After cutscene you’ll have an option to choose a fair fight or be dishonourable.
I chose the latter, and it unlocked after the cutscene.
Webb Story-related, cannot miss.
The final main quest in the Trosky region takes place at Trosky Castle and is called, “Storm.” In it, Henry and Hans will find themselves back in enemy territory, and after escaping a spot of bother, Henry will have to search the castle for Sigismund’s orders. However, on the way, Henry will meet an old adversary. And it’s you or him!
Once you’ve seen off Istvan’s threat, the ‘Vengenance’ achievement will unlock.
