The combat gyro was acquired after the end of the checkpoint, that is, the level of the library. The door was blocked and we had to fight several armored knights. After the battle, a door opened inside, and we got a new ability to control the combat gyro instead of the blue ball. Controlling the gyro is very simple, just use the ghost hand, or you can hit it a few times and then use the ghost hand, so you can run faster.
