Endfield AIC guide — optimize your factory fast

By Liam STIM, 48

introduction

Arknights: Endfield brings a new layer to the gacha formula. beyond characters and combat it adds a factory system called AIC. this system is not a side feature. it shapes progression, resource flow, and long term play. players who master AIC reduce grind and gain steady advantage. they also free time for events and banner pulls. i write guides because i like clear steps and practical setups. this piece walks you from first blueprints to late game scaling. it is for players who want to build efficient loops and avoid wasted resources. if you want a broader strategy that ties AIC to economy and live ops see the guide complet pour gamer for full context.

what is the AIC factory and why it matters

core concept

AIC is a modular factory. you place modules that extract, refine, and assemble resources. each module has inputs and outputs. some modules run continuously. others need maintenance or rare materials. the factory links to your base and to expedition systems. it can produce upgrade mats, crafting parts, and event tokens. mastering AIC shortens the path to gear and reduces reliance on gacha drops.

why it changes progression

most gacha games focus on combat loops. Endfield adds a production loop. this loop rewards planning. a well tuned factory gives predictable yields. that predictability matters for planning banner pulls and for completing timed events. it also creates new play styles. some players will focus on factory optimization. others will trade factory output for combat time. both paths are valid. the key is to know the trade offs.

early game goals

in the first week aim for three things. unlock basic extractors. set up a steady fuel source. and build one refining chain that converts raw ore into upgrade mats. these steps give you a buffer. with a buffer you can skip low value grinding. you can also test module placements without risking progress.

early setups: blueprints, resource loops, and bottlenecks

first blueprints to prioritize

start with these modules. ore extractor. basic refinery. storage unit. fuel generator. the extractor gives raw material. the refinery converts it. storage smooths output spikes. the generator keeps modules running. place them close to reduce transport time. transport time matters. long transport reduces throughput.

resource loops explained

a resource loop is a chain of modules that feed each other. a simple loop looks like this. extractor produces ore. refinery turns ore into ingots. assembler uses ingots to make parts. parts feed a crafting bench that produces upgrade mats. repeat. the goal is to balance input and output so no module sits idle for long.

AIC resource flow
[extractor] -> [refinery] -> [assembler] -> [craft bench] -> output

common bottlenecks and fixes

power shortages. upgrade your generator or add a secondary fuel line. transport delays. shorten distances or add conveyors. storage overflow. increase storage or throttle production. module mismatch. adjust module levels so outputs match inputs. small fixes early prevent large slowdowns later.

mid and late game automation: scaling and meta

scaling principles

scale by replication not by single module power. duplicate efficient chains. two balanced chains beat one oversized chain. use parallel lines to increase throughput. monitor resource sinks. events often require specific mats. keep a dedicated line for event items when possible.

meta considerations

some modules have synergies. for example a catalyst module increases refinery yield when paired with a heat exchanger. these synergies change the optimal layout. track patch notes. meta shifts when new modules arrive. adapt quickly. players who test new combos early gain advantage in limited time events.

example midgame blueprint

module	level	role	notes
ore extractor	3	input	place near resource node
refinery	4	convert	pair with heat exchanger
assembler	3	combine	parallel two lines
storage	2	buffer	avoid overflow
generator	3	power	add backup fuel

practical blueprints and step by step builds

starter blueprint

place one extractor, one refinery, one assembler, one storage, and one generator in a compact layout. connect them with short conveyors. set refinery to low throughput to avoid storage overflow. run this for 24 hours. check output. adjust refinery speed if storage fills too fast.

intermediate blueprint

duplicate the starter chain. upgrade refinery to level 3. add a catalyst module to one chain to test synergy. keep the other chain as baseline. compare yields after 48 hours. the catalyst chain should show higher yield per input. if not, check power and transport.

late game blueprint

build three parallel chains. dedicate one chain to event mats. use advanced storage with priority routing. add automated maintenance drones to reduce downtime. at this stage you focus on uptime and event readiness. small downtimes cost more as demands rise.

tips for efficiency and long term planning

daily routines

check factory once per day. clear bottlenecks. claim storage. rotate event line when needed. small daily actions prevent large backlogs.

resource allocation strategy

prioritize upgrade mats for core operators first. use factory output to fill gaps not to replace core farming. keep a reserve of fuel and rare catalysts. these reserves let you react to sudden event demands.

team and community play

share blueprints in your guild or discord. test variations and report yields. community testing speeds up meta discovery. keep a simple log. note module levels, layout, and average output per hour.

conclusion

mastering AIC is a long term investment. start simple. build balanced chains. duplicate what works. keep reserves for events. track patch notes and adapt. the factory rewards planning more than raw time. if you want a broader strategy that links factory output to banners and live ops see the guide complet pour gamer for deeper analysis. for help with gacha math and pull planning visit Endfield gacha cost — calculate your pulls and pity.
