Hero Rarity Upgrade

To upgrade Heroes the player must spend the amount of it in the following proportion: 7-N (Where N is the amount per rarity starting at 1 for Common and ending at 5 for Legendary, as there will be no rarity above Epic there is no need to do calculations with it) + rate in ZDCOIN.

Example 2: Player B wants to raise the rarity of a Rare Hero to Super Rare, so he needs 7 - 3, totaling 4 Rare Heroes to consume to turn into 1 Super Rare Hero.

The Heroes to be used must be in the previus rarity. Ex: To upgrade to a Legendary Heroe it´s needed 3 Super Rare Potions.
