Co-op Multiplayer

Dimraeth supports 1 to 8 players in seamless drop-in and drop-out co-op. The developers recommend 1 to 4 players "for the best experience". It is the same game either way: combat and boss design are described as working solo or in a group, and there is no separate co-op mode to enter.

What Travels Between Worlds

Characters belong to you, worlds do not. The split matters as soon as you join a friend.

So you can carry a character into someone else’s world and keep everything it has earned, but that world’s story state, the allies recruited there and anything built there stay with its owner. Base building and farming are world-side investments, not things you pack up and take with you.

Playing Together

• XP is shared with every player in the area, a rule recorded in July 2023.

• Monsters scale with the number of players. A 2023 note scaled monster difficulty to the player count on the server; a May 2024 note replaced that with scaling against players nearby, which is the version that stands.

• Some potions can be thrown to heal an ally in the middle of a fight, which makes crafting a party utility and not only a solo one.

• Spells can be cast on yourself or on party members from the avatar overlay on the heads-up display, added in June 2024.

• Every archetype has a skill tree no other archetype can use, and only five spells can be equipped at a time, so a group of eight covers far more of the spell pool than any one player can.

Difficulty and Who Can Join You

Three world and player difficulties, Easy, Moderate and Hard, have existed since July 2023, and Moderate became the default setting in April 2025. Difficulty levels also appear on the list of changes arriving with Early Access, so they may have been revised, but they are not new.

Difficulty is a hard partition on multiplayer: a March 2024 note states that the server is locked to its difficulty mode and that characters on different difficulties cannot join each other. Difficulty changes rules and not only numbers, with friendly fire on Hard and inventory emptying on death at harder world difficulties. A December 2024 fix also made single player worlds unjoinable. As of 2026-09-12 no later first-party post revises any of this.

Party Size History

The party cap has moved. An August 2023 note added parties of "Up to 6 Players" granting "a maximum of +50% XP bonus". By June 2024 the team reported playtesting eight person multiplayer internally. The figure published for Early Access is 1 to 8.

The +50% XP bonus was only ever stated at the six player cap. As of 2026-09-12 no first-party source restates it for an eight player party, so the current value of any group XP bonus is unknown and the old number should not be carried across.

Lobbies, Parties and Social Features

A multiplayer lobby system was one of the headline items of the technical playtest held in late January and early February 2026, alongside full controller support and Steam Deck support. Those entries come from patch notes and playtest briefings: they establish that a feature existed when it was written about, not how it behaves in the Early Access build.

What Co-op Is Not

All of the following were verified on 2026-09-12 and are stated by the developers rather than inferred.

• No dedicated servers and no private servers. Sessions are peer to peer with one player hosting.

• No local play and no split-screen.

• Not an MMO. The player ceiling is 8, not a shared persistent world.

• No cross-difficulty play, per the March 2024 note above.

• No console version and no announced console plans, so co-op is between machines running the Steam build. See Release and Early Access.
