WHERE & HOW TO FARM
Where to farm
Mysterious Alchemy Machine in Haven; select the intended next star-level recipe in the alchemy path.
A standard alchemy upgrade can require a precursor to reach a recipe-specific minimum heat level. Use the selected recipe as your checklist: it identifies the precursor and the heat it needs, while its ingredient list shows what else must be ready. This is a preparation and crafting loop rather than a guaranteed heat-item farm; Clockworks contents vary, and no particular run is promised to supply the heat you need. After the upgrade, the new star-level item starts at heat level 1. Collect heat items and other materials only as needed for the chosen recipe, then use the finished item as your next progression step.
Access to the next star-level recipe you want to make.
The precursor specified by that recipe.
The remaining ingredients listed for the recipe.
Heat items or another available in-game heat source if the precursor is below the displayed requirement.
Open the Mysterious Alchemy Machine and choose the exact next star-level recipe you plan to craft.
Read its entry to identify the required precursor, minimum heat, and additional ingredients.
Inspect the precursor’s current heat and compare it with the selected recipe’s requirement.
If it falls short, gather and apply available heat items or use another in-game heat source until it meets the displayed minimum.
Collect any other missing recipe ingredients through their available in-game sources.
Return to the recipe and confirm the precursor and all listed ingredients are ready.
Craft the upgrade, then check the new item’s heat level; the next star-level item begins at heat level 1.
Farming tips
Recheck the selected recipe whenever you change upgrade paths; heat requirements are recipe-specific.
Keep the recipe open as a checklist so you collect only the ingredients and heat needed for this craft.
Repeat, collect and use
Repeat for each star-level upgrade you want: select its recipe, prepare the named precursor to the listed minimum, gather the remaining ingredients, and craft. Replenish heat items and ingredients as needed; their availability and Clockworks sources can vary.
Common mistakes
Relying on a remembered heat value from a different recipe can leave the precursor short; use the current recipe’s displayed minimum.
Gathering heat before selecting the target recipe can waste effort; choose the recipe first and raise heat only to its requirement.
Expecting the crafted item to keep the precursor’s heat leads to incorrect planning; the next star-level item starts at heat level 1.
When to stop or switch
Stop applying heat once the selected recipe’s minimum is met. Craft when the other listed ingredients are ready; otherwise switch to collecting the specific missing materials.
