Sephiria co-op guide: online multiplayer and roles

What is confirmed

The Steam store lists online co-op for up to four players and specifically calls out trading items and reviving fallen companions. It also describes the game as playable solo, so co-op should be treated as a coordination option rather than a requirement.

Assign jobs before the run

Use simple roles: one player creates space, one watches dangerous targets, one secures a revive window, and one calls out valuable drops. Roles can overlap, but a named responsibility keeps a crowded room from becoming four players making the same decision.

Use voice or quick callouts for boss phases and revive timing. Do not spend a rare item while another player is already moving to a safer route.

Trade with a plan

When a drop does not fit the current weapon route, announce it before taking another item. Keep a short team rule for upgrades: primary weapon fit first, survivability second, novelty last.

The four-player rhythm

A clean room has a caller, a space-maker, a loot reader, and a revive owner. These are responsibilities, not permanent classes; rotate them when the room or weapon route changes.

Before a boss, agree on where players will regroup and which resource is reserved for recovery. That prevents four separate panic decisions when the first player falls.

Co-op build etiquette

Call an item before taking it if another player can use it. Prefer complementary routes: one player controls space, another maintains damage, and a third carries the safer revive window.

After the run, compare what each player actually contributed. A build that looks weaker on a damage screen may have created the room that made the clear possible.
