More details about saving:

The entire story campaign and both DLCs have been completed, all witcher orders and almost all side quests have been completed (except for witcher equipment), all questions on the map have been opened, except for Toussaint (about half there).

Equipment: full set of the Manticore school, Arondite and the steel sword of the Toussaint knight.

Level 54 and 31 thousand crowns.

At the time of the last save, New Game+ was started (difficulty "to death"), but due to the large number of saves, you can roll back to the beginning of Toussaint.
