Skill 2 Fusion

Skill 1-1 Fusion
Changes the first skill of the item to a random max first skill corresponding to that item. Leaves the second skill the same. For a Magic card, it changes the first skill to a random skill with max duration but keeps the percentage the same.
Skill 2-1 Fusion
Changes only the second skill of the item while keeping the percentage of second skill the same and keeping the first skill the same. For a Magic card, it only changes the second skill, while keeping the first skill and both the percentages the same.
Skill 2-2 Fusion
Changes only the percentage of the second skill, while keeping the second skill the same as well as keeping the first skill the same. For a Magic card, it changes the percentage of both first and second skill. Chances are affected by Fusion Mania events as well as Event Card. There is a small chance that the Skill 2-2 Fusion card will drop the percentage of the second skill by 1% but it will usually increase or keep the current percentage.
Skill Fusion
Allows for attempting to fuse a level 9 card to a level 10. Failing the fusion will not change the skill of the item being fused. Chance = 10% + the percentage of the second skill on the item it is being used on. For example, level 9 item with second skill percentage of 32%, will have a 42% chance to level up. Chances are also affected by Fusion Mania events as well as Event Card.
