The Armor of Erdrick is found in the town of Rimuldar, which is located on an island to the east of Hauksness. To reach Rimuldar, you will first need to acquire the Magic Key from a hidden shop in the town of Kol (south of Tantegel, requires a bridge). The Magic Key allows you to open locked doors, which are prevalent in Rimuldar. Once in Rimuldar, you'll need to navigate the town and speak to its inhabitants. The Armor of Erdrick is not in a chest; rather, it's given to you by a specific NPC after you've proven yourself or completed a small task. Be prepared for a significant amount of exploration and dialogue. The Armor of Erdrick is the best armor in the game, offering unparalleled defense and even regenerating a small amount of HP per step.
