Overview
The Last Exploits of Selina’s Gang is a Blood and Wine treasure hunt. It usually starts during Till Death Do You Part, when Geralt kills a group of grave robbers in the catacombs of the Temple Cemetery in Beauclair and reads the letter beside them.
The treasure
The letter points to a hidden cache near Lebioda’s Gate, guarded by a few drowners. Take the ornate key and the sodden letter from it. They lead back to the catacombs and a casket Geralt may already have noticed but could not open. Unlock it to finish the hunt.
