Author mentioned in the world of overlord a person's physical strength is decided by 3 things

basic strength (decided by race and training) + levels (the power of evolution) + class build (mysterious power from the laws of magic)

2 human with same class and level can still have different strength based on their gender and training. Could this mean level 100 npc like Aura and Mare can still become physically stronger by gaining muscles when they grow up.
