How do I promote hero’s
You need to farm soulstones for your hero, in order to promote it to higher grade.
- It will take 20 soulstones to upgrade you hero to Green grade
- 50 soulstones to Blue grade
- 100 soulstones to Purple grade
- 150 soulstones to Gold grade
Soulstones are obtainable through Campaign elite levels. When you get Elite level to 3 star, you can instantly sweep that stage, even 10 times in a row. If you have enough stamina for it.
My might: 60 Million
Castle level: 25
