The arena is based on one of the town zones, which include Lioneye’s Watch (Act 6), The Bridge Encampment (Act 7), The Sarn Encampment (Act 8), Highgate (Act 4/9), or Oriath Docks (Act 10).

There are a total of 20 waves of enemies to defeat. Interacting with the Strangely Familiar Entity will summon the wave. Each wave increases the difficulty and rewards. Higher waves add additional monster modifiers and increases the level of Delirium. Once the entire wave of enemies is cleared, it will drop all the loot listed. A Stash is available in the zone, allowing you to transfer items between waves. Starting a new wave will destroy all items on the ground.
