If you're aiming for the best ending in *Kingdom Come: Deliverance 2*, completing specific tasks is crucial, and saving Sam is one of them. Understanding where to find Sam is essential for achieving that perfect conclusion.
Rescuing Sam During "Reckoning"
As you near the end of the main quest line, you'll discover that Sam is being held captive at Praguer's Camp. He was taken by Brabant, and your opportunity to rescue him arises during the "Reckoning" quest. However, you can't simply stroll into the camp and set him free. You'll need to choose between stealth or force to infiltrate the camp.
To move freely within the camp without raising suspicion, you'll need a guard's outfit. You can acquire one by either killing a guard and hiding his body to take his clothes, or by searching the numerous chests scattered around the camp. Once you have the outfit equipped, you can explore the camp to locate Sam without being questioned.
When to Rescue Sam
After freeing Sam, it's not yet time to escape with him. He'll inform you about von Aulitz, who is also in the camp. It's advisable to deal with von Aulitz first, then find a horse, and finally return to Sam to help him escape. Sam will be safe waiting a bit longer, and handling the tasks in this order makes everything smoother, especially since you'll need to carry him to the horse.
Von Aulitz is located in the main part of the camp. With your guard outfit, the guards outside his door will allow you entry. Upon finding him, you'll see that von Aulitz is already dying. He requests a dignified death, which you can grant as the most honorable choice. Alternatively, you can choose to kill him brutally or leave him to die slowly. Although these options don't have a massive impact, leaving him to die actually contributes to the best ending.
Your final steps involve retrieving Sam and securing a horse. Sam will still be in the barn where you left him. If a guard questions you about moving him, simply explain that you're handling a body, which will clear any suspicion. Head to the camp gates, exit, and turn right to follow the perimeter.
