Completing "For Whom the Bell Tolls" in Kingdom Come: Deliverance 2: A Comprehensive Guide
This main quest, unlocked after "Wedding Crashers," requires you to save Hans from execution in Trosky Castle before the bell tolls twelve times. Here's a step-by-step walkthrough:
Initial Tasks:
- Hauling Sacks: You begin by transporting sacks from a wagon to a nearby shed. This is mandatory; simply repeat until complete.

- Assisting the Blacksmith: Next, you must help the blacksmith by crafting a horseshoe. Gather the necessary materials from the forge and return the finished horseshoe to him. Then deliver it to the stables.

- Aiding Fanka the Cook: Retrieve a lockpick from a red pot in the forge area. Speak to Fanka, the cook, and offer your assistance. This grants kitchen access (lockpicking her door is optional but boosts reputation).

Gaining Access to Thomas:
- Interacting with the Chamberlain: In the kitchen, you'll find the ailing Chamberlain. Attempt to persuade him to allow you to brew a Digestive Potion. Success grants access to the surgeon's workshop. Failure requires stealth.

- Crafting the Cure: If you failed to persuade the Chamberlain, acquire food from the kitchen to distract the guard and sneak into the workshop. Otherwise, proceed directly. In the surgeon's workshop, craft a Fever Tonicum (and a Digestive Potion if you convinced the Chamberlain). The necessary ingredients are in the room's chest.

- Treating Thomas: If you helped the Chamberlain, return with the Digestive Potion to gain access to Thomas's room. If sneaking, use the back stairs from the kitchen, distracting the guard at the bottom with a pebble. Give Thomas's sister, Adele, the Fever Tonicum to trigger the quest's conclusion.

Completing these steps before the bell tolls twelve times earns you reputation. However, the quest's outcome remains the same regardless of timing.
