WHERE & HOW TO FARM
Where to farm
Campaign → Hard Mode → a stage listing the retrofit blueprint type you need.
Hard Mode sorties award Core Data and stage-specific retrofit blueprints. Because entries are limited each day, decide which retrofit print category matters before choosing a map. The highest stage is not automatically the right one if its blueprint rewards do not match your upgrade plan. Use the in-game Hard Mode reward display to select the appropriate chapter and stage, then spend available entries on clears you can complete reliably.
Identify the blueprint category needed for a specific retrofit.
Bring a fleet that meets the stage’s restrictions and can clear it.
Open the retrofit or ship upgrade interface and identify the print category required.
Enter Hard Mode and inspect stage reward details for the chapters you have unlocked.
Choose the highest stage you can clear that lists the needed blueprint category.
Check fleet restrictions and stage conditions, then set a dependable formation.
Complete the sortie and review the results for blueprints and Core Data.
Claim any associated task reward shown after the clear.
Use the prints in the relevant retrofit interface, then repeat the matching stage on another available entry if more are needed.
Farming tips
Hard Mode stage rewards differ; confirm the print type each day before using an entry.
When two available stages both fit your print need, favor the higher chapter if it remains a safe clear and offers more Core Data.
Repeat, collect and use
Limited daily activity. Entries refresh according to the game’s daily schedule, and blueprint drops are random rather than guaranteed.
Common mistakes
Choosing a stage for its chapter number without checking the blueprint category; inspect its reward panel.
Spending entries on a stage your fleet cannot reliably finish; use a proven clear team.
Expecting a print from every run; track inventory over multiple daily clears.
When to stop or switch
Stop for the day when entries are used or the needed retrofit prints are collected; switch to a different blueprint stage when the next retrofit requires another type.
