Quick Answer: How Do I Play With Friends?

Invite from Steam (or share a lobby code from the pause menu), make sure everyone runs the same game version, and drop in at any campfire. There is no matchmaking for the story โ€” co-op is friends-first by design; the version-mismatch connection error is the most common issue and is fixed by updating.

  • Host: pause menu โ†’ Co-op โ†’ Create lobby. Friends join via Steam invite or lobby code.
  • Version mismatch: everyone verifies their game is updated before connecting.
  • Disconnects: the world persists on the host โ€” rejoining resumes wherever the host is.
  • Bosses: both fights support co-op; see each boss page for group-specific tactics.

Boss Co-op Tactics

  • Ashen Warden: phantoms spawn per player. Assign one teammate to phantom duty; keep the boss on your best-armored player.
  • Magma Tyrant: three players fit per flood platform, four is a shove-fight. Station one player on emergency flask duty.
  • Patience bar (Warden) drains slower with more players โ€” group aggression scales up safely.
Summon items are consumed per attempt, not per player โ€” one Molten Crown covers the whole party's Tyrant attempt.
