When do You Need the Fever Tonic Herbs & Potion in Kingdom Come Deliverance 2

During the main quest For Whom the Bell Tolls in Kingdom Come Deliverance 2, you’ll need to obtain a Fever Tonic for the first time. This quest goal is to save Hans Capon, who is set to be hanged. The only person who can stop the execution and prove Hans’ noble status is Thomas, the Captain of Trosky. However, Thomas is sick, and his sister cannot cure him.

This is where Henry steps in. He offers to visit the physician’s room to find a solution, which leads to the need for the Fever Tonic.

How to Get Ingredients for the Fever Tonic in Kingdom Come Deliverance 2

To craft the Fever Tonic, you will need three key ingredients:

• Feverfew
• Elderberry Leaves
• Ginger

These herbs can be found in the wild or purchased from apothecary traders scattered throughout the game world. However, that is not an option while saving Sir Thomas during the For Whom the Bell Tolls quest. So you will need to lockpick a chest in the physician’s room, which contains all the necessary components for the potion.

How to Get Lockpicks

To open the chest, you will need a lockpick. Here is how to get one:

1. Head to the Stables of Trosky Castle and speak with Kabat, a local trader.
2. If you have enough Groschen, you can simply buy a lockpick from him.
3. If you are short on funds, Kabat will ask you to retrieve his stolen rosary from Father Nicodemus. You can get the rosary back by either winning it in a game of dice or looting it from Father Nicodemus’ purse.
4. Once you return the rosary to Kabat, he will reward you with a couple of free lockpicks.

Another way to get a lockpick:

1. Talk to the blacksmith and craft a horseshoe.
2. After giving the horseshoe to Kabat, find the distressed woman at the smithy.
3. Talk to her, and she will complain about a spice chest that she cannot open.
4. Talk to the blacksmith and convince him that you will help her with the chest, and he’ll give you a lockpick.

With the lockpicks in hand, you can now unlock the chest in the physician’s room. Inside, you will find the Fever Tonic recipe needed to brew the potion. Once crafted, give the tonic to Thomas to restore his health and progress the quest.

How to Craft the Fever Tonic for Sir Thomas in Kingdom Come Deliverance 2

After following all of these steps mentioned here. you will be able to brew the Fever Tonic concoction:

• Step 1: Start by pouring Wine into the cauldron as the base for your potion.
• Step 2: Add three Feverfew ingredients to the mixture.
• Step 3: Allow the Feverfew to boil for two full cycles of the sandglass timer.
• Step 4: Take a portion of Elderberry Leaves, crush them thoroughly, and then mix them into the cauldron.
• Step 5: Add two Ginger ingredients to the mixture in the cauldron.
• Step 6: Begin the distillation process by selecting a phial and interacting with the distillation flask when the prompt appears.

What to do with Fever Tonic Outside Main Quest in Kingdom Come Deliverance 2

The Fever Tonic is primarily a quest-specific potion that Henry is required to craft during the For Whom the Bell Tolls main quest. Its sole purpose is to cure Sir Thomas’ fever, allowing him to intervene and save Hans Capon from execution.

However, once the quest is complete, the Fever Tonic has no practical use for Henry himself. It does not provide any benefits to his health or stats, making it essentially useless outside of the quest.

That said, the potion is not entirely without value. If you have gathered extra ingredients or crafted additional tonics, you can sell them to apothecary traders or other merchants who deal in herbs and flowers. Selling Fever Tonics can be a decent way to earn some extra Groschen, especially if you are looking to pad your wallet.
