Locked Boosters
These can be obtained once a day by collecting 10 key fragments. You earn fragments by playing League Matches. A loss gives 1 and a win gives 3.
Time Boosters
You can get these by winning League Matches. They unlock by either waiting the amount of time listed, or using gems. You can only have three Time Boosters in your possession at any one time
