Lost King
Lost King Overview
Lost King is a boss-tier creature in ARK: Survival Ascended, fought in a dedicated arena and one of the toughest endgame challenges in the game. It is a carnivore tamed through a special taming method, with Exceptional Kibble as its top-tier food, and brings 400,000 base Health - extraordinarily tanky to the table. Breeding pairs lay fertilized eggs requiring 80°C–90°C incubation, after which juveniles reach adulthood over many real-world days, demanding serious time investment. Once tamed it harvests Hide, Raw Meat, Raw Prime Meat more efficiently than most player tools. Beating it is a milestone unlock, gating tek progression for the tribes that can pull it off.
