Light Castellan Sieghart

The boss of Castellan's Chamber. Essentially a floating armor, he cannot be knocked down, and combines attacks from previous bosses. He has a super armor slash which knocks down, a light-type blow-back that hits around him, and a beam attack that is similar to Evil Eye's Left Eye. He will sometimes float up into the air and cast many lightning bolts, and may use several more attacks before coming back down again. He is resistant to light element attacks.
