A hard mode reward for the Dawn of the Infinite mega-dungeon has been added.

Put That Thing Back Where It Came From requires players to defeat all bosses in Dawn of the Infinite within a single run and restoring the four time-lost artifacts without any player dying on Mythic difficulty.

This means none of your party members can die during the dungeon.

The reward for the “Immortal” achievement is a cosmetic set: Ensemble: Infinite Acolyte’s Regalia. At this time, we don’t know if the achievement will still be available in Season 3.
