2. Power Up Fusion

Power-Up Fusion is the process of feeding several fodder cards into another parent card to increase its level and possibly skill level. This process uses up all of the fodder cards and costs coins proportional to the parent card's level.

Each fusion can feed up to 5 fodder cards into the parent card.

Coin cost of fusion is equal to 100x the parent card's level per fodder card, e.g. feeding 1 card into a lvl 30 card costs 3,000 coins and feeding 4 cards into the same lvl 30 card costs 12,000 coins.

The amount of experience gained depends on the element and level of the fodder cards. Cards of the same element type grant a 50% exp bonus during fusion.

Occasionally, likely at random, the experience gained from the fusion will double.

Cards with the type "Fusion Matter" grant incredibly large amounts of experience during fusion. These cards can drop from various stages or be obtained from the Miko and Buddy Gachas.

Cards with the type "Mutation Matter" give the smallest amount of experience during fusion. Due to the coin cost, it is NOT recommend to use mutation matter cards in fusion.

It is best to fuse a one to a few cards at a time, trying to get as close, but not over, the experience needed for the next level. Once you reach close, then fuse 5 cards at once. Those 5 cards may jump the base card more than one level, but you pay fusion costs only for the original level
