Discover how to obtain Fever Tonic Herbs in KCD2. Enhance your gameplay

The Fever Tonic in Kingdom Come Deliverance 2 is a crucial, though situational, potion. While Henry never suffers from fever himself, this brew is essential for a key story quest. This guide covers everything you need to know about the Fever Tonic: its ingredients, crafting process, and use in the game.

KCD2: How to Get Fever Tonic Herbs

The Fever Tonic is required during the main quest "For Whom the Bell Tolls." To save Hans Capon from execution, you must convince Thomas, the Captain of Trosky, of Hans's noble status. However, Thomas is ill with a fever. Henry offers to find a cure, leading to the need for the Fever Tonic.

Gathering Ingredients

The Fever Tonic requires three ingredients:

These herbs can be found in the wild or purchased from apothecaries. However, during "For Whom the Bell Tolls," purchasing them isn't an option. You must acquire them by lockpicking a chest in the physician's room.

Obtaining Lockpicks


To open the chest, you'll need a lockpick. Here are a couple of ways to get one:

  • Kabat at the Trosky Castle Stables:

    • Purchase: If you have enough Groschen, simply buy a lockpick from Kabat.
    • Retrieve his Rosary: If you're short on funds, Kabat will ask you to retrieve his stolen rosary from Father Nicodemus. You can win it in a dice game or steal it from Nicodemus. Returning the rosary earns you two free lockpicks.
  • The Blacksmith and the Distressed Woman:

    • Craft a horseshoe for the blacksmith.
    • Speak to the distressed woman at the smithy; she'll mention a spice chest she can't open.
    • Convince the blacksmith to help her; he'll give you a lockpick.
  • With a lockpick, unlock the chest in the physician's room to find the Fever Tonic recipe and the necessary ingredients.

    Crafting the Fever Tonic

    Once you have the ingredients and the recipe, follow these steps to craft the Fever Tonic:

  • Base: Pour Wine into the cauldron.
  • Feverfew: Add three Feverfew ingredients.
  • Boil: Boil the Feverfew for two full cycles of the sandglass timer.
  • Elderberry Leaves: Crush a portion of Elderberry Leaves thoroughly and add them to the cauldron.
  • Ginger: Add two Ginger ingredients.
  • Distillation: Select a phial and interact with the distillation flask when prompted.
  • Give the crafted tonic to Thomas to restore his health and advance the quest.

    Fever Tonic Outside the Main Quest

    The Fever Tonic's primary purpose is to cure Sir Thomas during "For Whom the Bell Tolls." It has no other use for Henry; it doesn't provide any health or stat benefits.

    However, if you have extra ingredients or crafted additional tonics, you can sell them to apothecaries or other merchants who deal in herbs and flowers for some extra Groschen.
