In the main quest "For Whom the Bell Tolls" in *Kingdom Come: Deliverance 2*, Hans needs your assistance once again, this time at Trosky Castle. Your first task is to use alchemy to create a life-saving Fever Tonic. Here’s a detailed guide on how to do it.
Kingdom Come Deliverance 2 Fever Tonic Recipe Location

The recipe for the Fever Tonic can be found in the Surgeon’s Workshop within Trosky’s Castle. You have two options to access this workshop:
- Sneak In: Stealthily enter the workshop to find the recipe.
- Persuade the Chamberlain: If you prefer not to sneak, you can complete the objectives of "For Whom the Bell Tolls" by delivering the horseshoe. Then, return to the forge and speak with Cook Fanka. Offer to help her with her locked chest, and she will lead you to the noble’s kitchen. Inside, you'll find the chamberlain in distress. Engage him in conversation about his health and pass the skill checks to convince him you can help. This grants you access to the Surgeon’s Workshop. If you craft a digestive potion as well and bring it to the chamberlain, he will allow you to meet Thomas.
If your skill checks fail, you'll need to steal some food, exit the kitchen, and head to the opposite side of the courtyard. There, take the stairs to the right which lead to another kitchen. Bribe the guard with the stolen food to clear the area, then sneak upstairs to the Surgeon’s Workshop. Inside, find the surgeon's journal on the bookshelf, read it, and use the station to brew your potions.
How to Brew Fever Tonic

The herbs required for the Fever Tonic are conveniently set up at the surgeon’s station. Here's how to brew it:
- Pour wine into the cauldron.
- Add 3 handfuls of Feverfew.
- Lower the cauldron and boil for 2 turns of the sandglass.
- Grind a handful of Elderberry Leaves with the mortar and pestle.
- Add the ground Elderberry Leaves.
- Add 2 handfuls of Ginger.
- Grab a phial from the bottom left shelf of the station, under the wine.
- Distill the tonic using the Still.
Don't worry if you don't succeed on your first attempt; you have plenty of herbs to work with, and there are more in the chest in the room. Given your prior experience with potion-making, crafting the Fever Tonic should be manageable.
With the Fever Tonic in hand, your next step is to reach Thomas. If you've earned the chamberlain's trust by making a digestive potion, return to him with both potions. Otherwise, use the noble’s kitchen to sneak up to the chapel and find Thomas and his sister, Adele. Speak with Adele to complete the quest.
