Glimmerflies (Shards) respawn in their biome approximately every 45 minutes. Geodesic Veins (Cortexes) respawn after about 60 minutes. The derelict Wardens (Servomotors) are the slowest, taking around 90 minutes to reset their salvageable status.
Is there a fourth analysis material? Yes, but much later in the game. Once you reach the final biome, the Abyssal Core, you will discover a fourth material required for endgame technologies. However, the three materials covered here are all you need for the first 80% of the game.
The Blueprint for Success
Don't treat resource gathering as a chore; treat it as a puzzle. Each of these three materials requires a different approach, a specific tool, and a unique strategy to acquire safely and efficiently. By mastering these three loops—the Glimmerfly net-hunt, the Geodesic Vein mining route, and the tense Warden salvage—you aren't just collecting parts. You're building the foundation that will allow you to conquer the crushing depths of Deep Crafter.
