How to Craft Fever Tonic in Kingdom Come: Deliverance 2

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 is to harness the power of alchemy to save someone by crafting 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 gain access to this workshop. The first is to sneak in discreetly. The second involves using persuasive dialogue to convince the chamberlain that you can create a digestive potion to alleviate his stomach issues, which will grant you entry to the workshop.

If sneaking isn't your style, you can progress through the "For Whom the Bell Tolls" quest by delivering the horseshoe. After completing this task, 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. Upon entering, you'll notice the chamberlain suffering from pain. Engage him in conversation about his health and attempt to pass the skill checks to convince him of your ability to help. Successfully doing so will grant you 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 resort to stealth. Steal some food, exit the kitchen, and head to the opposite side of the courtyard. Ascend the stairs to the right, which lead to another kitchen you're permitted to use, though a guard is present. Offer him the stolen food, and he will leave. From there, you can sneak upstairs to the Surgeon's Workshop, locate the physician's journal on the bookshelf, and use the station in the room to brew your potions.

How to Brew Fever Tonic

The herbs required for the Fever Tonic are conveniently arranged at the surgeon's station. Open your book to the page on Fever Tonicum and follow these steps:

• 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 using the mortar and pestle.
• Add the ground Elderberry Leaves to the mixture.
• Add 2 handfuls of Ginger.
• Retrieve a phial from the bottom left shelf of the station, located under the wine.
• Distill the tonic using the Still.

Don't worry if you don't succeed on your first attempt; you have ample herbs at your disposal, 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 reach 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 sneak up to the chapel where you'll find Thomas and his sister, Adele. Converse with Adele to complete the quest.
