WHERE & HOW TO FARM
Trinity Technical Notes from Desert Railroad 5–6
Bounty > Desert Railroad stages 5 and 6; inspect the preview for Advanced Trinity Tech Notes.
Before you go
- Clear Normal Mission 3-1 to unlock Bounty.
- Have Bounty Tickets available in the shared pool.
- Plan a Trinity student’s Basic, Enhanced, or Sub Skill upgrade that needs Advanced Tech Notes.
Farming steps
- Open the target Trinity student’s skill screen and identify which non-EX skill needs Notes.
- Select Bounty, then Desert Railroad.
- Check stage 5 and 6 previews for Advanced Trinity Tech Notes.
- Choose a listed stage your roster can clear.
- Complete the entry and collect the Bounty rewards.
- Use remaining tickets on this target only while the planned Trinity upgrade remains the priority.
- Apply the Notes to the intended skill when its other required materials and Credits are ready.
- EX Skills use Tactical Training Blu-rays; Tech Notes are for the other three skill types.
- Desert Railroad’s school pool includes multiple schools, so read the preview for the exact item.
Repeat, collect and use
Repeat with the daily Bounty tickets while this material is needed. The pool is limited and shared; stop when you can complete the selected skill upgrade or when another school’s item is more valuable.
Common mistakes
- Farming Notes for an EX Skill: check the skill type, because EX upgrades use Blu-rays.
- Assuming every stage contains the same school item: verify the selected stage’s reward preview.
- Ignoring the rest of the upgrade bill: collect the Notes alongside the needed artifacts and Credits.
When to stop or switch
Stop when the target non-EX skill has enough Notes; switch to the student’s remaining missing material or another school’s Bounty target.
