In the immersive world of Kingdom Come: Deliverance 2, Hans calls upon you once more in the main quest "For Whom the Bell Tolls," centered around Trosky Castle. Your first task is to harness the art of alchemy to craft Fever Tonic, a crucial potion that will aid in your mission. Here's a detailed guide on how to find the recipe and brew the Fever Tonic.

Kingdom Come Deliverance 2 Fever Tonic Recipe Location

The recipe for Fever Tonic can be found within the Surgeon's Workshop at Trosky Castle. You have two options to gain access to this area. The first involves stealthily sneaking into the workshop. Alternatively, you can use your persuasive skills to gain entry by speaking with the chamberlain.

If you choose not to sneak, you'll need to progress through the "For Whom the Bell Tolls" quest by delivering the horseshoe. After this, return to the forge and engage 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 notice the chamberlain in discomfort. Strike up a conversation about his health and attempt to pass skill checks to convince him of your ability to help. Success here will grant you access to the Surgeon's Workshop. Additionally, if you craft both a digestive potion and the Fever Tonic, the chamberlain will introduce you to Thomas.

If your skill checks fail, you'll need to resort to stealth. Steal some food and exit the kitchen, then head across the courtyard to another set of stairs leading to a door on your right. This door opens into a kitchen you're permitted to enter, but a guard is present. Offer him the stolen food, and he will leave, allowing you to sneak upstairs to the Surgeon's Workshop. Locate the physician's journal on the bookshelf, read it, and use the station in the room to brew your potions.

How to Brew Fever Tonic

Brewing the Fever Tonic is straightforward once you're at the surgeon's station, where the necessary herbs are already set out. Follow these steps to create 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.

Don't worry if you don't succeed on your first attempt; there are ample herbs available, and more can be found in the chest within the room. Given your prior experience with potion-making, crafting the Fever Tonic should be manageable.

Once you've successfully brewed the Fever Tonic, your next step is to find Thomas. If you've earned the chamberlain's trust by crafting a digestive potion, return to him with both potions. Otherwise, use the noble's kitchen to stealthily reach the chapel where Thomas and his sister, Adele, are located. Speak with Adele to complete the quest.

This comprehensive guide ensures you're well-equipped to tackle the alchemy challenge and progress in "For Whom the Bell Tolls" within Kingdom Come: Deliverance 2.
