Genshin Impact Co-op: How to Unlock It and Play Together

Genshin Impact co-op opens at Adventure Rank 16 and lets up to four players share one world, as long as everyone plays on the same server. Together you can fight bosses, clear Domains and collect Ley Line rewards. Story quests and chests stay with the owner of the world.

How to unlock Genshin Impact co-op

Reach Adventure Rank 16. Before that, the Co-Op Mode button in the Paimon Menu is locked: you cannot join anyone, and nobody can join you. Quests and exploring are the quickest sources of Adventure EXP early on, and our Genshin Impact beginner guide covers that climb.

Once it is open, the Co-Op Mode screen (F2 on PC) lists worlds you can ask to join and has a search box for a player's UID. Genshin Impact multiplayer is always one player's own world with guests in it: one player hosts, the others visit.

How to play co-op in Genshin Impact with friends

1. Check the server. You pick a server on the login screen (America, Europe, Asia, or TW, HK, MO), and each one keeps separate progress. Players on different servers cannot meet. The platform does not matter: PC, mobile and console players on the same server play together.
2. Add each other. Open Friends in the Paimon Menu and search for your friend's UID, the number shown in the corner of the screen.
3. Send a request. Select your friend in the Friends list and choose Request to Join, or search for their UID on the Co-Op Mode screen.
4. The host accepts, and you load into their world.

If you are starting new accounts to play together, agree on one server first. Progress cannot be moved from one server to another.

The host decides how open the world is. The co-op settings offer three choices: let players join directly, ask for approval first, or refuse all requests. Approval first is the sensible default.

Party size depends on the number of players. With two players, each controls two characters. With three, the host has two and each guest has one. With four, everyone plays a single character.

One rule surprises new players: you can only join a world whose World Level is the same as yours or lower. A veteran can visit a new player's world, but not the other way around.

What you can and cannot do in another player's world

As a guest, you can:

• Fight open-world bosses and enemies, and take on Ley Line Outcrops with the host.
• Enter Domains together, including the weekly boss Domains.
• Pick up plants, ores and local specialties. They come out of the host's world, so read the section on manners below.
• Join the co-op activities that many events include.

You cannot:

• Play story quests. Archon Quests and character Story Quests are single-player, and while the host is in certain quest steps the world cannot be joined at all.
• Open chests. Only the host can.
• Collect oculi in the host's world.
• Enter the Spiral Abyss, which is single-player.

Domains and bosses in co-op

Rewards are personal. Each player spends their own Original Resin and receives their own drops, so nobody can take your loot and you cannot take theirs. Co-op does not give more rewards per Resin. What it saves is time, and it makes a hard fight possible for an account that could not win it alone. Our guide to daily commissions and Resin shows where that Resin is best spent.

To start a Domain as a group, the host opens the Domain's door and picks the difficulty, and the guests confirm. If you have no group, the Match button on the Domain's entrance screen pairs you with other players on your server.

Two things change in a full party:

• Enemies have more health when more players are present, so four unbuilt characters are not faster than one built team.
• Everyone has a single character, so nobody can swap to a healer. Agree on roles before you enter: one healer or shielder, one Anemo character such as Sucrose, Kazuha or Venti to gather enemies, and damage dealers whose elements react with each other. Four players who each bring their favorite damage dealer make the slowest team.

The in-game text chat is enough to agree on who brings what before the door opens.

Co-op manners that keep you welcome

• Ask before you take. Ores and local specialties take days to come back, and the host may need them for an ascension. Say what you want and how many when you join.
• Wait for everyone. Do not start the boss while a teammate is still loading or changing characters.
• Stay for the run. Leaving in the middle of a Domain leaves the team short.
• The host has the last word. It is their world. A host whose request is ignored can remove a guest from the co-op screen.

Never enter your password anywhere to "get help" from another player. Co-op needs only a UID. Nobody who wants to play with you needs access to your account.

Frequent questions about co-op

Why can't I join my friend's world?

Go down this list: both of you are Adventure Rank 16 or higher, you are on the same server, their World Level is not higher than yours, their world is not full, they are not in the middle of a story quest, and their co-op setting allows requests.

Can you play story quests in co-op?

No. Story quests are single-player. Co-op is for bosses, Domains, Ley Lines, exploring and events.

Who gets the chests in co-op?

The host. Guests cannot open chests in another player's world.

Is Genshin Impact co-op cross-platform?

Yes. PC, mobile and console players can play together when they are on the same server.
