If you’ve ever stared at a level 90 domain you can’t beat solo, or gotten tired of farming artifacts alone for hours with nothing but bad rolls to show for it, you’re not alone. Figuring out how to co op domains in Genshin Impact is one of the best quality of life upgrades you can make once you hit AR 45, when 5-star artifact drops become guaranteed on full resin runs. I’ve run over 300 co op domain sessions in the last year, both as a host and a guest, and I’ve picked up all the small tricks that turn messy, failed runs into quick, loot-filled wins with minimal frustration for everyone involved. Even if you’ve had bad co op experiences in the past, a little know-how makes all the difference.
Pre-Requisites You Need to Co Op Domains in Genshin Impact
Before you jump into a co op domain run, there are a few basic requirements you have to meet first, no matter if you’re hosting or joining as a guest. AR 16 is the minimum to access co op mode at all, but most high-value domains that drop 4 and 5-star artifacts or ascension materials require AR 30 or higher to enter, even as a guest. You won’t be able to join a run for a domain that’s above your account’s allowed level, even if a friend invites you directly.
You need at least 20 original resin per run to claim rewards, same as solo runs, though you can join runs for fun without claiming loot if you’re helping a friend or practicing mechanics. Condensed resin works too, and gives you double the rewards just like it does in solo mode, so it’s a great option if you’re farming the same domain for hours. Hosts must have already unlocked the domain by visiting its physical location in Teyvat first – guests can join even if they haven’t found the domain yet, which is a handy hack for new players who haven’t explored all regions yet. Crossplay is enabled across all platforms, so you can team up with friends on PC, mobile, or PlayStation with no extra steps needed.
Step-by-Step Process to Start or Join a Co Op Domain Run
Once you meet all the pre-requisites, starting or joining a run is straightforward, even for total beginners. If you’re hosting, you can either open the Adventurer Handbook, navigate to the Domains tab, select the domain you want to farm, and click the “Match” button to open your session to random players, or send direct invites to friends on your friends list. You can adjust your world settings to allow direct joins, or require players to send a request first, which is helpful if you want to vet team comps before letting people join.
If you’re joining a run as a guest, you can either accept a direct invite from a friend, or open the Co Op menu from the main menu bar, browse open public sessions, and filter by domain type to find exactly what you’re farming for. Always check the domain’s level and required elements before joining – if the host is running a level 90 pyro domain and you only have level 40 hydro characters, you’re going to slow the whole team down and waste everyone’s resin. Once you know how to co op domains in Genshin Impact, you can cut your farming time in half compared to running solo, especially if you team up with players who have complementary character builds. I usually add a note to my session description saying what artifact set I’m farming, so other players chasing the same set join instead of people who need a completely different reward.
Unwritten Co Op Domain Etiquette All Players Should Follow
Most of the frustration people face with co op domains comes from players ignoring basic unwritten rules, not from the actual domain difficulty. I’ve seen perfectly good runs fall apart because someone joined and immediately started the run before the host was ready, or brought a completely useless team comp. Follow these simple rules and you’ll be a welcome guest in any session:
- Don’t join a session and immediately start the run without asking – the host might be waiting for a specific character type, or saving resin for a later run, so always check first if everyone is ready to go.
- Bring characters that counter the domain’s elemental weaknesses, not just your favorite level 90 DPS – for example, a Cryo support is far more useful in the Hydro artifact domain than a second Pyro DPS that gets one-shot by the bosses.
- Don’t steal resources from the host’s world without permission – it’s fine to grab a few flowers on the short walk to the domain entrance, but don’t run off to farm their crystal cores or limited regional specialties before the run even starts.
- If you die early in the run, don’t leave immediately – the rest of the team might still be able to clear it, and you’ll still get rewards as long as you’re in the session when the domain is completed.
If you’re hosting, it’s also polite to state what you’re farming for in your session description, so guests don’t join expecting one set and end up wasting resin on another. I also usually mention if I’m okay with players using condensed resin, or if I’m only doing a single run, so no one is caught off guard. These small courtesies take 10 seconds to add, and they eliminate 90% of common co op conflicts.
Common Co Op Domain Mistakes to Avoid for Smoother Runs
Even if you follow all the etiquette rules, there are a few common mistakes that can derail runs even for experienced players. The biggest mistake I see is people bringing a full DPS team without any supports. Even if you have three cracked C6 DPS players, if no one brings a healer or shielder, you’ll all get one-shot by the domain’s mechanics and waste time restarting. Always leave at least one slot on your team for a support character, even if you’re used to running full DPS solo. A well-built Zhongli or Bennett is far more valuable to a co op team than a second DPS.
Another common mistake is forgetting to adjust your party setup before entering the domain. A lot of players keep their open world exploration party equipped, which might have a character for climbing or mining that’s totally useless in combat. Take 10 seconds before you enter the domain to swap to your combat setup, so you don’t end up wasting time swapping mid-fight. Mechanics always come before DPS numbers in co op, because one person ignoring mechanics can make the whole run fail. For example, in the Vindagnyr domain, you need to stay close to the heat sources to avoid freezing to death, but a lot of players run off to attack the boss and end up dying instantly, leaving the rest of the team short-handed.
If you’re a new player, it’s totally fine to say you don’t know the domain mechanics ahead of time. Most veteran players are happy to explain them instead of watching you die repeatedly. I’d much rather take 30 seconds to explain a mechanic to a new player than restart a run three times because they didn’t know what to do.
At the end of the day, learning how to co op domains in Genshin Impact doesn’t have to be complicated, and it’s a great way to make farming feel less grindy while also meeting other players in the community. You don’t need perfect 5-star characters to be a good co op teammate, just a little preparation and respect for the other people in your session. Next time you’re tired of farming artifacts alone, give co op a try – you might even get lucky and roll that perfect 5-star piece you’ve been chasing for months.
