Black Desert Online EU/NA - Arena of Arsha
As usual, today after the regular maintenance of Black Desert Online EU/NA, a new kind of arena which is called "Arena of Arsha" was released. This arena allows you to be the operator to hold pvp matchs of a special battle arena, beside choosing your own teams.
You have to be a Guild Master or Guild Officer so you can reserve the Arena of Arsha by setting a specific date to claim the right to run the Arena of Arsha, and when the reserved date comes you'll be able to invite other players to participate in Team Matches or Team Survivals.
Also the Arena of Arsha reservation requires guild funds (10m silvers), but it's not required for the spectating or participating players, which means the invitation of the operator is the only thing required for them, regardless of their affiliated guild.
The difference between Arena of Arsha and Red Battlefield is that you can form your teams, set the match time, number of rounds, and regulations of the matches.
