Preparing for the next stage of ARC Raiders is not only about collecting better weapons or chasing ARC Raiders BluePrints. Your material stash can have just as much influence on how quickly you move through new crafting requirements, especially when advanced equipment asks for several uncommon components at once.

If you have been collecting ARC Raiders BluePrints during your regular runs, now is a good time to check whether your materials actually support them. A blueprint can sit unused for a long time when the required parts are missing, while a little preparation can let you craft new equipment much sooner.

Start With Materials That Are Hard to Replace

The easiest rule is to protect anything that comes from rare ARC enemies. These components are generally more valuable for progression than their trade value suggests.

ARC Circuitry and Motion Cores should stay in the stash when possible. They are important for Level 3 workbenches and Medium Shield crafting, so selling them can create unnecessary problems when you reach the next upgrade.

Leaper Pulse Units and Bombardier Cells are also worth keeping. Their drop rates and enemy encounters can make them frustrating to farm on demand. If you only have a small number, there is little reason to trade them away unless you are completely finished with the progression they support.

Give Boss Materials Their Own Priority

Boss Reactors are among the materials I would never casually sell. Matriarch and Queen Reactors are connected to high-end crafting and powerful weapons, including the Aphelion.

These items should be treated almost like permanent progression assets. Once one enters the stash, I would leave it there until a specific crafting requirement calls for it.

That mindset is useful before a major update because it prevents a common mistake: selling a rare item today and discovering tomorrow that the same material has become essential for a new project.

Refine Without Overproducing

High-tier components can also be worth preparing, but there is a difference between being ready and crafting too much.

Advanced Electrical Components and Advanced Mechanical Components are useful for Mk. 3 equipment and other late-stage projects. Keep a healthy supply, but do not feel that every raw ingredient needs to be converted immediately.

Heavy Gun Parts are a good example of something worth preparing in moderation. At Refiner Level 2, four Simple Gun Parts can be turned into a Heavy Gun Part. Making some before a major weapon upgrade can reduce downtime when you are ready to improve your loadout.

Batteries Are Easier to Underestimate

Batteries and Steel Springs can disappear quickly when working on later workshop projects. Some requirements can demand dozens of batteries, which makes them more important than their ordinary appearance suggests.

I would not fill the entire stash with them, but keeping a reasonable reserve is smart. If your inventory is already crowded, prioritize rare enemy components first and then decide how many refined or workshop materials you can comfortably store.

Household Items Still Have a Purpose

ARC Raiders has a habit of making ordinary household objects surprisingly useful. Toasters are needed for Gunsmith upgrades and can often be found in residential areas.

Motors are another item worth grabbing from vehicle wrecks. Fried Motherboards and Damaged Heatsinks also deserve some attention because they can contribute to Utility Station progression.

These are the kinds of items I used to think of as disposable junk. Once you understand their upgrade value, however, it becomes much easier to recognize why experienced players leave them in the stash instead of selling them immediately.

Seeds Are More Useful Than They Look

Assorted Seeds are another unusual resource that should not be ignored. They can be used with Celeste as an alternative form of currency for obtaining specialized resources.

That makes them useful when your stash is missing a particular material. Rather than spending time searching for every individual component, having seeds available can give you another route toward what you need.

The Three-Stack Rule Keeps Things Manageable

Common materials should have a much lower storage priority. Metal, Rubber, Plastic, Fabric, and Chemicals are useful, but there is little benefit in allowing them to occupy every available slot.

I usually recommend keeping around two or three stacks of each common raw material. Anything beyond that can be refined, used for upgrades, or sold depending on current needs.

This rule also makes the stash easier to understand. When you return from a raid with rare ARC parts, you know there is space available instead of having to throw away something useful because five stacks of Plastic are taking up the inventory.

Clean Up Before You Start the Next Phase

The final preparation step is simple but easy to forget. Use Merge Stacks whenever partial stacks begin spreading across the stash. It can immediately recover several slots without requiring you to discard anything.

It is also better to keep raw materials than huge amounts of finished low-tier consumables. Ammo, basic augments, and Tier 1 Shields can be crafted when needed, while their ingredients generally give you more flexibility.

Final Thoughts on Part 2 Preparation

A well-managed stash should support your ARC Raiders BluePrints rather than simply collect everything you encounter. If you are missing something specific, ARC Raiders Materials for sale can be an option for players who want to reduce repetitive farming and spend more time on raids and progression.

The best approach is still selective hoarding. Protect rare ARC drops and boss materials, maintain useful reserves of advanced components, keep important household junk, and limit basic resources to a few stacks. That gives you enough preparation for Part 2 without turning your stash into an unmanageable warehouse.
