Sephiria Co

Sephiria supports online co-op for up to four players, and teams can trade items and revive fallen companions while exploring the tower together. That combination changes the maths of a run more than the extra damage does.

What co-op actually gives you

Three things, per the official feature list:

• Up to 4 players exploring the tower together
• Item trading between teammates
• Reviving fallen companions

Reviving is the big one. In solo play, a death ends the run. In co-op, a death is a setback that a teammate can undo — which means a co-op team can take risks that would be reckless alone.

Item trading matters for a different reason. Because Artifacts are only as good as where they sit in your inventory, an Artifact that is dead weight in your bag might be exactly what a teammate's build needs. Trading turns a bad drop into a good one.

When co-op helps

• You want to see later chapters sooner
• Your group has different weapon classes, so trades have somewhere useful to go
• You are comfortable enough with the inventory system to know what to ask for

When to stay solo

If you are still learning, play solo first. Reviving papers over the exact mistakes you need to notice — badly placed Artifacts, committing to the wrong upgrade tree, poor dodge timing. A co-op team will carry you past those without you learning why they were problems.

Come back to co-op once you can reliably reach chapter 3 on your own.

Still to verify

Matchmaking specifics, whether progression and Talent unlocks are shared or per-player, and how scaling works with player count are not yet confirmed. We will add them once tested rather than assume the usual conventions.
