TL;DR

Lunafilament (also called Lim) is Pragmata’s main currency, used exclusively at the Unit Printer in the Shelter.
It comes from defeated enemies, Safe Boxes, yellow supply boxes, Red Zones, and Training Simulations.
Enemies respawn when you use an Escape Hatch and return. This makes any dense combat room a viable farm loop.
Training Simulations are the most efficient Lunafilament source per minute once you unlock them — especially early courses.
The Pocket Refinery Mod gives a permanent 10% bonus to all Lunafilament gains. Get it from the Business District Red Zone in Mass Production Array as soon as possible.
Pure Lunum is not farmable like Lunafilament — it is fixed and finite. Do not confuse the two.
Do not hoard Lunafilament. There is almost no reason to save it — spend it every time you return to the Shelter.

What Is Lunafilament and What Does It Do?

Lunafilament — shortened to Lim by players and sometimes the game itself — is the primary currency in Pragmata. It looks like small blue crystalline fragments. You will see it constantly while exploring: scattered on floors, dropped by enemies, sitting inside boxes, and rewarded by nearly every activity in the game.

Lunafilament funds everything at the Unit Printer in the Shelter. That means:

Printing permanent copies of weapons you find in sectors (100 Lim per initial print)
Upgrading weapons to improve damage, ammo capacity, and fire rate
Printing hacking nodes for Diana’s grid
Upgrading those nodes to increase their power
Unlocking abilities like Thruster Charges and Auto-Hacking
Upgrading attachments like Mod Slots, Node Slots, and Repair Up

It does not fund the Firmware Updater — that terminal uses Upgrade Components, which are a separate and much more limited resource. And it does not buy things at the Cabin Stamp Club — that uses Cabin Coins. Lunafilament is purely a Unit Printer currency.

Because it funds so many interconnected systems, players who under-farm Lunafilament consistently fall behind on weapon upgrades, hacking node quality, and attachment unlocks. Staying ahead of the curve means treating farming as a regular habit rather than something you only do when you feel stuck.

One critical note upfront: Lunafilament is farmable. Pure Lunum is not. Pure Lunum is found at fixed locations across sectors and cannot be respawned or infinitely ground. If you are running low on Pure Lunum specifically, see our Pragmata red keys and red zones guide — Red Zones are the most reliable consistent source. This guide focuses entirely on Lunafilament.

Every Source of Lunafilament in Pragmata

Defeated Enemies

Every enemy you kill drops Lunafilament. Standard walker bots drop smaller amounts; tougher elite bots and the larger humanoid enemies drop significantly more. The exact amount scales with enemy difficulty, so the harder the fight, the better the payout.

The key mechanic that makes enemy farming viable: enemies respawn every time you use an Escape Hatch and return to the Shelter. This is Pragmata’s version of the Dark Souls bonfire — resting resets the world’s enemies. The game is explicit about this. When you use a Hatch, it shows you a list of what you have collected, which includes a note that enemies will be back when you return.

This means any area with a dense enemy encounter becomes a repeatable farm loop. Find a Hatch, clear the room, use the Hatch, come back, clear again. You do not lose any resources when you die, so the risk of farming stays low as long as you use Escape Hatches regularly to lock in your gains.

Best enemy farm rooms are combat encounters with multiple enemies in a tight space, where kill density per minute is highest. The Mass Production Array and Lunum Mines both have several dense rooms that are efficient for quick runs.

Safe Boxes

Safe Boxes are the white and orange crates scattered throughout every sector. They are one of the most valuable resource containers in the game because each one contains either a Cabin Coin, at least one Upgrade Component, or varying amounts of Lunafilament.

Some Safe Boxes contain significant Lunafilament payouts — particularly the ones that are harder to reach, behind Holo-Walls, or locked behind story abilities like the Lim Eraser or Cleansing. A first-time thorough sweep of a sector picking up every Safe Box provides a meaningful Lunafilament injection on top of whatever you earned from combat.

Safe Boxes do not respawn after using an Escape Hatch. They are one-time pickups per playthrough. This means there is a ceiling to Safe Box farming, but it also means leaving Safe Boxes behind is leaving permanent currency on the table. Open every one you find. For the location of every Safe Box in each sector, see our individual sector guides:

Yellow Supply Boxes

Yellow supply boxes are smaller and more common than Safe Boxes. They sometimes contain Lunafilament, Data Shards that fill Diana’s Hacking Gauge, and Repair Kits. They are worth opening as you pass through areas, though their individual payouts are smaller than Safe Boxes or enemy drops.

Do not go out of your way to hunt for these specifically — just open them when you see them. Over the course of a full sector run they add up to a meaningful bonus on top of your other income sources.

Red Zones

Red Zones are the locked combat arenas that require a Red Gate Key to enter. Clearing one rewards a guaranteed Pure Lunum and often a Mod or Storage Expander alongside it. They also drop Lunafilament from the enemies inside, though this is a secondary benefit compared to the Pure Lunum payouts.

Red Zones are not primarily Lunafilament farms — they are too key-gated for repeatable grinding — but clearing every one you find naturally keeps your Lunafilament reserves healthier while also delivering the more important Pure Lunum rewards. Think of Red Zone Lunafilament as a bonus on top of the reason you are running them.

Training Simulations

This is the most underrated and most efficient Lunafilament source in the game once it becomes available.

Training Simulations unlock at Shelter Level 2 via the Sim Pod located next to Cabin in the Shelter. Each sim is a self-contained combat challenge using a preset loadout — your actual gear and upgrade levels do not affect the difficulty, which means you cannot be under-levelled for a sim. Performance is based purely on execution.

Every completed Training Sim course rewards a Cabin Coin just for finishing it. Hitting the optional objectives within each sim rewards additional materials — Lunafilament, Upgrade Components, Pure Lunum, and more, depending on the course. The early Training Sims are relatively straightforward and deliver solid Lunafilament rewards for the time investment.

You unlock new Training Sim courses by finding Training Data scattered through sectors. The more Training Data you collect, the more courses become available, and the more repeatable farming content you have access to. For every Training Data location, see our Pragmata training data locations guide.

Early sims are efficient enough that grinding a few extra runs specifically for Lunafilament income is genuinely worthwhile, especially when saving toward a more expensive upgrade tier. Later sims get harder — around course 15 to 20, difficulty spikes noticeably — but the early ones remain accessible throughout the whole game.

Exploration and Floor Pickups

Lunafilament also appears as loose pickups sitting directly in the environment — on floors, ledges, in corners, and sometimes in hard-to-reach spots that require platforming or scanning to spot. These are not worth going drastically out of your way for individually, but collectively across a full sector sweep they contribute meaningfully to your total.

Diana’s Item Scan ability from the Unit Printer highlights nearby collectibles and resource pickups, including loose Lunafilament deposits in the environment. Unlock this early and use it constantly while exploring — it removes the guesswork from whether a side path or elevated platform has anything worth climbing to.

The Pocket Refinery Mod — Your Most Valuable Passive Income Boost

The Pocket Refinery Mod is a passive mod that permanently increases all Lunafilament gains by 10%. Every enemy kill, every box, every floor pickup — all of it yields 10% more for as long as the mod is equipped.

10% sounds modest, but across an entire playthrough with thousands of individual Lunafilament pickups, it compounds into a substantial total. More practically: it means every enemy farm loop and Training Sim run consistently pays out more than they would without it.

Where to get it: Complete the Red Zone in the Business District in Mass Production Array (Sector 2). This Red Zone involves multiple wave enemies including two Executor robots, making it one of the harder Red Zones in Sector 2. But it is absolutely worth pushing through. Equip Pocket Refinery immediately and keep it in your Mod rotation throughout the rest of the game.

This is one of the few Mods worth prioritising as a permanent slot fixture rather than swapping in and out situationally. The passive income advantage it provides across the whole campaign is real. For the full breakdown of which Mods are worth equipping alongside it, see our Pragmata best mods guide.

The Best Lunafilament Farming Loop

Once you have the Pocket Refinery Mod equipped, the most efficient regular farming pattern is:

Step 1 — Find a dense combat room with an Escape Hatch nearby. The Mass Production Array and Lunum Mines both have several rooms that fit this description well. Look for rooms where three or more enemies spawn in a tight space, close to an active Hatch.

Step 2 — Clear the room. Kill every enemy. Pick up all drops.

Step 3 — Use the Escape Hatch. This takes you to the Shelter, lets you spend your Lunafilament at the Unit Printer, top up your Repair Canisters, and adjust your loadout.

Step 4 — Return via tram to the same Escape Hatch. Enemies have respawned. Clear again.

Step 5 — Run Training Sims between loops. While at the Shelter after each farm loop, run a Training Sim or two for the guaranteed Lunafilament and Cabin Coin rewards. This makes your Shelter visits productive even if you do not need to upgrade anything immediately.

This loop works throughout the full campaign. It is not glamorous, but it is reliable, low-risk, and improves in efficiency every time you upgrade your weapons and hacking to clear rooms faster.

How to Spend Lunafilament Wisely

Farming efficiently only matters if you are spending well. A few principles that help:

Do not hoard it. Lunafilament has no investment value sitting in your wallet. Spend it every time you visit the Shelter. There is almost no scenario where saving Lunafilament for later pays off better than spending it now on an upgrade that makes your current sector easier.

Print new weapon blueprints immediately. Every new weapon blueprint you find costs 100 Lim to print and unlock for your loadout. This is one of the cheapest purchases in the game and unlocks combat options that could make a meaningful difference. Always print new finds before upgrading existing weapons.

Prioritise Mod Slots and Node Slots early. More slots mean all your other Unit Printer investments become active simultaneously. These are among the highest-leverage purchases at the Unit Printer. For the full spend priority breakdown, see our Pragmata Unit Printer guide.

Do not spend on weapons you do not use. Upgrading a weapon that does not fit your playstyle wastes Lunafilament that could have gone toward a Decode upgrade or a Mod Slot. Only invest in weapons you actively run in your loadout. For the full weapon list and which ones are worth investing in, see our Pragmata all weapons guide.

Late-game upgrades need both Lunafilament and Pure Lunum. Once you hit the higher upgrade tiers, the Unit Printer requires both currencies simultaneously. This means running out of Pure Lunum bottlenecks you even if your Lunafilament reserves are full. Keep Pure Lunum coming in by clearing every Red Zone. Check our Pragmata red keys and red zones guide to make sure you are not missing any.

Lunafilament vs Pure Lunum — Key Differences

Players new to the game often conflate the two upgrade currencies. Here is the short version:

	Lunafilament	Pure Lunum
Also called	Lim	—
Appearance	Small blue fragments	White Delphi crates
Used at	Unit Printer	Unit Printer (high-level upgrades)
Farmable?	Yes — infinitely via enemies and Training Sims	No — fixed locations only
Main sources	Enemies, Safe Boxes, Training Sims, floor pickups	Red Zones, Delphi crates, Training Sim rewards
Best passive boost	Pocket Refinery Mod (+10%)	Object Scan ability (easier to find all of them)

The biggest mistake is spending Pure Lunum too liberally early on because you mistake it for another type of farmable currency. Lunafilament you can always earn more of. Pure Lunum you cannot. For the Firmware Updater specifically, which uses neither — see our Pragmata best firmware upgrades guide for that separate system.
