Thunder Manifestation in Genshin Impact can be said as the electronic version of Oceanid Boss. It is made entirely of electricity, which makes it completely immune to electrical attack. While it is quite difficult to defeat Thunder Manifestation in Genshin Impact, just unlocking the boss is difficult in itself too.
Thunder Manifestation is located on one of the two new islands of Inazuma. His hiding place is the center of the Seirai Island and is located in Amakumo Peak.

Players must complete a series of tasks to enter the boss fight. The lightning barrier around the top of the mountain, called the balethunder effect, keeps players away from the electronic boss. Players must complete all parts of the Seirai Stormchasers mission chain (4) and obtain the Inazuma: The Islands of Thunder and Eternity – Series II Achievement Seirai Stormchasers.
