Why Upgrade Choices Matter
Upgrades can make an Alchemy Factory grow faster, but a poorly timed speed upgrade can also disrupt a production line that was already balanced. The most useful early choices reduce recurring costs or remove a genuine transport limit, leaving you free to build toward automation.
This guide focuses on the decisions that matter most when points are limited. Community experience consistently highlights fertilizer and fuel efficiency as strong early investments, while production and conveyor upgrades need to be coordinated so that machine demand does not exceed belt capacity.
The upgrade panel includes options for logistics, factory output, resource efficiency, sales, contracts, quests, and relics. That breadth makes it tempting to spread points everywhere. A narrower plan is usually easier to manage: solve the constraint currently slowing the factory, then move to the next one.

| Relic Knowledge | Relic Withdrawal Bonus |
Start With Cost Efficiency
Fertilizer Efficiency is a practical early priority because fertilizer costs can heavily affect wholesale profit margins. One advanced player guide recommends focusing upgrades on fertilizer while building simple bandage production, arguing that this creates a stronger mid-game through wholesale income.
Fuel Efficiency is similarly valued by players because production speed appears to increase heat consumption. If faster production makes a line consume fuel more quickly, fuel efficiency can help offset that added cost. This does not mean every point must go into fuel immediately; it means fuel should be considered whenever heat becomes the limiting expense.
Use efficiency upgrades when the factory is working but the cost of keeping it supplied is holding back expansion.
| Situation | Upgrade priority | Reason from player guidance |
|---|---|---|
| Fertilizer materially affects your income | Fertilizer Efficiency | Wholesale margins depend heavily on fertilizer costs |
| Production speed raises heat demand | Fuel Efficiency | It can compensate for increased fuel consumption |
| Early bandage wholesaling | Fertilizer Efficiency | Recommended as a focused early-game investment |
| You are not using basic fertilizer in nurseries | Consider delaying Fertilizer Efficiency | One player considered it less necessary in that situation |
There is no need to treat this as a permanent rule. A player who is not yet depending on fertilizer may get more immediate value elsewhere. The key is to match the upgrade to the resource the factory actually consumes.
Keep Production and Conveyors Aligned
Production speed is powerful, but it changes ratios. That is the central warning repeated in the community discussion. If a machine produces or consumes faster after an upgrade, a line that once matched neatly may become starved or backed up.
One player preferred waiting for a total 100% production increase, described as four 25% upgrades, because doubling rates made the ratios easier to reason about. Another preferred taking production and belt speed together to level 2, producing faster without completely disrupting ratios.
Conveyor speed is especially valuable once a factory must move more than 60 items per minute. Before that point, upgrading belts may not solve a current problem. After that point, it can become difficult to compensate for limited transport capacity by simply adding machines.
| Upgrade approach | Reported benefit | Reported tradeoff |
|---|---|---|
| Delay production speed until +100% | Ratios remain simple because rates double | Slower access to added output |
| Raise production and belts together | Faster production while keeping capacities closer | Requires spending points across two upgrades |
| Favor belt speed | Addresses transport limits that machines cannot fully compensate for | May be unnecessary below 60/min transport needs |
| Add more machines instead of speed | Can preserve existing ratios | Uses more factory space and equipment |
Before choosing Factory Efficiency, inspect the entire chain. Check whether inputs can arrive at the faster rate, whether outputs can leave, and whether heat supply can support the line. If the answer is no, speed can expose the bottleneck rather than fix it.
A Practical Upgrade Order
A good upgrade order is not a universal checklist. It should follow the stage of the factory and the problem in front of you. Still, the sources support a reliable sequence: reach automation, use efficient wholesale income, build toward cauldrons, then use speed upgrades only where the logistics and fuel systems can sustain them.
Early progression is described as a sprint toward automation. The recommended minimal objectives are unlocking the cash register, Nursery, purchase portal and dispatch portal, then bandage wholesale. Avoid overbuilding while manual stocking, refilling materials, and customer checkout still consume attention.
At this stage, repeated simple bandage production through blueprints can support wholesale saturation. The storefront may eventually become part of a larger revenue strategy, but focusing strictly on wholesaling through the mid-game can reduce the distraction of customer happiness and quests.
| Factory stage | Main focus | Upgrade guidance |
|---|---|---|
| Early manual factory | Reach core unlocks and automation | Favor Fertilizer Efficiency if it supports wholesale margins |
| Bandage wholesale | Saturate simple passive income | Continue fertilizer-focused upgrades |
| Early production expansion | Preserve workable line ratios | Avoid isolated production-speed increases |
| Higher transport demand | Move more than 60/min | Prioritize conveyor speed when belts are the limit |
| Cauldron transition | Bootstrap bronze production | Accept initial inefficiency; cauldrons are the key mid-game target |
The first bronze line may be inefficient, and that is acceptable according to the progression guide. The important goal is reaching cauldrons rather than perfectly optimizing every early machine. Save ratio tuning for the point where the underlying production chain is established.
Review Upgrades Against Your Current Bottleneck
Use a short review before spending points. It prevents an upgrade from solving a theoretical issue while creating a more expensive real one.
- If shelves, refills, and checkout are consuming your time, prioritize the route to automation instead of an optional upgrade.
- If wholesale profit is weak because fertilizer is costly, examine Fertilizer Efficiency.
- If a speed upgrade would make machines request more inputs than belts can carry, improve logistics or delay production speed.
- If faster devices strain fuel, consider Fuel Efficiency alongside Factory Efficiency.
- If transport demand is above 60/min, Conveyor Belt Speed deserves more attention.
- If your production and belt speeds differ, bring them back into a workable relationship before expanding the line.
The upgrade panel also offers Sales Ability, Negotiation Skill, Customer Management, Alchemy Skill, Throwing Efficiency, and Relic Knowledge. These can be appropriate when their stated systems are your current limiting factor: shop profit, purchase contract amount, quest rewards, extractor output, throwing rate, or relic withdrawal bonus.
Do not assume that shop-facing upgrades are automatically better than factory upgrades. Wholesale income is described as easier passive income than managing customer happiness or quests during the mid-game. That makes resource efficiency and stable production especially useful while the factory is still advancing.
FAQ
What are the best early upgrades in this alchemy factory upgrade guide?
Fertilizer Efficiency and Fuel Efficiency are the strongest early recommendations in the available player guidance. Fertilizer Efficiency is especially useful when fertilizer costs affect wholesale margins, while Fuel Efficiency can help when faster production increases heat demand.
Should I upgrade Factory Efficiency immediately?
Not necessarily. Players warn that production speed changes ratios and can make a balanced line awkward. Check input supply, conveyor capacity, output handling, and fuel use first.
When should I upgrade Conveyor Belt Speed?
Conveyor speed becomes more valuable when the factory needs to transport more than 60 items per minute. It can also be worth raising alongside production speed so machines and belts remain aligned.
Is it better to focus on the shop or wholesale income?
During the mid-game, bandage wholesaling is recommended as a simpler passive-income focus than managing customer happiness or quests. The storefront can be reintroduced later to maximize revenue.
Do I need a perfectly efficient first bronze line?
No. The available progression advice says the first bronze production line will be highly inefficient, and that is acceptable because reaching cauldrons is the more important mid-game objective.
