*Character can increase their potential level in two ways.
- First,by using their character tokens,their character tokens can be obtained when getting the duplicates of them. Each characters' token can only be used to level up the corresponding charcters' potential. One character token can level up the corresponding character's potential by 1.
- The second way is using profession tokens, which can only be obtained in the purchasing ticket shop. Different rarities of characters will need different profession tokens to level up their potentials. The rarer the character, the more expensive their profession token is. 4 profession tokens will level up a character with the corresponding rarity's potential by 1. Currently, the game opened 6 levels of potential, each one with an enhancement for the characters, such as deployment cost decreased by 1 and talent enhanced.
