The farming layer of The Piper of Dawn is 100+ magical crops carrying trait modifiers, planted on a farm plot that expands into underground biomes as you push deeper. Those crops are the ingredient side of alchemy: alchemical circles in the biomes convert them into the potions you sell, which makes the farm and the shop one production chain rather than two systems that happen to coexist.
The magical crops
The store page for AppID 3804370 puts the crop count at over 100, and the Farm Sim tag sits alongside Shop Keeper and Base Building for a reason: growing is a production input here, not a decorative minigame. Every crop exists to become something in the alchemy chain.
The crop roster itself is not published on the store page. The count and the modifier system are; individual crop names, tiers, and grow times are not listed as of 2026-09-25.
Trait modifiers
Crops carry trait modifiers rather than a single fixed value, so a better crop changes the potion it becomes rather than simply increasing a number. This is the mechanic that makes crop choice a real decision: under Equivalent Exchange, swapping a crop changes what a brew costs, which changes what the shop can profitably stock.
Trait modifiers are named in the store description but their individual values are not, so this site describes the system and stops there rather than publishing a stat table the developer has not released.
Underground biomes and plot expansion
The farm plot does not stay on the surface. Underground biomes expand the plot downward, and each biome brings its own growing conditions and its own alchemical circles. Depth is therefore the progression axis for this system: it widens the crop pool and widens the conversion pool at the same time.
The number of biomes, their unlock conditions, and the layout of the plot are not published as of 2026-09-25.
How crops reach the shop
Crops are harvested, routed through the alchemical circles in the biomes, and brewed at the Tree of Life into the potions you stock in the Diamond City shop. Peoplesprouts assigned as Farmers run the growing stage and those assigned as Manufacturers run the conversion stage, so staffing decisions affect the farm directly rather than only the storefront.
The alchemy system page covers the conversion rules, and the Peoplesprouts page covers the roles that run them.
