Description on the official Path of Exile website ^[1]

The Delve league and Hardcore Delve league were challenge leagues.^[1]^[2] They launched on August 31, 2018 and ended December 3, 2018.

The league adds an infinitely scaling dungeon called the Azurite Mine. You can find deposits of Voltaxic Sulphite in a zone, which Niko the Mad will collect to power his Crawler, which is used to guide the player in the Delve through the deadly darkness. Each Delve can contain items or Azurite, which can be used to upgrade your equipment and items to help in future Delves. Delves can contain special biomes, boss encounters, and socketable currency items which influence the types of mods created on an item.

All characters and stashes were moved to the Standard league and Hardcore league respectively when the leagues end. Characters that die in the Hardcore Delve league are immediately moved to the permanent Standard league.
