Throughout rescuing his horse from poachers, Henry brings Vostatek home to a disgruntled son and wife.

Later in KCD2's first act, Henry arrives at Olga and Agnes's wedding at Semine. There, Henry once again bumps into Vostatek, who pleads with Henry to keep an eye on him so he doesn't get drunk during the wedding and upset his wife. Henry must find Vostatek throughout the wedding party and keep the drink out of his hands if he agrees.

Vostatek's First Location During The Wedding

Get The First Drink Away From Vostatek

After you've agreed to help Vostatek, talk with other NPCs around the wedding and do some other tasks. Eventually, he will move from his first point, and you'll have to interact with him to continue his quest. This is an easy quest to complete, as Henry won't need any KCD2's skills to keep Vostatek out of trouble.

Vostatek can be found drinking for the first time in the stables, where you can also enjoy some of Kingdom Come: Deliverance 2's combat in the arena that is set up. He will be watching one of the fights that is taking place. Talk to him and choose to take the drink off him, then carry on with more tasks around Semine until he moves.

To check whether Vostatek has moved, look at the task in your journal. If it says that he's okay, then he hasn't moved yet, but if it says you should check on him, he'll be in a new location.

Vostatek's Second Location During The Wedding

Stop Vostatek From Drinking, Again

Once he has moved away from the fighting arena, you'll have to find him again and take his drink off him. Luckily, he doesn't go that far.

To keep Vostatek from getting drunk, you can find him at the very back of the barn - the opposite end of the fighting arena.

Vostatek will be hanging around a barrel underneath the stairs. Talk to him once again and take away his cup.

Vostatek's Third Location During The Wedding

Take Vostatek's Drink Away The Final Time

After two unsuccessful attempts to get drunk, the Gameskeeper gets a bit more tricky when it comes to hiding his booze. Fortunately, Henry won't have to keep chasing around after him once he takes his drink away the third time.

To find Vostatek for the third time, head to the pond outside the walls of Semine. It's the same spot where Henry talks to Myshka in private and also where he finds the sword for Radovan after it goes missing. Take Vostatek's drink away and carry on with the wedding.

Vostatek's Fourth Location During The Wedding

Make Sure Vostatek Got Through The Wedding

By this point, you should have completed most of the wedding activities, and the bride and groom should be married. Before you go and congratulate the happy couple, you must find Vostatek one final time to ensure he's survived the evening without getting drunk.

Vostatek can be found in the courtyard where you first found him, again talking to his wife. This time, he'll be just outside the kitchen door. Talk to him, and he will thank you for not letting him get drunk and ask you to stop by his house in the future.

You will have to wait a while to see the Gameskeeper again, as the events directly after the wedding in Semine bring some big story developments for Kingdom Come: Deliverance 2, and you'll be forced to move away from the Trosky region for a while. When you eventually return to Trosky, make sure to return to Vostatek's house to see what else he has in store for you.
