Witcher Contracts in Military Camp The Witcher 3 Guide
Patrol Gone Missing
You will receive this quest from the Quartermaster Eggebracht in the middle of Nilfgaardian Military Camp (M12,1). A group of soldiers sent on a patrol has gone missing and you must find them. Start the search from examining the camp 500-600 meters to the West from your current position. To find the trail, use your witcher senses.
By following the footprints, you will find a body of dead soldier. Don't get off the road until you find a small cemetery. There will be a Wyvern nearby that you must defeat. After you do it, take the trophy and precious alchemy ingredients. You can also get to the Wyvern by following the smell, but it will be a much longer road.
After you defeat the creature, keep following the footprints. It will lead you to a cave in a small valley. Inside you will find bodies if prisoners of war and a chest with a diagram for Griffin School enhanced silver sword. Now go back to the quest giver. You will receive 50 crowns from him. You can refuse to take the payment. Whether you tell him what you have found in the cave or not, it will impact another quest - Blood Ties.
