Which upgrades help when advanced production becomes expensive?

Fuel Efficiency lowers fuel costs and becomes useful around Blast Potions and Paradox Crucibles. Alchemy improves Alembic and Extractor output, helping production chains that depend on those devices.

When should I prioritize Relic Knowledge?

Relic Knowledge increases the experience gained from consuming relics. It becomes especially useful when feeding higher relics such as Venus, Mercury, Luna and Sol into the altar; Alchemy is another late-game priority when Alembic output limits the potion chains.

Can I reset an unsuitable upgrade allocation?

You can reset your upgrade points repeatedly. The price rises with repeated resets until it reaches a maximum of 10 Gold, so account for the reset cost before reallocating.

Turn spare products into knowledge

Feed items into a Knowledge Altar to gain experience and raise your Knowledge Level. Since 1.0, the altar accepts any item; Relics grant additional experience.

A Knowledge Altar costs 24 Stone to build. Its role is to break down items into alchemical knowledge.

Build an experience loop

Produce relics, sell the portion needed for shop income, and feed the remaining relics to the Knowledge Altar. Spare ordinary items can also become experience.
Spend the resulting skill points on the bottleneck you are facing. Customer Management is a useful early choice because it improves quest rewards; Fertilization Efficiency becomes useful when fertilizer demand grows.
During the middle stages, increase Logistics Efficiency and Factory Efficiency together, a point at a time: the former improves belt speed, while the latter changes machine and cauldron speed and heat behavior.
