To progress up each of your Hero's Mastery Tracks, you will need to gain Experience Points (XP) by using them in matches. Each match will net you a flat amount and extra for each star you get:
- Base Amount: 6XP
- Each Star: +10XP
For example, if you got 2-stars in your last match, you will get 26XP in total (6 + (10 x 2)).
Please note, you can skip levels on the tracks by paying Gems.
To amplify the amount of XP earned, players can use additional units of XP Boosters to multiply an equal amount of XP by 3.
For example, if you gained 36 XP in your last match, and you have at least 36 XP Boosters in your Booster pool, that base 36 XP will combine with 36 XP Boosters to ultimately give you 108 XP, tripling what you were supposed to get.
