Why do I sometimes use e to shield my teammates when I play League of Legends clockwork, and then my teammates rush up and I make a big move, but my feet are empty?

The reason is that your ball, no matter which skill, has a distance limit from yourself. After exceeding the distance, it will automatically come back to you. In your case, your teammates must have rushed out of your limit distance and then came back to you. That's it. You must have stepped on it.

PS: When you play skills, the circle of the limit distance will be displayed. Pay attention. After the ball is released, there will be a small arrow on the spring, and the arrow of the ball's distance change will change color. Ask questions and ask for adoption.
