So you made it to Adventurer Rank 16 in Genshin Impact and are looking for a group to team up with and take on the world. Co-op is a similar, yet restricted version of the main game, focusing on open world engagements and dungeon runs.
Co-op content and limitations
When in co-op, players can only do Abyssal Domains, Ley Line Outcrops, Commissions, and even the open-world bosses.
Keep in mind that when you join another player’s world, you cannot pick up items, open chests, or make offerings to the Statues of the Seven. Co-op is currently restrictive and operates as a social model for Genshin Impact to test strategies for upcoming dungeons, rather than a fleshed-out experience.
The party limit is still four, and depending on how many players join an instance the number of heroes at your disposal will vary. In a game with two players, each player will have two heroes for use. In a game with three players, the host will have access to two heroes and the other players will choose one hero to play. In a full lobby of four players, each player is tied to one hero, emphasizing teamwork and synergy.
The more players that are in a lobby, the more communication is required to be successful and to pull off chain attacks.
Genshin Impact is still in its infancy but already has so much to offer for a free-to-play title. Developer miHoYo has already stated that they have plans to continue expanding Genshin Impact with new content regularly, and it its co-op receives more support (and shared or instanced loot becomes a reality), then there could be a flourishing community for dungeon raids.
