Blind Descent Crafting Guide: Modular Tools and Upgrades

Crafting in Blind Descent relies on a mix of on-the-go modular assembly, dedicated workbenches, and specialized outpost tech stations scattered beneath Mars. Developed by Pokuch, this subterranean survival adventure equips you with an AI companion named Holowatch while forcing you to harvest Martian flora, insect carapaces, and crashed expedition scraps to stay alive. Navigating the depths of the Hyperion Excavation site requires understanding how handles, heads, and binders interact, as well as how to repair vital medical and water purification systems before infections take over.

How Handcrafting and Modular Tool Assembly Works

Blind Descent features a freeform modular crafting mechanic for basic hand tools and weapons. By pressing the handcrafting key (default C), you can combine three distinct material slots—a handle, a head, and an optional binder—to determine the behavior, damage profile, and durability of your equipment.

Every improvised tool begins with a handle. The length and sturdiness of the handle dictate whether an item functions as a fast swinging weapon, a heavy implement, or a polearm:

• Short handles or short sticks produce one-handed tools like hammers.
• Long branches produce two-handed mallets or spears.
• Salvaged items like spotlight handles can also be repurposed as sturdy handles.

The head attached to the handle decides the damage type and core function. Fastening a basic stone gives your tool blunt bludgeoning properties, while attaching sharp mountain mite legs or crab claws yields piercing spears and slashing daggers. If you attach an organic acid sack, the weapon deals corrosive acid damage, which melts the pink alien growths blocking doors and corridors.

The binder acts as the stabilizing agent. Wrapping materials such as vines around the joint reinforces the construction and increases total tool durability.

Essential Early Game Tools and Survival Recipes

Before you can build formal furniture or delve into the dark tunnels of Mars, you must establish immediate shelter and solve water contamination. Standing water in the caverns should not be trusted unless boiled or processed, and unshielded camps are rapidly reclaimed by aggressive creeping root clusters.

To survive your initial cycles, craft these basic items in the field:

1. Stone Axe: Gather sticks, stones, and vines from the ground. Use it to chop down banana trees, harvest kindling, and cut heavy branches.
2. Campfire / Fire Pit: Open the building menu (B) to clear ground foliage and place a fire pit using stones and sticks. Fire allows you to boil water, roast harvested meat, maintain optimal body temperature, and repel nocturnal pests.
3. Coconut Canteen and Bowls: Chop palm trees to obtain coconuts and banana leaves. Combine them into a coconut canteen or use a coconut bowl to boil standing water over a lit fire until safe to drink.
4. Leaf Mattress and Shelter: Collect eight leaves and a vine to craft a leaf mattress, then install it onto a bed frame (holding R to inspect and F to install). Sleeping for six to eight hours skips hazardous night phases and resets active stamina penalties.

Ranged Combat: Crafting Bows and Harvesting Arrows

Melee combat against infected wildlife can rapidly deplete your health and expose you to toxic gas. Crafting a ranged setup gives you the ability to pick off spitters and silk worms from safety.

Making the Makeshift Bow

The makeshift bow requires flexible organic parts and salvaged human wiring. You can assemble it by gathering:

• One mountain mite leg (obtained by defeating mites near the waterfall routes)
• One utility line spool (found inside crashed containers and abandoned expedition sites)
• One resilient vine

Sourcing Arrows from Exploding Plants

You do not carve traditional arrows at a workbench. In the Martian subterranean biome, straight cactus-like exploding plants serve as natural arrow quivers. When struck with a thrown rock or a melee weapon, these flora pods burst open, dropping dozens of harvestable reeds that immediately function as standard arrows.

Arrows shot into enemies can frequently be retrieved from their corpses after combat. Furthermore, you can attach local flora materials—such as acid payloads from harvested gland sacks or explosive organic pods—directly to your equipped arrow to fire specialized chemical shots into dense creature clusters.

Workbench and Base Upgrade Station Recipes

Advancing beyond primitive stone tools requires dedicated workstations. You will utilize two primary crafting hubs: the deployable wooden Workbench and the fixed Outpost Upgrade Station.

Building the Workbench

The workbench unlocks mid-tier defensive gear and formal base storage. You can place it from the construction menu (B) once you have prepared:

• Multiple wood sticks
• Split logs (created by placing a felled tree log on the ground, holding an axe, and pressing F to split it lengthwise)

The workbench enables the following critical recipes:

• Wooden Chest Plate and Wooden Leg Plates: Crafted from heavy branches and vines. Equipping a full wooden set replaces burned cave suit remnants, granting 100 armor durability against aggressive creatures.
• Wooden Shield: Crafted from branches, providing a frontal block that negates incoming ranged spit attacks and melee rushes.
• Storage Chest: Provides permanent item storage to prevent your inventory from overflowing with bulky tree trunks and kindling.
• Water Skin: An upgrade over makeshift shells, requiring gathered leather and vines.

Restoring the Outpost Upgrade Station

Inside the abandoned expedition outpost, you will encounter a broken Upgrade Station. To bring it online, search the Waterfall Cave area for a functional processor board dropped by previous survey personnel, insert it into the console, and hook up the base power line.

The restored Upgrade Station unlocks advanced modifications:

• Cave Suit Backpack Upgrade: Expands your on-character inventory grid from three rows to four rows, significantly reducing the frequency of encumbrance during exploration runs.
• Monster Armor: Combines soldier silkworm chunks, silkworm slime, and suit patch kits to produce high-durability armor with superior damage resistance over wooden plating.
• Tech Light Modifications: Allows you to attach glowing Lunar Light Plants directly onto your suit armor or waist slots (using X), functioning as a hands-free lantern that leaves your off-hand free for shields.

Outpost Station Repairs and Medical Crafting

Survival beneath Mars is complicated by an ongoing biological infection that steadily builds up in your system. Surviving requires keeping the abandoned base's mechanical hubs fully powered and repaired using local resources.

Water Purifier and Nutrient Processor Repair

The outpost water purifier cannot operate until you manually fix its broken conduits:

1. Replace the broken fluid pipe by slotting in a hollow bamboo stick.
2. Puncture a harvested yellow watermelon using a hollow stick, then mount the pierced fruit onto the top input spout.
3. Replace worn power cabling with a fresh vine to maintain at least 200 durability.
4. Slide an empty bowl or canteen underneath the bottom output to catch clean, automated drinking water.

Medical Station Diagnostics and Injections

Whenever your infection resistance drops or contamination alerts sound, enter the medical module, run diagnostics on the terminal, and prepare suppressors:

• Infection Suppressor: Crafted at the medical fabricator using infected hearts (harvested from spore zones like B4) and ember leaves. Injecting a dose (E) halts pathogen progression and keeps contamination within safe tolerance levels.
• Vitality Injectors and Gut Flora Stabilizers: Crafted using snout pods collected from hanging alien plants. These injectors restore raw vitality and neutralize gastrointestinal poisons contracted from consuming unvetted flora.

Frequently Asked Questions

How do I open the crafting menu in Blind Descent?

Press C on your keyboard to open the modular handcrafting screen, which lets you combine handles, heads, and binders. To access structural recipes like campfires, workbenches, and beds, press B to open the construction menu.

How do I split logs to make a workbench?

Fell a tree with your stone axe to create a log. Drop the log onto the ground, equip your axe, target the log, and hold the interaction key (F) to split it lengthwise into split logs.

Can I drink unboiled cave water safely?

No. Standing cave water is contaminated and unsafe to drink unless it has been boiled in a container over a campfire, run through the outpost water purifier, or rendered harmless by unlocking the symbiotic Xeno-digestion mutation.

What happens when tools break in the field?

Tools have active durability bars that degrade with each strike against wood, stone, or enemies. Adding high-quality binders like vines during assembly raises base durability, but once a tool breaks, you must handcraft a replacement using gathered resources.
