Beyond the main story bosses, Core Keeper has several optional boss encounters that provide unique loot and challenges. These include the Caveling Matron, found in the Clay Caves, and the Morpha, found in the Sunken Sea. Each optional boss has its own mechanics and requires specific strategies. Defeating them often rewards you with powerful legendary items or unique crafting materials that can significantly boost your character's power. Always prepare thoroughly before engaging these formidable foes.
