Achievement completion is easier when it is split into route work, targeted experiments, and final verification. Steam currently lists 27 achievements for Sephiria’s base product, AppID 2436940. The official list is the authority for names and descriptions; a completion order and any hidden route still require current testing. Keep the separate demo AppID 2686970 out of the checklist.
Learn progression
Earn ordinary chapter and combat targets while learning the core loop.
Target conditions
Use a build, boss route, inventory plan, or party arrangement for specific goals.
Finish carefully
Handle co-op and completion conditions only after the route and evidence are clear.
Confirm Steam
Check the client result and record delay, synchronization, or unresolved behavior.
Build the checklist from Steam
Copy the current official name and description, then classify the target as progression, combat, collection, boss, co-op, or completion. Add a route suggestion only after understanding what the description requires. If the description is vague or hidden, label the route as a lead and say what evidence would confirm it.
The Achievement Guide contains the detailed record format. This page supplies the order and the links to Chapters, Builds, Bosses, and Multiplayer. Avoid copying full strategy text into every achievement row.
Route ordinary goals first
Use a normal chapter run for goals that match progression. A first clear teaches enemy pressure, inventory space, weapons, and boss movement. Chasing an unverified collectible or hidden action too early can end the run without clarifying the condition. Record the result and reserve a separate attempt for the targeted goal.
Prepare targeted attempts
For a combat goal, choose a weapon and checkpoint that make the condition visible. For a collection goal, protect the route and inventory from the target’s uncertainty. For a boss goal, record phase, mode, and restriction. For co-op, agree on party size, host context, and what every player must see. The current game should confirm the result before the page calls the route complete.
Handle missing unlocks
A progress change, a client notification, and a synchronized achievement are not necessarily the same event. Check the official description, mode, save state, and current update before repeating a risky route. If the outcome is inconsistent, label it unresolved and link to Updates rather than publishing a guessed workaround.
Keep a completion ledger
For every target, store official wording, condition type, planned route, attempt date, version, mode, result, and confidence. Use confirmed in current game only when the action was reproduced and the Steam client displayed the unlock. Use community lead when a dated player report suggests a route that has not been reproduced. Use unresolved when a missing trigger could still be a save, branch, or synchronization issue.
This ledger makes the final pass safer. If a weapon update affects a combat target, retest the weapon page and keep the achievement row linked. If a boss update affects a restriction, retest the encounter and not the entire completion route. If the Steam list changes, update the official wording and keep the prior evidence marked historical.
Completion is not speedrunning
The fastest route can be a poor completion route if it risks a long save or hides a condition. Prefer a stable build, a clear fallback, and a route that another player can reproduce. Add optimization only after the condition is confirmed. A shorter, accurate checklist is better than a long guide that promises hidden triggers without proof.
If the target is uncertain, make the uncertainty visible before the route recommendation.
That simple label protects the rest of the completion list from a single unsupported claim.
It also gives readers permission to stop before a risky, unconfirmed detour.
Use the same stop rule for co-op and boss attempts.
Then update the ledger before starting another route.
