Deer skin

Inside the chest with a hard-to-pick lock in the camp. Can be opened with the nearby Key to Vidlak poacher’s chest.

In a large sack at the edge of the camp.

Sticking out of a box under a makeshift tent.

11 are inside a sack in the Locked dugout. The door has a medium-difficulty lock, and a hostile Smuggler lurks inside.

Found in a medium-difficulty chest in an underground tunnel beneath Burnt Mezholes. You can find the entrance next to the large burned down building east of the map marker.
