This guide details how to complete the "For Whom the Bell Tolls" quest in Kingdom Come: Deliverance 2. This main quest, following "Wedding Crashers," involves rescuing Hans from execution in Trosky Castle.

Key Steps:

1. Hauling Sacks: Begin by transporting sacks from a wagon to a nearby shed. This is a mandatory task.

2. Assisting the Blacksmith: Next, help the blacksmith by crafting a horseshoe using materials found at the forge. Deliver the finished horseshoe to the stables.

3. Aiding Fanka the Cook: Retrieve a lockpick from a red pot in the forge area. Use it (or simply speak to her) to gain access to the noble's kitchen by assisting Fanka. Helping her improves your reputation.

4. Interacting with the Chamberlain: Speak to the ailing chamberlain in the kitchen. Attempting to persuade him to let you brew a Digestive Potion might grant you access to the surgeon's workshop; otherwise, stealth is required.

5. Crafting the Fever Tonicum: If you didn't convince the chamberlain, discreetly obtain food from the kitchen to distract a guard and access the workshop. In either case, proceed to the surgeon's workshop (located upstairs) and craft a Fever Tonicum (and a Digestive Potion if you persuaded the chamberlain).

6. Treating Thomas: Deliver the Digestive Potion to the chamberlain (if applicable) to gain access to Thomas's room. Alternatively, if sneaking, navigate carefully through the castle, distracting guards as needed, to reach Thomas. Administer the Fever Tonicum to Thomas to complete the quest.

Successfully treating Thomas before the bell tolls twelve times increases your reputation. However, a successful outcome is guaranteed regardless of timing.
