The Aetherial Witch
An Act 4 side quest offered by Captain Reave in Fort Ikon after Betrayal at Fort Ikon. Speak with Anasteria in Fort Ikon Prison, then choose whether to spare her and ally with the Outcast or kill her and make the faction hostile.
Despite the title, this is a Base Game Act 4 faction choice, not an Ashes of Malmouth Coven quest. The prison is northwest of the Fort Ikon Rift and opens after accepting. Anasteria's dialogue determines Outcast allegiance, vendor and augment access, follow-up quests, and access to her hostile dungeon and unique MIs.
