The base in Arknights, officially known as the RIIC facility, is far more than a background feature; it is the silent engine that keeps the operations running. This allows for development related to LMD, Battle Records, materials, and drones, which are key to the growth of your operators and progress in the story.
Building a solid base is key to success, entailing less grind for more steady growth. In this guide, find the best layouts, learn how to create resource loops, and learn how to manage operators for maximum efficiency without complicating your daily routine. Arknights top up from LootBar will make your base building journey smoother, so make sure to get some Originium before starting with your base building.

Understanding the Core Facilities
Each of the facilities serves a different purpose, and one's productivity is determined by how one balances them.
Factory
This is the backbone of resource generation. It issues out Pure Gold, Battle Records, and also goes after Originium Shards and Dualchips. Up to three operators may be put into a Factory, which in return presents different bonuses according to what the operator's base skills are. Factories run on auto mode but will stop at full capacity, which in turn will cause production to halt, so get to it and collect often. Since everything from LMD to EXP depends on factory output, upgrading these early pays off.
Trading Posts
Trading Posts turn Pure Gold into LMD, the lifeblood of Arknights' economy. A well-staffed Trading Post keeps the cash flowing into promotions and upgrades. At Level 3, they are also able to convert Originium Shards into Orundum, though this is less efficient if you still need LMD. Keeping two Trading Posts means your Pure Gold is never idle.
Power Plants
These will power your energy supplies, but also create drones which speed up either production or upgrades - if the generation of power becomes inefficient, your other rooms cease to function. It is very important to keep enough running to support your layout, especially with upgrading other facilities that use increased power.
Dorms
The resting quarters for operators. Morale influences base performance directly, as a tired team will lower productivity. Upgrading the Dorms allows more operators to rest, therefore keeping morale and work continuous.
Other facilities include the Reception Room, HR Office, Training Room, and Workshop. These all serve specific purposes: Reception Room collects clues for the Friend Credit Store, HR Office speeds up refreshes of recruitment, Training Room allows Mastery training, and Workshop crafts materials.
Best Base Layouts and Their Purpose
Players often refer to layout codes such as "2-5-2" or "2-4-3." These refer to the number of Trading Posts, Factories, and Power Plants you have in your base. The numbers define how your base balances output and power.
The 2-5-2 is the best layout for long-term efficiency: for the purpose of maximising Pure Gold and Battle Record output, one has 2 Trading Posts, 5 Factories, and 2 Power Plants. However, this leaves little in the way of spare power, so one has to manage morale with care and rotate frequently. It is often preferred for non-stop output by players who top up Arknights and maintain the strong operator rosters.
This additional 2-4-3 arrangement is better and easier to use. We replace one Factory with an extra Power Plant, which will, in turn, give additional amounts to balance out energy-hungry rooms like the Dorms or Reception Room. You will have a little less resource output, but will get some stability and ease of management in return. For mid-game players, this layout is very convenient as it doesn’t sacrifice much in production.
Some late-game players will attempt 1-5-3, where, after amassing a large stockpile of LMDs, they take down a Trading Post. It is a niche setup that sacrifices flexibility for an increase in output. Generally speaking, most players do great with 2-4-3 for balanced or 2-5-2 for raw efficiency.
Creating Efficient Resource Loops
A good base is a loop wherein every facility feeds into another. The primary cycle is the manufacturing of Pure Gold in Factories, sending it to Trading Posts for LMD conversion, and that LMD is used for upgrades. Once your LMD flow stabilises, dedicate a few Factories to Battle Records for EXP or materials.
Drones
These are key for keeping the loop fast. They are generated over time in Power Plants, using which any Factory or Trading Post process can be instantaneously accelerated. Apply drones at the crucial moments, like just before a logout or when the queue is almost completed, to fit in that extra production cycle. Save some for construction or upgrades during events and reconfigurations.
Operators
Making good operator assignments is important because many operators provide base skills that greatly increase productivity. For instance, advancing Factories and Trading, or boosting drone regeneration, are skills that offer base stat increases. Assign the best personnel: Myrtle or Siege for Factories; Exusiai or Texas for Trading; Ptilopsis or Silence for Power Plants. And remember to take care of tired operators in the Dorms.
Facility Priority
Improve facilities in order of priority. Factories and Trading Posts come first because they power the economy, then Power Plants to keep up the load. After some level of stability in production is reached, upgrade the Dorms and auxiliary rooms, such as the Reception or the HR Office. Balanced upgrades prevent unwanted downtime and power shortages.
Tips for Maximising Base Efficiency
While layout and operator assignment do the bulk of the work, a few practices will see your base run much more smoothly. Always get what you can from factories and trading posts before they hit full capacity. Once storage is at max, your production grinds to a halt, which in the long run reduces your efficiency if you aren’t aware of it.
Also, rotate operators out to the advancement each day to maintain morale. Don't burn out your top Factory or Trading Post operators. Have some secondary operators with average base skills ready that you can pass tasks off to when you don't want to break production.
Once you get into your groove, avoid excessive changes of layout. Constant rebuilding of the facility setup burns resources and time. Commit to one efficient setup and fine-tune within the structure, rather than tearing it down.
Conclusion
The base in Arknights is the unsung hero of your roster's strength. Master how each room works, connect your resource loops, and know how morale will drive productivity to raise progress across the board. For the most part, the 2-5-2 layout remains the gold standard for maximum output, but 2-4-3 offers easier, low-maintenance balance.
With effective drone management, operator rotation, and resource collection, your base will work like a well-oiled machine. Approach it with the same zeal as a combat strategy, and it'll reward you with an endless supply of LMD, materials, and a thriving Rhodes Island economy.
