WHERE & HOW TO FARM
Where to farm
Resource > Harvest Prime; spend its building materials in Wilderness upgrades.
Harvest Prime is a targeted source of materials for Wilderness construction and upgrades. Its value is highest when a specific building improvement is still available and will move account progression forward. Check the Wilderness upgrade screens first, especially the Paleohall, since its levels gate upgrades to the Dust Bell Tower and Sharpodonty Market. Once the core production buildings are fully upgraded, continuing this farm no longer advances that passive-income goal.
Progress through the story until Harvest Prime is unlocked.
Unlock the Wilderness and identify the next building upgrade you can make.
Have Activity available for Harvest Prime runs.
Open the Wilderness and inspect Paleohall, Dust Bell Tower and Sharpodonty Market upgrade requirements.
Choose one available upgrade that improves or unlocks a useful structure.
Note the specific building material still required.
Enter Resource > Harvest Prime and inspect the stage rewards.
Select the highest difficulty your team can clear consistently.
Run the stage and check the material total in the Wilderness upgrade screen.
Apply the upgrade as soon as its requirements are met, then reassess.
Farming tips
Prioritize Paleohall when it gates production-building levels.
This farm serves construction progression; do not stockpile building materials after the relevant structures reach their caps.
Repeat, collect and use
Repeat only while a useful Wilderness building upgrade remains and Harvest Prime materials are required. It is an ongoing stage, but its account-income purpose ends when core structures are fully upgraded.
Common mistakes
Running it without a target upgrade: check the building requirement first.
Upgrading a non-gating structure while Paleohall blocks production levels: resolve the gate first.
Continuing after production buildings are capped: redirect Activity to character or Psychube growth.
When to stop or switch
Stop once the selected upgrade is complete or core resource buildings are fully upgraded; switch to the resource stage matching your current roster need.
