Crafting Fever Tonic in Kingdom Come Deliverance 2: A Guide

In the main quest "For Whom the Bell Tolls" in *Kingdom Come: Deliverance 2*, Hans requires your assistance once more, this time at Trosky Castle. Your first task involves using alchemy to save someone by brewing Fever Tonic. Here's a detailed guide on how to locate the recipe and brew the Fever Tonic.

Kingdom Come: Deliverance 2 Fever Tonic Recipe Location

The recipe for Fever Tonic can be found in the Surgeon's Workshop within Trosky's Castle. You have two options to access this workshop:

1. Sneak into the workshop: This method requires stealth and careful movement to avoid detection.
2. Convince the chamberlain: By engaging with the chamberlain, you can offer to make him a digestive potion to alleviate his stomach issues. Successfully passing the skill checks during this conversation will grant you access to the workshop.

If you prefer not to sneak, proceed with the quest by delivering the horseshoe as part of "For Whom the Bell Tolls". After that, return to the forge and speak with Cook Fanka. Offering to help her with her locked chest will lead you to the noble's kitchen. Upon entering the kitchen, you'll find the chamberlain in pain. Engage with him about his health and attempt to pass the skill checks to gain access to the Surgeon's Workshop. If you also craft a digestive potion alongside the Fever Tonic and return 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 other side of the courtyard. There, you'll find another set of stairs leading to a door on your right, which leads to a kitchen you're allowed to use, albeit guarded. Offer the stolen food to the guard to make him leave, then sneak upstairs to the Surgeon's Workshop. Inside, locate the physician'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 already set up at the surgeon's station. Follow these steps to brew the potion:

1. Pour wine into the cauldron.
2. Add 3 handfuls of Feverfew.
3. Lower the cauldron and boil for 2 turns of the sandglass.
4. Grind a handful of Elderberry Leaves with the mortar and pestle.
5. Add the ground Elderberry Leaves.
6. Add 2 handfuls of Ginger.
7. Grab a phial from the bottom left shelf of the station, under the wine.
8. Distill the tonic using the Still.

If you don't succeed on your first attempt, don't worry. You have ample 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.

Once you've brewed the Fever Tonic, you need to reach Thomas. If you've earned the chamberlain's trust by providing him with a digestive potion, return to him with both potions. Otherwise, use the noble's kitchen to sneak up to the chapel where you'll find Thomas and his sister, Adele. Speak with Adele to complete the quest.
