Each hero has their own Mastery.
You can gain Hero Mastery experience based on your rank after each match ends.
Mastery can go up to Lv. 10.
30 – My Rank + Random 1~20 = Hero Mastery Experience acquired
※ If above calculation is 0 or lower, you will not gain Hero Mastery EXP.
e.g.) 30 - 37(My Rank) + 2(Random) = -5 (Gained 0 Hero Mastery EXP)
e.g.) 30 - 5(My Rank) + 8(Random) = 33 (Gained 33 Hero Mastery EXP)
In addition, you can acquire Skill Stones each time your hero’s Mastery increases. Use Skill Stones to enhance your hero’s skill of choice.
