If you're looking to end the seemingly endless rivalry between Prochek and Olbram in Kingdom Come: Deliverance 2 during the Battle of the Frogs and Mice side quest, you're in the right place. Here’s how to put an end to their feud once and for all.
How to Start Battle of Frogs and Mice in Kingdom Come Deliverance 2
To kick off the Battle of the Frogs and Mice side quest, you'll first need to complete either the Mice or Frogs quests for Prochek and Olbram. Once you've seen those through, the next quest will unlock. Simply talk to Prochek in Tachov or Olbram in Zhelejov to initiate it. Then, head over to the pasture to begin.
Should You Side With Prochek or Olbram?
Henry finds himself in the middle of the feud yet again, but there's a way to stop it. If you choose to side with one of them, speak to the one you wish to support. For Prochek, go to Tachov and say, “Let’s get those Zhelejovites!” For Olbram, head to Zhelejov and say, “Let’s go and see those Tachovites!”
During their negotiations at the pasture, avoid trying to reconcile them directly as this might trigger the fight prematurely. Instead, if you can pass the dialogue check during the talks, one enemy will flee, making the fight easier. Winning the fight for either side will net you some groschen.
How to Stop the Feud

For a more peaceful resolution, talk to either Prochek or Olbram before heading to the pasture and ask if they want to end the feud. Then, make your way to Troskowitz to speak with Baliff Thrush. Choose the dialogue option, “You’d finally have some peace.”
If you succeed in the dialogue check, you'll be allowed to read the Troskowitz Chronicle in the scribe’s room. If persuasion fails, you can sneak in to read it, but save your game first.
Once in the scribe's room, select the dialogue option, “Fecit, ordinem in regione ope clavi ferrei.”

Next, go to the pasture and find three oak trees aligned. Examine the middle tree to find a nail. You have three options for the nail:
- Leaving it in the middle tree will split the pasture equally between Tachov and Zhelejov.
- Putting the nail in the west tree will give more land to Tachov.
- Putting the nail in the east tree will give more land to Zhelejov.
The choice is yours; it doesn’t significantly impact the outcome. After deciding, speak with Baliff Thrush again, and he’ll agree to end the feud. Then, bring Prochek or Olbram to the pasture to successfully conclude their dispute.
Finally, speak with Baliff Thrush to receive the Master Studies I book.
That’s how you can bring peace to Prochek and Olbram during the Battle of the Frogs and Mice in Kingdom Come: Deliverance 2. For more tips and information on the game, keep exploring The Escapist.
