Here’s the recipe to get the “Good Ending” for Blood and Wine: • Follow Damien's route. • Complete Beyond Hill and Dale... getting Syanna's Lasso. • During Tesham Mutna, you will have to defeat Dettlaff. • In Pomp and Strange Circumstance, you must investigate with Regis and find out Syanna's motives for doing what she did. Regardless of which ending you choose, the primary mission, Be It Ever So Humble, will be activated after watching it, which works as an epilogue. What you see during this primary mission, which is a sequence, depends on several factors, including whether you have finished the game's story (not the DLC) or not.
