Player question
How do I track every Sephiria achievement without following guessed unlock conditions?
Sephiria has 27 Steam achievements. Steam publicly states the requirement for boss victories, Traveler and the Root’s Retreat Stage 1, 15 and 30 thresholds, while several other entries are shown only as titles. Use the public requirement as the plan for a run, and treat a title-only entry as a progress marker rather than evidence for an exact hidden trigger. The checklist below keeps that distinction visible and stores your marks only in this browser.

Progression milestones
Steam lists these milestones, but some do not expose a public requirement on the global-achievements page.
Boss milestones
The condition shown here is the requirement displayed by Steam, not a combat strategy or a claim about a boss pattern.
Discovery milestones
Use the title and any public Steam condition to choose a search target without turning a hidden requirement into a guessed walkthrough.
Hard Mode milestones
These are the three public Root’s Retreat thresholds currently exposed by Steam.
01Start with the official list, not a guessed 100% route
Steam’s Sephiria page currently lists 27 achievements. That number is useful for completion tracking, but it does not make every online “all achievements” walkthrough equally reliable. Steam exposes a short requirement below some achievement titles, while other entries have no public condition on the global-achievements page. This guide preserves that difference instead of converting a title, an icon or a community theory into a step-by-step claim.
The tracker groups the official list by the decision a player can make: progression milestones, boss milestones, discoveries and Hard Mode thresholds. It is a planning view, not an account connection. Mark an item only after Steam has awarded it, then use the official condition to decide what deserves attention in the next run.
- Public requirement: Steam states an action or a named clear condition.
- Title-only entry: Steam shows the achievement name, but not a public requirement on its global list.
- Personal mark: stored in this browser only; it does not read Steam or game-save data.
02Turn visible requirements into a focused run plan
The public boss entries identify several clear targets, including the Mole Chief, Pillager Leader, Mad Scientist, Askard, Demolition Expert, Shadow Blade, Guardian of the Library, Guardian Demon of Qliphoth, Mind-Eater Root and the second Guardian Demon of Qliphoth. A named Steam requirement confirms the target; it does not confirm its attack pattern, chapter placement, recommended weapon or an optimal build. Those details need their own current-version evidence before they become strategy advice.
For discovery, Traveler is the clearest official objective: find a hidden room. Pair it with the Secret Rooms guide rather than assuming a fixed spawn count or a guaranteed reward. For difficulty progression, Steam explicitly tracks Root’s Retreat at Stages 1, 15 and 30. Treat each threshold as a separate readiness check: record the active Hard Mode elements, weapon, board and outcome instead of copying a final-screen build without its conditions.
03Do not infer a condition from a poetic title
Entries such as Chapter I, Soul Plan, Seal and Journey’s End are shown by Steam, but the global list does not display a public condition under each of them. They may be useful signals that your progress is moving forward; they are not permission to publish an exact quest, dialogue, item or ending requirement. This is especially important for players who want to avoid spoilers or avoid repeating a run based on an old claim.
If you use a community walkthrough to investigate a title-only entry, keep the observation separate from the official record. A trustworthy report should include the game version, its before-and-after achievement state, relevant chapter or mode, and an uncropped result screen. Reproduce the sequence before presenting it as a current unlock route, because patches can change progression behavior or localised wording.
- Reliable: “Steam currently lists this achievement title.”
- Reliable: “Steam publicly states this listed clear condition.”
- Not established here: a hidden prerequisite, drop rate, route or ending choice that Steam does not disclose.
04Use a completion log that can survive a patch
Keep your own compact record beside the checklist: game version, achievement title, Solo or Co-op, Hard Mode stage when relevant, and the moment Steam awarded it. This creates a useful trail when a later patch changes an unlock or when a guide uses a different localized title. A screenshot of the achievement toast helps, but the version and run context are what make the result reusable for another player.
For a blocked achievement, first distinguish whether it has a public Steam requirement. If it does, return to the directly related system—hidden rooms for Traveler or Hard Mode preparation for Root’s Retreat. If it does not, do not replace missing evidence with a fabricated checklist item. The accurate next action is to verify the current version or submit a reproducible observation for editorial review.
