In the "All-Star Fighting" game, when a fighter upgrades UR, Royal Certification is a key breakthrough prop. If you are a big shot, then there is no hesitation in buying this prop. But for civilian players, they can consider purchasing it later to provide support for core breakthroughs.
These props can be obtained in daily shops and certain activities in the guild. Unless you have special needs, it is not recommended to spend diamonds on purchasing.
These props are mainly used for equipment engraving, and it is not recommended to use diamonds to purchase them. If you are a boss, you can choose to buy unstable core.
The remaining pages of the secret scroll will give the secret scroll experience points, but it is not recommended to buy it.
Each vitality popcorn restores 50 points of stamina. This is a must-have item. Whether you are a civilian player or a boss, you should try to buy it as much as possible.
Each vitality bun restores 10 points of vitality. This is another must-have item, and it is also recommended to buy it in full.
