「As I thought, it’s no good.」

He had tried the same thing on Bone Man and the others, but they hadn’t undergone any change… Though he did get the feeling that their bones were shinier and the cracks in them had disappeared afterwards.

But the Skeleton General and the Living Armors he had encountered in the Dungeon had become visibly stronger.

『Maybe you haven’t met the requirements for them to increase their Rank.』

「Requirements?」

『Yes, I’m not very knowledgeable about how monsters increase their Rank, but if it’s like how people’s Jobs work, I think there are requirements besides increasing their level.』

According to Darcia, Job changes sometimes required several conditions other than reaching a certain level. For example, even if an adventurer with the Apprentice Mage Job reached level 100, their skill with magic had to be of a certain standard to advance to being a Mage – to be precise, they required at least one skill at level 2 or above.

There are other examples that are not limited to skill requirements. A Job change to Knight requires one to be knighted and one must possess a magic sword in order to become a Magic Swordsman; certain ceremonies or prestige and possession of certain items could also be requirements.

Also, one needs to be a beast-man to become a Beast-fighter, a requirement that one must be born with.

Darcia’s suggestion was that perhaps there were similar requirements for monsters to increase their Rank.

「So then, that Skeleton General and those Living Armors had reached the required level to increase their Rank, but weren’t able to do so because they didn’t meet the other requirements. And then when I poured my Mana into them, those requirements were fulfilled and they increased Rank, is that right?」

『That might be the case.』

「I see.」

It did make sense now that Darcia said it. Goblins did not become Goblin Mages and then learn how to use magic; Goblins with talent for magic who then became proficient with it increased their Rank to become Goblin Mages.

In other words, there was no easy shortcut such as pouring Mana into the monsters to have them increase their Rank.
