Card Enchanting is used to increase the level of one card by sacrificing gold and other cards. The amount of EXP gained is dependent on the Cost value and Star number of the card sacrificed, with a few exceptions. The gold required to sacrifice also depends on the Star number of the card that is gaining EXP. Higher Star cards require more gold to be sacrificed. The gold requirements listed below are in the following format; One Star / Two Star / Three Star / Four Star / Five Star. Ex. 60 / 70 / 80 / 90 / 100
