Overview
Raging Wolf is a Blood and Wine secondary quest that follows Fists of Fury: Toussaint. Once Geralt has beaten every other fighter in the duchy, he may challenge the champion, the Maestro, at Beauclair Port.
The fight
The Maestro has one rule: they fight drunk. After the drinking, it is a normal fistfight, only with the screen swaying as if Geralt had had one too many. A loss is not the end, as Geralt can challenge the Maestro again until he wins. Victory counts as a Proof of Valor for There Can Be Only One.
