“Mythic+ Season 2 introduces increased item levels for rewards and new mounts, along with a new dungeon affix: Tormented Servants of the Jailer,” Blizzard says. “These servants can be found throughout the dungeon and grant powerful boons when defeated. In addition, if a servant is not dealt with, they empower the final boss. Season 2 also brings with it Torghast, Tower of the Damned Layer 10, and the opening of Tazavesh, the Veiled Market on Mythic difficulty.”
