Genshin Impact co-op: get useful help without wasting resin

Name the exact boss, domain or material before opening your world. A specific request gets a useful teammate faster than a general call for help.

Check the domain's enemy lineup and elemental recommendations before matching. Bring a support or healer when another player already covers the main damage role.

Agree on how many runs you are doing before spending Original Resin. This keeps short farming sessions focused and prevents players leaving mid-run.

For overworld materials, tell the host what you intend to collect and wait for permission. Resources belong to the host's world and respectful farming builds trust.
