1. For the final boss of the last sword, just walk and face to face and bounce back. The boss will hide from you, so don't flash and face to attack.
2. The boss will teleport away a lot when reading the command. Anyway, the farther away it is, the harder it is to fight.
3. If you want to be quick, you can hit the second stage with two swords within a few dozen seconds of meeting. In the second stage, the boss will start to wear Invincible on him. Just hide for a while. You can still walk to face him. When the boss is gone, walk up to him and end the battle with one sword.
