A party is for an evening. A clan is the group you belong to.
What a clan gives you
- A shared bank — pooled items with permissions, so a clan can supply its own members.
- A clan boss — Vargath the Wallbreaker, fought by the clan rather than the whole server.
- Group progression — the clan advances as a unit, not just its individual members.
- A place to be — a clan channel separate from global chat.
Joining one
Clans are browsable in game and most accept applications. If you would rather start your own, you can, and recruiting happens in global chat constantly.
Clans sit alongside the other ways to play with people — see how multiplayer works.
