Summary (AI)
Patch 5.4467 for Alchemy Factory introduces a major overhaul to the conveyor system, improving stability and performance at high speeds. Several crafting recipes have been reworked, notably for Unstable Catalyst, Black Powder, Star Dust, and Advanced Athanor materials, with changes affecting some existing save files. The Advanced Athanor now supports catalyst modifiers to customize recipe outputs, and the Cauldron's output multiplier has been removed to balance late-game product generation. Additional adjustments include reduced heat consumption for the Steam Heating Pad, increased stack size for Bronze Ingots, removal of the Catalyst tag from certain items, new decorative objects, and various bug fixes and optimizations. Players using older saves may notice altered Cauldron outputs due to recipe updates.
Tip: expand all for quick scanning.
- We have kept the previous patch available on Steam. If you prefer the previous patch, you can switch back to v0.4.4.4323 manually.
- Reworked the recipes for Unstable Catalyst, Black Powder, and Star Dust.
- Due to recipe changes, Black Powder's sell price and heat value have both been doubled.
- Updated the Black Powder icon.
- Updated the Star Dust icon and model.
- Reworked all Advanced Athanor recipes: Silver Powder, Obsidian, Lapis Lazuli and Gold Dust
- Advanced Athanor Rework:
- Unstable Catalyst: Alters product generation probabilities.
- Fertile Catalyst: Doubles product output.
- Resonant Catalyst: Generates all outputs simultaneously.
- Eternal Catalyst: Recipe consumes no materials.
- Previously, the Cauldron applied an additional multiplier when calculating output generation. This multiplier caused certain late-game products (such as Silver Powder and Resonant Catalyst) to be relatively easier to obtain than others, while also suppressing the generation chances of many other products. After further consideration, we decided to remove this multiplier entirely.
- Other Changes:
- Yeast Powder and Gloom Spores no longer carry the Catalyst tag.
