Main quests in *Kingdom Come: Deliverance 2* can be quite stressful, particularly when they involve sneaking through unfamiliar territories under time constraints. One such challenging quest is "For Whom the Bell Tolls." Here's a detailed guide on how to successfully navigate this quest and save Hans before the clock runs out.
Kingdom Come: Deliverance 2 - For Whom the Bell Tolls Walkthrough
The quest "For Whom the Bell Tolls" begins immediately after completing "Wedding Crashers." Now imprisoned in Trosky, Hans faces execution once the bell tolls 12 times. Fortunately, Henry is assigned to work as a laborer around the castle instead of staying in prison, giving him a chance to rescue Hans.
Hauling Sacks

Your first task is to haul sacks to a shed, which is a mandatory part of the quest. Start by taking a sack from the wagon and carrying it to the shed next to the fenced area. Drop the sack inside the shed and repeat this process until the objective is complete.
Help the Blacksmith

Next, you're tasked with assisting the blacksmith, who reluctantly asks you to craft a horseshoe. Head through the archway opposite the blacksmith to reach the forge area. Gather the necessary materials from the forge, craft the horseshoe, and return it to the blacksmith for his approval. Then, proceed along the path you used for hauling sacks to the stables and deliver the horseshoe there.
Help Fanka the Cook

After delivering the horseshoe, it's time to assist Hans. Return to the forge and retrieve a lockpick from the red pot on the shelves. Then, engage with the woman nearby, Fanka, who is a cook in the noble's kitchen. Offering your help to Fanka grants you access to the kitchen. Follow her there, and consider lockpicking to boost your reputation and secure future food access.
Speak with the Chamberlain

Upon entering the kitchen, you'll notice the chamberlain suffering from pain. Engage with him and try to persuade him to allow you to brew a Digestive Potion. Success grants you access to the surgeon's workshop; otherwise, you'll need to sneak in.
Make Fever Tonicum

If you couldn't persuade the chamberlain, grab some food from the kitchen to distract the guard and sneak into the workshop. Otherwise, proceed with the granted access. Navigate to the stairs opposite the forge, enter the common kitchen, and deal with the guard by offering him the food. Then, ascend the stairs to reach the surgeon's workshop, where you'll find enough ingredients to craft both the Fever Tonicum and, if needed, the Digestive Potion.
Cure Thomas

If you're aiding the chamberlain, return to him with the Digestive Potion to secure permission to help Thomas. If sneaking, you'll need to navigate another route. Head back to the noble's kitchen and take the stairs up, avoiding guards by staying crouched. When you encounter a guard at the base of a staircase leading to Thomas' room, throw a pebble to distract him and sneak past. Proceed to Thomas' room, where you'll find him in bed with his sister Adele. Hand over the Fever Tonicum to Adele, triggering the quest's concluding cutscene.
That's how to complete "For Whom the Bell Tolls" in *Kingdom Come: Deliverance 2*. Helping Thomas before the 12 bells toll enhances your reputation, but the quest's outcome remains consistent regardless.
