The access conditions for Lostbelt 7 are simple. Players will need to complete Tunguska Prologue/Epilogue to access the new chapter. No other quests need to be completed to access Lostbelt 7. However, this new chapter contains spoilers for Chapter 6.5, Traum: Life and Death of a Fantasy. For this reason, Lasengle strongly encouraged players to complete the previous chapter in order to avoid said spoilers.
Earlier in December 2022, Lasengle revealed a teaser trailer for Lostbelt 7. You can watch it here.
In November 2022, Lasengle confirmed Daybit as the Crypter for Lostbelt 7. We know that he has a Grand Servant, but their identity hasn’t been revealed yet.
