WHERE & HOW TO FARM
Where to farm
Campaign → Hard Mode → your highest cleared chapter.
Core Data is the main reason to use Hard Mode consistently: completed Hard Mode sorties award it, and the same entries can also produce retrofit prints. The farming reference reports that stages within one Hard Mode world give the same Core Data, so choose among them based on the blueprint category you need. If no print is a priority, use a stage you can clear comfortably in your highest available chapter.
Unlock Hard Mode and clear the chapter you intend to farm.
Have daily entries remaining.
Use a fleet capable of completing the selected stage.
Know what you want to purchase with Core Data, if you are saving toward a shop item.
Open Hard Mode and select the highest chapter you can clear safely.
Compare stage rewards within that chapter and select one whose blueprint type is useful, if you have a print target.
Set a formation that satisfies the stage’s fleet restrictions.
Complete the stage and collect the result, including its Core Data award.
Check your Core Data balance and review the Core Data shop for the item you are saving toward.
Spend Core Data only when the desired purchase is available and fits your plan.
Repeat on remaining daily entries, adjusting the stage if your blueprint need changes.
Farming tips
The same chapter can serve both goals: Core Data accumulation and a specific retrofit print hunt.
Hard Mode entries are limited, so make a quick reward check before each sortie.
Repeat, collect and use
Limited daily farm. Core Data is awarded through clears, but the activity has a daily entry limit; the available amount and shop stock should be checked in-game.
Common mistakes
Selecting a lower chapter without a reason when a higher one is clearable; compare the current chapter options.
Ignoring blueprint rewards while farming Core Data; a useful stage can advance both goals.
Leaving the shop unreviewed; check whether your saved currency can now buy a needed item.
When to stop or switch
Stop after using the day’s entries or reaching the Core Data purchase you were saving for; continue only if another shop item remains a priority.
