Cloud Sea King Ken

Cloud Sea King Ken is one of the Superbosses in Xenoblade Chronicles 2. It is a Unique Monster and a member of the Squood family; it can be found at level 110 at Genbu Drifts, near the Central Ether Boulder, in the Kingdom of Tantal during foggy weather. It is the only source of Moon Matter Chips in the game. After its defeat, its gravestone can be found on the southwest side of the lake, a modest distance inland from the shore. It can be fought at level 140 during the Challenge Battle Cloud King's Revenge, which is available as downloadable content from the Challenge Battle Mode Pack of the Expansion Pass. Defeating Cloud Sea King Ken for the first time is necessary for the Cloud King's Revenge Challenge Battle to become available.
