Use This Library

Use the achievement tracker to choose the next target, not to stare at completion rate

A tracker helps when it cuts the board into lanes and exposes the next practical run goal.

First read

This page should leave you with one target, not ten

Achievement tracking only matters if it narrows the board into one practical objective for the next run. If the page sends you away with a vague urge to clean up everything, it failed.

When to use it

When this page helps

Open this page when you need to isolate the next locked target by lane, character, or threshold type. It is strongest before you start a run and want one clear board objective instead of a vague promise to clean up everything at once.

Common misread

Most common misread

The dumbest mistake is treating local browser storage like synced account progress. It is not. The other one is mixing baseline character clears with mastery feats and then wondering why the route plan makes no sense.

Boundary

What this page cannot replace

The tracker is not account truth and it is not a strategy guide by itself. Once the target is clear, the next run still needs the correct character guide, damage tool, or boss page underneath it.

Real use example

Use it before you open a new run

A real use case is filtering the board down to one class and one threshold type, picking the cleanest unfinished target, then opening the matching guide or calculator instead of loading into a random run.

How this page works

Use the board like a checklist, not a trophy wall

The clean way to handle achievements is simple. Keep the current board visible, separate the baseline character clears from the high-threshold mastery feats, and stop guessing what a challenge really asks for. This page keeps the whole set in a straight vertical flow, adds exact trigger notes where the rules are explicit, and lets you mark progress locally so your next target is obvious the moment you come back.

Tracker Editorial

The Achievement Board Should Help You Plan, Not Just Count Trophies

A tracker page is low-value if it only mirrors the board. This one is supposed to separate the baseline clears from the mastery checks, show which lane each target belongs to, preserve your local checklist, and point you toward the route or character page that actually helps finish the target.

Why this page matters

The board gets useful only after it is split into clean planning lanes

This page matters because a flat achievement list hides the only structure that players actually need. Out of 22 tracked achievements, some are simple character wins, some are mastery thresholds, and some are long-tail route or challenge checks. Mixing them together turns the board into noise.

The tracker fixes that by separating the lanes, keeping a local checklist, and surfacing the next unfinished target in each family. The point is not to admire completion percentage. It is to stop wasting runs on the wrong goal because the board refused to organize itself.

How this page is verified

The board structure comes from the live achievement dataset and local browser state

Each achievement card on this page is sourced from the current achievement dataset with title, family, character scope, trigger note, planning note, and image metadata. The unlocked state is intentionally separate and stored only in local browser storage on this device.

That means the page can be trusted for the published board and the local checklist you mark here, but it does not pretend to sync with any external profile. The verification model is explicit instead of slippery: site data for the board, local storage for your marks.

  • Family labels are fixed so the board can be filtered by real planning lanes.
  • Trigger notes only appear where the dataset exposes a clean threshold or rule.
  • Checklist progress is local to this browser unless you copy it out yourself.
What actually matters

Character wins, mastery thresholds, and current locked targets are the real reads

The highest-value read on this page is usually not the total completion number. It is which lane is still open and what that lane is actually asking. Character wins measure who is online. Mastery feats measure whether one character can execute a very specific threshold or combat pattern. Those are not the same project.

The local progress cards matter for that reason. They give you the next unfinished target per lane, which is infinitely more useful than one giant undifferentiated list of locked icons. A tracker that cannot answer "what should I chase next?" is not really tracking anything important.

  • Use lane filters first when you want the next realistic target.
  • Use character filters when a run should serve one board slice only.
  • Use locked-only when the checklist is mature and you need the short list fast.
Common mistakes / traps

The bad tracker habits are procedural, not mysterious

The first trap is treating browser-local progress like account sync. It is not. If the browser storage disappears, the checklist disappears with it unless you copied the summary out first. The page tells you this up front so nobody gets to act surprised later.

The second trap is confusing baseline wins with mastery feats. They are different run goals with different failure modes. If you load into a run chasing a mastery threshold while mentally crediting it as "just another clear," you are already planning the wrong route and card priorities.

  • Do not expect the checklist to survive browser-data wipes automatically.
  • Do not read planning notes as hidden rules beyond the published achievement condition.
  • Do not mix baseline character clears with mastery runs in the same planning session unless that overlap is real.

Split the board into clean lanes first. Character wins tell you who is online. Mastery feats are the real threshold checks. The rest is route cleanup and disciplined challenge play.

FAQ

The usual misses are straightforward: mixing baseline wins with mastery feats, forgetting that some checks care about one target only, or clearing browser storage and expecting the checklist to stay.

Does this tracker save my progress?

Yes. The checklist is saved in local browser storage on this device, so your marks stay between visits unless you clear browser data.

Why do some cards show an exact trigger note and others do not?

Only the checks with a clear threshold or explicit trigger behavior get the extra note. The rest are left at the plain board description so the page does not invent rules that are not stated.

Can I track only one character?

Yes. Use the character filter to isolate Ironclad, Silent, Regent, Necrobinder, or Defect achievements, then switch the status filter to locked only if you only care about unfinished targets.

What happens if I lose my browser data?

The local checklist resets. If you care about your current board state, use the copy summary button before clearing storage or moving devices.
