A full inventory isn't a loot problem—it's a decision problem in Arc Raiders. We've all extracted with great items and zero space, then spent 20 minutes staring at piles of ammo, duplicate guns, and maybe useful later parts. The fix isn't memorizing a giant keep-list; it's understanding why an item deserves a slot.

• Closing: The System That Keeps Working

Below is the system we use to keep 10–15 free slots almost all the time, whether you're early game looting everything, midgame upgrading benches, or endgame drowning in blue weapons and keys.

↖ 1) The Core Rule: Stash Space Is a Resource, Not a Warehouse

When stash pressure hits, we make every slot earn its rent. This means we judge items by four questions:

1. Can we craft or buy it on demand? If yes, it usually doesn't deserve long-term storage.
2. Is it a bottleneck material for repairs/upgrades/attachments? If yes, it's premium.
3. Does it stack efficiently? A stackable material often beats a single-use item that doesn't stack.
4. Does it convert into something we always need (via recycling)? If yes, it can be stored as a compressed resource.

↖ What this means in practice?

• If you can replace it quickly (cheap trader or easy craft), we don't store much of it.
• If it keeps our good guns healthy and upgraded, we protect it.
• If it doesn't stack and isn't urgently needed, it gets used, equipped, recycled, or sold.

↖ 2) The 60-Second Post-Raid Routine

We use the same routine every extraction. It prevents stash paralysis.

Step 1. Sell obvious fluff first

• If you find duplicate blueprints you don't need, then sell them.
• If you find low-impact trinkets/novelties and you're space-starved, then sell them immediately.

Step 2. Keep bottlenecks before toys

• If you find batteries, springs, processors (topside-limited items), then keep them first.
• If you find mod components, then keep them—attachments are power.

Step 3. Ammo is the first sacrifice

• If your stash is tight and you're holding partial stacks (like 40 bullets), then sell them.

This means you're trading one stash slot for something you can craft quickly later.

Step 4. Recycle extra guns into future repairs

• If you already have more than your target number of a weapon, then recycle extras.

This converts bulky items into the parts you'll spend constantly repairing and upgrading your real loadouts.

↖ A quick decision table

↖ 3) Category-by-Category Stash Rules

↖ 3.1 Augments: Don't Hoard, Craft on Demand

If you craft augments reliably, then storing lots of finished augments is pure bloat.

• We typically store components, not finished augments.
• If you find yourself keeping many augments just in case, then you're paying stash slots to avoid a 10-second craft later.

Target stock (practical baseline)

↖ 3.2 Shields: Buy/Craft, Don't Store

If a trader sells a shield cheaply (or you can craft it with easy mats), then stockpiling shields is usually inefficient.

• Light shields are often cheaper to replace than to store.
• Medium shields can be crafted when needed.

Rule we live by

If you're storing multiple shields for later, then convert that stash space into batteries + circuitry instead.

↖ 3.3 Weapons: Cap Your Collection

Weapons are the biggest stash hog because they don't stack and encourage collector behavior.

Our practical caps

• If you're PvE-focused, then 3–4 of each weapon is enough.
• If you're PvP-heavy and extracting enemy guns often, then raise caps selectively—but keep caps.

The real reason

Extra weapons are not security; they are future repair parts. Recycling duplicates keeps your main guns healthy without clogging your stash.

↖ 3.4 Ammunition: Treat It as Disposable Inventory

Ammo stacks look harmless until you realize they eat slots faster than almost anything.

• If you can craft ammo cheaply, then stash-storing lots of it is paying rent for something replaceable.
• If you're heading into a boss/large ARC run, then bring a controlled amount—but don't warehouse it.

What we keep

↖ 3.5 Weapon Mods / Attachments: Never Let Them Sit Loose

Attachments are a sneaky stash killer because they:

• don't stack,
• feel valuable,
• and quietly occupy multiple slots.

Space-saving trick that always works

If you have loose attachments, then mount them onto any compatible gun immediately—even a gun you're not currently using.

This means you convert two stash slots into zero by parking attachments on stored weapons.

↖ 3.6 Quick Use Items: Keep What You Actually Deploy

Quick use tabs become junk drawers. Our approach: keep enough for your playstyle, not your anxiety.

Practical keep rules (PvE-first, adjustable for PvP)

Combo note we use often

If you're running smoke, then pairing it with a reveal/mark tool changes fights because it removes uncertainty. This means one stack of each can outperform three stacks of random grenades you never throw.

↖ 3.7 Keys: Use Them Before They Use Your Stash

Keys don't stack, so they become guaranteed bloat.

• If you hit ~9–11 keys, then we start queueing raids where the goal is simply: bring keys, spend keys, free slots.
• This keeps key value flowing back into materials and consumables you can stack.

↖ 4) Crafting Materials: What Actually Deserves Long-Term Space

This is where most stashes win or lose. Our principle: stock bottlenecks, cap basics, avoid dead-end parts.

↖ 4.1 Always Valuable Materials (We rarely sell these)

These are the materials that keep your best gear operational.

Why the targets are ranges, not one magic number

If you're repairing two blue guns per night, then your advanced mechanical buffer evaporates. If you mainly loot and avoid fights, then you can run leaner. The target is a control knob, not a rule carved into stone.

↖ 4.2 Cap These Basics

Basic resources feel safe to stockpile… until they occupy half your stash.

If you see a third row forming, then you're not prepared—you're under-using crafting or over-looting low-value items.

↖ 4.3 Convert or Sell Materials (High emotion, low payoff)

Some items feel rare, but their practical value is low unless you're crafting a specific end product.

• If an item only matters for a legendary you don't actually run, then it's a luxury slot.
• If it breaks down into parts you always use, then treat it as convertible storage; otherwise sell.

↖ 5) A Clean Stash Blueprint

If you want an end state that stays stable, here's the structure we aim for.

↖ The layout we maintain

The hidden win

That flex space means you stop making bad decisions during extraction (I guess I'll drop the batteries?) and you stop panic-selling items you'll regret later.

↖ FAQ

↖ 1) If our stash is full after a raid, what's the fastest thing to sell first?

Sell duplicate blueprints, trinkets/novelties, and partial ammo stacks. If you still need space, recycle extra weapons beyond your cap.

↖ 2) Should we keep ammo at all?

If you can craft it easily, then ammo is mostly a just-in-time resource. We keep 0–2 stacks per relevant type, and only stock more for planned big ARC/boss runs.

↖ 3) Why recycle extra blue weapons instead of selling them?

Because recycling converts a bulky, non-stacking item into the exact repair/upgrading parts you repeatedly consume. Selling gives coins; recycling protects your long-term ability to keep top weapons healthy.

↖ 4) Attachments are clogging our stash. What's the simplest fix?

If you have loose attachments, then mount them onto stored weapons immediately. Even if it's not the perfect match, it's a stash-space win and you can swap later.

↖ 5) How many weapons should we keep?

If you're PvE-focused, then 3–4 per weapon is a strong cap. If you're PvP-heavy, then raise caps only for the guns you truly run—and recycle the rest.

↖ 6) Keys keep piling up—what's the rule?

If you reach ~9–11 keys, then schedule raids to spend keys until you drop back to a comfortable buffer. Keys are valuable only when converted into loot.

↖ Closing: The System That Keeps Working

A stash stays clean when every item has a job, a cap, and an exit plan. If you adopt the routine—sell fluff, protect bottlenecks, treat ammo as disposable, cap weapons, mount attachments, and burn keys on schedule—your stash stops being a second job.

The best part is the mental shift: if you find yourself hesitating over an item, then you already have the answer. Ask, Can we replace this faster than we can earn this slot back? If the answer is yes, it's not a keeper—it's a transaction.
