This boss took some hours. Very hard final boss with 4 forms. First form was no damage but fucked up alot on second form. Often I can beat the second form with no damage or using only one healing item. Third form I just finally learned that I needed to be running toward him and dodge under his jump to counter him. Fourth form is basically the same as the third with an added lightning attack. Big issue is when you are locked on you cant see the edges and can easily die from pit falls if you have less than 1/2 health. The other issue is the camera losing lock on at random times which can get you killed. These strategies were not my own and I started digging into my back up items. Definately not a clean run but my first time beating these bosses. I think I grinded my attack level with the dancing mask to 20 before I decided it was good enough. My main issue was not knowing how to dodge and counter the final two forms for a while. Theres no real time to practice since you have to keep redoing the first 2 forms each time.
