WHERE & HOW TO FARM
Where to farm
Hard Mission 3-3, unlocked through Normal chapter progression.
Hard 3-3 is listed as a Serika Eleph node. Unlock the Hard chapter through campaign progress, verify the reward preview, then spend its daily attempts while Serika is a roster priority. The Eleph accumulates toward promotion; star upgrades also require Credits and later weapon growth has additional costs.
Progress far enough in Normal Missions to unlock Hard 3-3.
Have AP and a team capable of clearing the node.
Serika must be a student you intend to promote.
Open Hard 3-3 and check that Serika Eleph appears in the reward preview.
Clear the stage, meeting its conditions for a three-star rating if possible.
Use sweep on later attempts once the stage is eligible.
Spend the node’s available daily attempts while Serika remains the target.
Track Serika Eleph in her student page as it accumulates.
When the promotion requirement is met, open student development and confirm Credits are available.
Promote Serika, then reassess whether further Eleph remains part of your plan.
Farming tips
Hard stages consume AP and have a limited number of daily attempts; plan around that cap.
Student promotion uses that student’s Eleph and Credits, so check both before expecting an immediate star-up.
Repeat, collect and use
Repeat up to the node’s daily attempt limit while Serika Eleph is wanted. This is a limited daily farm, not unlimited sweeping. Stop when the intended promotion is funded or Serika is no longer a roster priority.
Common mistakes
Sweeping without checking the current preview: confirm the Serika Eleph reward first.
Expecting each attempt to produce enough Eleph for a promotion: treat the node as incremental collection.
Ignoring Credits: promotion requires Credits in addition to Eleph.
When to stop or switch
Stop when you reach the planned star promotion threshold or decide another student should receive your limited Hard attempts.
