The chest and camp are actually a specific location you will reach later in the story. There is an unlocked chest in the camp that contains a full set of St. From the town, travel north and then east from the fork in the road until you reach an abandoned camp on the left, at the following location. To get a full set of plate armor and a powerful sword (worth approximately 10,000 coin) early in the game, travel to the town of Neuhof.
You can actually stand on bushes for a moment before sinking. Navigate up and around to the nest, then use the bushes to jump into the nest. On the edge is a dead horse in a giant nest. Navigate around the cliffs until you can reach the upper edges of the tall cliffside. To find the horse armor, travel into the deep woods east of Ledetchko. It also looks nice aesthetically on the horse. The armor is for the head of the horse, and increases defense when equipped. There is currently only one known location it can be obtained.
Horse armor is extremely rare in the game.
