Each Kick can only conduct a total of 3 mints. However, it is not guaranteed that you're able to do 3 mints with you Kick as the mint might also fail, which can result in your Kick being burned. There is a 50% chance that your mint is successful, but also a 50% chance that your mint fails. When a mint fails one of the two Kicks being used for the mint is randomly Burned. Once you Kick is burned, there is no way to get it back and it is lost forever.
