Player limit
Sephiria supports online co-op for up to four players with shared exploration, item trading and teammate revival.
How to start and join co-op
The Mysterious Door unlock timing and the exact steps after Create or Join by Code remain community guidance rather than first-party instructions.
Complete the opening progression
A community walkthrough reports that each player should finish the Prologue or tutorial before looking for multiplayer. Treat the unlock timing as community guidance.
Return to Bunnyville
Look for the large stone Mysterious Door and use its Open prompt to reach the Multiplayer screen.
Create or Join by Code
Current player-provided 1.0.23 captures reviewed on the reference page show both actions. The code format and post-button screens are not documented here.
Use a Steam invite if needed
The community walkthrough describes Steam invites as an alternate joining route after the host creates the lobby.
Progression and session rules
Host migration, save ownership, unlock sharing and reconnect behavior are not established by the official sources reviewed so far.
Detailed host, progression and reconnect rules require current-version community testing.
Known connection notes
Official 1.0.23 notes say rare combat disconnections and occasional disconnections while selecting a Miracle were improved.
Official 0.7.9 notes fixed client-position synchronization in sessions with three or more players, excluding the host.
Reversible troubleshooting
Match versions
Confirm that every player has the same installed Steam build.
Recreate the lobby
Let the host create a fresh lobby and resend the code or Steam invite.
Restart before changing files
Restart Sephiria and Steam before considering any configuration or save action.
Protect the save
None of the reviewed sources recommends deleting save data to repair a multiplayer lobby.
