Kingdom Come Deliverance 2: Making Fever Tonic a Home Remedy

In Kingdom Come: Deliverance 2, Hans's main quest, "For Whom the Bell Tolls," requires crafting a Fever Tonic to aid Thomas. This guide details how to obtain the recipe and brew the tonic.

Acquiring the Fever Tonic Recipe:

There are two approaches to accessing the Surgeon's Workshop in Trosky Castle, where the recipe resides:

• Stealth: Discreetly infiltrate the workshop.
• Diplomacy: Convince the ailing Chamberlain you can create a digestive potion. Successful skill checks will grant you access to the workshop. If you fail, steal food, give it to a guard near another kitchen entrance, and then sneak into the workshop.

After gaining access, locate the Physician's Journal on a bookshelf.

Brewing the Fever Tonic:

The necessary ingredients are already present on the surgeon's station. Follow these steps:

1. Pour wine into the cauldron.
2. Add 3 handfuls of Feverfew.
3. Lower the heat and boil for 2 turns of the sandglass.
4. Grind a handful of Elderberry Leaves.
5. Add the ground Elderberry Leaves.
6. Add 2 handfuls of Ginger.
7. Obtain a phial from the bottom-left shelf.
8. Distill the tonic using the Still. Multiple attempts may be necessary.

Completing the Quest:

Once the Fever Tonic is brewed, locate Thomas. If you gained the Chamberlain's trust by providing a digestive potion, return with both potions. Otherwise, use the kitchen to reach the chapel and find Thomas and his sister, Adele. Speak with Adele to conclude the quest.
