Gyro Man Can't Use Energy Boost Posted by Yoshi2019 on December 13th, 2018 at 7:29pm Viewed 78 Times
My Gyro Man is able to both learn and use Energy Boost (as seen in the image below). Perhaps you tried to use it while Gyro Man was at full health or something? Can you post a screenshot of Energy Boost failing? Thanks.
