Blizzard posted the first details on new social features coming to Diablo III on PC. Clans will allow up to 120 players to join players can only join one clan at a time. Communities, on the other hand, have unlimited members and don’t require an invite. Players can also join as many as they’d like.
Both features are currently undergoing testing on the Reaper of Souls Closed Beta and the Patch 2.0.1 public test realm. Blizzard says “We hope that the Clans and Communities make it easier for players to have fun with friends –and make new friends!—while playing Diablo III”.
