Yeah, remembering what he does is the best thing to do. First, just stay under Dracula as he summons a rain of blood. Once he is on the ground, he summons bats at you, just duck near him. After, he usually turns into a wolf. If he jumps back he will come straight at you, if he backflips, he will jump and just stay under him. Then, he does the bat thing again. This time he summons a flame pillar under. Then he uses like these cut attacks, just run and once its over try to stay in the middle of the last part of the attacks.
In the end, he turns into a series of small bats and there is this red thing you can destroy and then able to attack the small bats.
