Basics of evolving
Scene cards can be evolved to increase their rarity and maximum stats. Each card can be evolved a maximum of twice, so if you have a 2-star card and evolve it twice, it will become a 4-star card and cannot be evolved further. Note that 6-star is the maximum rarity in this game so a 5-star card can only be evolved once. This means that to get a 6-star card you need to use a 4-star or 5-star as a base to evolve with.
To evolve a card, you need to meet 3 conditions:
- The base card has to be at maximum level
- The required beli, and
- 2-3 types of evolve materials (check here for when and how to farm them)
- If you have locked the card, it will become unlocked after evolving so remember to do it again if you want it locked.
