Sephiria Achievements: 27-Item Checklist & Public Requirements

Steam lists 27 achievements: 15 with public requirements and 12 without a public condition. Search the checklist and mark your own progress for this visit; checkmarks do not sync with Steam.

27-achievement checklist

Names and public goals checked against Steam's official list on September 4, 2026. Goal descriptions below are paraphrased.

This manual checklist does not connect to your Steam account or unlock achievements. Marks reset when you leave or reload this page.

Start with a goal you can verify

Choose Public requirement in the filter to see the 15 goals Steam describes. DIY concerns repairing your house; Traveler concerns discovering a hidden room. Ten goals name a boss to defeat, and three name a Hard Mode stage. Search a boss name to find the matching achievement without scrolling through the full list.

Check your personal Steam achievement list before ticking an entry here. This checklist keeps marks only while the page remains open. Steam's global percentages measure how many players have earned each achievement; they do not establish a mandatory route, estimated completion time or difficulty rating.

Hard Mode milestones: Stage 1, 15 and 30

The public conditions distinguish three clears. Search Hard Mode Stage to display them together. Treat the stage number as the goal stated by Steam, not as a number of runs or a character-unlock requirement.

  • Root's Retreat: complete Hard Mode Stage 1.
  • Root's Retreat 15: complete Hard Mode Stage 15.
  • Root's Retreat 30: complete Hard Mode Stage 30.

The 12 entries without a public condition

Choose Public condition not shown to isolate the 12 entries whose description was blank on the public Steam page when checked. These include the Chapter entries, Qliphoth Contractor and Journey's End. The checklist preserves their names but leaves their requirements unknown.

A blank public description does not establish an unlock trigger. Do not infer one from a title or assume that another player's chapter name identifies the same condition. If your personal Steam view reveals more information, use that wording for your own progress; the public snapshot here is not a verified full-completion walkthrough.

Achievements not recording alongside an ERR lobby

TEAM HORAY's Technical Support FAQ describes a specific symptom group: Steam achievements fail to record while a multiplayer room shows ERR, or creating or joining a room does not respond. The developer links those cases to the game failing to connect to the Steam client at launch, often when the client could not update. One locked achievement alone does not prove this is your problem.

Start with the non-destructive checks below. If Steam cannot update, consult the linked official FAQ's full troubleshooting instructions before changing its configuration. This page does not ask you to delete a Steam configuration file, change permissions or edit a save.

  • 1. Close the game and exit Steam. On Windows, check Task Manager to confirm Steam has exited before reopening it.
  • 2. Start Steam directly, allow client updates to finish, and use the Steam menu's update check if needed. TEAM HORAY notes that a network accelerator or VPN can interfere with client updates; record whether one is in use.
  • 3. Launch Sephiria from your Steam Library and check both the lobby symptom and your personal achievement list. This does not guarantee a missed achievement will unlock retroactively.
  • 4. If the problem persists, collect Player.log and Player-prev.log soon after reproducing it, plus the achievement name, version and symptom. The FAQ lists team.horay.game@gmail.com for support. Review diagnostic files for personal information before sending them.
