This boss can be beaten early on if you are calm and have good reflexes. He doesn't move and is located in the center; just jump on one of the platforms and hit him. When he shoots projectiles all around him, try to dodge them. When he shoots projectiles in a wave pattern you have to jump and move in the direction the projectiles move, with the right timing you will not be hit. If you have the gigantism trait you can also hit him from the ground. Shinobi/Hokage class recommended for high damage and good speed!
