How to Make Fever Tonic in Kingdom Come Deliverance 2

Hans needs your help in "For Whom the Bell Tolls," a crucial quest in *Kingdom Come: Deliverance 2* involving Trosky Castle. This involves a bit of alchemy – specifically, brewing a Fever Tonic. Here's how:

Kingdom Come: Deliverance 2 Fever Tonic: Recipe and Location

The Fever Tonic recipe resides within the Surgeon's Workshop in Trosky Castle. Access is achieved in two ways: sneak in, or use your persuasion skills. To persuade the Chamberlain, convince him you can create a digestive potion to alleviate his stomach troubles. This will grant you access to the workshop.

Alternatively, after delivering the horseshoe during "For Whom the Bell Tolls," speak with Cook Fanka at the forge. Offer to help with her locked chest; she'll lead you to the noble's kitchen. Here, you'll find the ailing Chamberlain. Successfully completing skill checks during your conversation with him will also unlock the Surgeon's Workshop. Crafting a digestive potion alongside the Fever Tonic and returning to the Chamberlain will allow you to meet Thomas.

If your persuasion attempts fail, steal some food, exit the kitchen, and locate another set of stairs leading to a door on your right. This leads to a usable kitchen, guarded by a soldier. Bribe him with the stolen food, then sneak upstairs to the Surgeon's Workshop. You'll find the journal on a bookshelf; read it to obtain the recipe.

How to Brew the Fever Tonic

The necessary herbs are already prepared at 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 using the mortar and pestle.
5. Add the ground Elderberry Leaves.
6. Add 2 handfuls of Ginger.
7. Take a phial from the bottom-left shelf.
8. Distill the tonic using the Still.

Don't worry about failures; you have ample herbs available, including more in the chest.

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