First of all, we need to explain the concept of the level of heroic spirits. Taking E level as an example, it is 10 times the ability value of ordinary humans. Assuming it is 10, then D is 20, C is 30, B is 40, and A is 50. EX is immeasurable. This EX is not good. More than 50 is EX, and negative numbers are also EX. For example, the luck of being a mother is EX, whether it is bad luck or good luck...
It should be noted that N times refers to ability value rather than physical fitness.
The meaning of + is that the instant output of this ability attribute is doubled. For example, the explosive power of B+ in a moment exceeds that of A grade. The meaning of - is that the use of this ability attribute is reduced. For example, if you have E-level magic power, which is 10 times the magic power of an ordinary person, but if you have E-, you can only use up to 5 times the magic power of an ordinary person in a battle. The other 5 times the amount cannot be used.
