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 obtain the recipe and brew the tonic:
Acquiring the Fever Tonic Recipe:
There are two ways 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 depends on skill checks. If you fail, steal some food, give it to a guard near another kitchen entrance, then sneak into the Surgeon's Workshop.
Alternatively, after delivering the horseshoe in "For Whom the Bell Tolls," speak with Cook Fanka. Offering to help with her locked chest grants access to the noble's kitchen and the chamberlain. Successfully persuading him provides access to the workshop.
Once inside the workshop, locate the Physician's journal on the bookshelf. The Fever Tonic recipe is within.
Brewing the Fever Tonic:
The necessary herbs are already on the surgeon's station. Follow these steps:
- 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 with the mortar and pestle.
- Add the ground Elderberry Leaves.
- Add 2 handfuls of Ginger.
- Obtain a phial from the bottom left shelf.
- Distill the tonic using the Still.
Additional herbs are available in the chest if needed.
Completing the Quest:
After crafting the Fever Tonic (and optionally, a digestive potion), deliver it to Thomas. If you gained the chamberlain's trust, return to him with both potions. Otherwise, use the kitchen to reach Thomas and his sister, Adele, in the chapel to conclude the quest.
