WHERE & HOW TO FARM
Where to farm
Campaign → World 12 → stage 12-4.
Choukai is a random ship drop associated with Campaign 12-4. Treat this as a focused ship hunt: clear the stage, check the result, and continue only while she remains a roster goal. The stage also pays its ordinary campaign rewards, but no fixed number of runs guarantees the ship.
Bring a fleet that can clear the stage and its boss consistently.
Keep enough oil for repeated sorties and room in ship storage.
Open the 12-4 stage screen and review its displayed rewards before committing oil.
Choose a fleet that can handle the stage reliably; avoid weakening a clear team solely to reduce oil unless it remains safe.
Start the sortie and advance through the map until the boss fleet is available.
Defeat the boss and complete the stage.
Review the results and ship inventory for Choukai; also collect any pending mission or milestone reward shown by the game.
If she did not appear and remains your target, return to 12-4 for another sortie.
Farming tips
Use the stage’s current reward display as the check for what this sortie can award.
A stable clear saves time and repair resources; revisit fleet efficiency only if your team already clears comfortably.
Repeat, collect and use
Repeatable campaign farm. Choukai’s appearance is random, so there is no guaranteed run count. Stop the ship hunt once you obtain her or another account goal becomes more useful.
Common mistakes
Assuming a clear guarantees Choukai; check the result and continue only if the target is still needed.
Taking an unreliable understrength fleet to save oil; use a team that can finish safely.
Leaving rewards or milestone claims uncollected; inspect the post-sortie screens before returning to the map.
When to stop or switch
Stop after Choukai joins your dock, or switch to a higher-priority campaign target when the oil and time are better spent elsewhere.
