In Kingdom Come: Deliverance 2, Hans's main quest, "For Whom the Bell Tolls," requires crafting a Fever Tonic to help someone at Trosky Castle. Here's how to acquire the recipe and brew the tonic:
Obtaining the Fever Tonic Recipe:
There are two methods to access the Surgeon's Workshop in Trosky Castle, where the recipe resides:
-
Stealth: Sneak into the workshop.
-
Diplomacy: Convince the chamberlain you can create a digestive potion for his stomach ailment. Success requires passing skill checks. Failing these checks necessitates stealing food, bribing a guard with the stolen food to gain access to the kitchen, and then sneaking to the workshop.
If you choose the diplomatic route and successfully convince the chamberlain, he'll grant you access to the Surgeon's Workshop. Inside, you'll find the Physician's Journal.
Brewing the Fever Tonic:
The necessary herbs are already present on the surgeon's station. Follow these steps, using the Fever Tonicum recipe from the journal:
- Pour wine into the cauldron.
- Add 3 handfuls of Feverfew.
- Lower the heat and boil for 2 turns of the sandglass.
- Grind a handful of Elderberry Leaves using the mortar and pestle.
- Add the ground Elderberry Leaves.
- Add 2 handfuls of Ginger.
- Take a phial from the bottom-left shelf.
- Distill the tonic using the Still.
Additional herbs are available in a chest within the room if needed.
Completing the Quest:
After brewing the Fever Tonic, deliver it to Thomas. If you have the chamberlain's trust (by making the digestive potion), return to him 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.
