Level Up

Aethers can be leveled up to 210 to increase their powers. The higher level ather have, the more ability to win the battle & get rewards. However, there are limited levels can be upgraded for each Tier.

Players should level up the Hero to achieve the corresponding increase in HP and ATK. The higher the level, the greater the stats added, each update will cost a certain amount of Gold.

Note: When you level up a Hero, only HP or ATTACK will be increased (not both)

How to calculate HP & Attack of each level:

	Level n
HP	Base HP*(1 + 0.1*n)
ATK	Base ATK*(1 + 0.06*n)

How to calculate Level Up Cost:

	Level n Super Super Rare (Gold)	Level n Super Rare (Gold)	Level n Rare (Gold)	Level n Common (Gold)
Level Up Cost	9*(n-1)	8*(n-1)	7*(n-1)	6*(n-1)

When a leveled up Hero is sold, all Gold spent to level up that Hero will not be returned.
