A Cross-World Linkshell (CWLS) is an in-game chat channel in FFXIV that allows you to communicate with players who are on different servers (Worlds). While standard Linkshells restrict chat to players on your specific home server, a CWLS expands this, letting you stay connected with friends across your data center.
You can join up to eight Cross-World Linkshells.
How to Join a Cross-World Linkshell
You cannot browse and join a CWLS directly from an in-game menu on your own; you must be invited by a master or leader of that specific linkshell.
Here are the primary ways to get an invitation:
Use the Community Finder: The easiest way to find a group is online via the official FFXIV Community Finder. You can filter groups by your data center, language, and interests. Once you find one you like, you can leave a comment or contact the recruiter in-game.
In-Game Shouting: If you are looking for a specific type of community, like a "Hunt Train" or "Raids" tracking group, you can type /shout in highly populated city-states or during community events asking for an invite.
If you are already friends with someone in a CWLS, they can right-click your character or name in their friends list and select "Invite to Cross-World Linkshell".
How to accept the invite
When someone sends you an invitation, a notification will pop up. To accept it:
1) Open your Social menu from the bottom right corner (or press O on your keyboard).
2) Select Cross-World Linkshell.
3) Click on the pending linkshell name and select Accept Invite
( If you are playing on the Free Trial, you are fully allowed to join an existing CWLS if someone invites you, but you cannot create your own.)
