The Ancient Arena is a Bilefen zone event that can be completed in Diablo Immortal to receive various prizes, including Enchanted Dust and a legendary item. Before players can participate in the Ancient Arena event, the campaign missions in Bilefen will need to be completed. Additionally, players will need to level up in order to complete the questline that unlocks the Proving Grounds where the event is located.
Events are special quests that are found in each zone, and some of them are restricted to specific timeframes.

Completing the Ancient Arena event can be difficult, but with a strong party, players may be able to win the PvP challenge.
