Chaos Dungeon
Run Agony Wave for seasonal rewards
Agony Wave turns Chaos Dungeon keys into a scalable seasonal challenge with reward choices and access to seasonal Essences.
Agony Wave in Saluto, unlocked after Act 13 and the Unidentified Phenomenon quest.
Repeatable with Agony Keys. Agony Wave supports up to 100 waves, but do not assume you need to reach the cap to receive a reward; the run ends on failure or completion and chest access follows the battle.
Stop when the run ends or when your build can no longer continue; claim the best chest available with your Shards before leaving the reward area.
