How to Craft Fever Tonic in KCD 2: A Step-by-Step Guide

In the main quest "For Whom the Bell Tolls" in *Kingdom Come: Deliverance 2*, Hans requires your assistance once again, this time at Trosky Castle. Your initial task is to harness alchemy to save someone by brewing Fever Tonic. Here's how you can achieve this:

The recipe for Fever Tonic can be found within the Surgeon's Workshop at Trosky's Castle. There are two approaches to access this workshop:

• Sneaking In: You can attempt to stealthily enter the workshop if you prefer a more covert approach.
• Persuasion: Alternatively, engage with the chamberlain in the kitchen, who is suffering from stomach issues. By offering to make him a digestive potion, you can persuade him to grant you access to the Surgeon's Workshop.

If you opt not to sneak in, progress through the "For Whom the Bell Tolls" quest by delivering the horseshoe. After, revisit the forge and speak with Cook Fanka. Offer to help her with her locked chest, and she will guide you to the noble's kitchen. Upon entering, you'll find the chamberlain in distress. Engage him in conversation about his health and use your skills to convince him of your ability to help, which will open the way to the Surgeon's Workshop. Bringing him a digestive potion along with the fever tonic will further earn his trust, allowing you to meet Thomas.

Should your skill checks fail, you'll need to resort to stealing some food. Exit the kitchen and cross the courtyard to another set of stairs leading to a door on your right. This path takes you to a different kitchen, but be wary of the guard present. Offer him the stolen food to vacate the area, then sneak upstairs to the Surgeon's Workshop. Locate the surgeon's journal on the bookshelf, read it, and use the station in the room to craft your potions.

How to Brew Fever Tonic

The herbs necessary for the Fever Tonic are conveniently set up on 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 using the mortar and pestle.
5. Add the ground Elderberry Leaves to the mixture.
6. Add 2 handfuls of Ginger.
7. Retrieve a phial from the bottom left shelf of the station, beneath the wine.
8. Distill the tonic using the Still.

If you don't succeed on your first attempt, don't fret. There are ample herbs available, with more stored in the chest within the room. Given your prior experience in brewing potions, crafting the Fever Tonic should be straightforward.

Once you have the Fever Tonic, your next step is to reach Thomas. If you've earned the chamberlain's trust with the digestive potion, return to him with both potions. Otherwise, use the noble's kitchen to sneak to the chapel where you'll find Thomas and his sister, Adele. Converse with Adele to complete the quest.
