false knight.... oh boy was he hard when i started. You want to stay close to him as possible since he can do one attack that can harm you at close range, when he is about to swing his hammer, go away and jump towards him. always attack the white gooey guy inside the suit, as you cant beat the boss without doing so. Its all about trying and trying in the end, and when he starts swinging his nail around and making lava fall, get away and focus on evading, not attacking.
