Hey there, been playing d2 with my girlfriend (PS4) And she just bought the D2 The Witch Queen Dungeon Key for 2000 silver in the Eververse store however, she has not been given the "A Single Thread" quest from Hawthorne. We are not game-sharing d2 or any of the content, so I am unsure as to why the quest hasn't appeared. Does she need to progress in the legacy: 'The Derelict Leviathain' quest first?
Hello. Yes, she will need to unlock the Leviathan by playing that quest first before gaining access to the Dungeon.
