Boss Monster?

Nial might be unable to see the Boss monster of the two-element dungeon, but he could clearly sense its outlines owing to the distinct mana fluctuations it released.

On the first evaluation, it was almost as if the Boss monster was just a larger version of the Ratmen with horns jutting out of its head.

However, that was not the case and it was more like a large part of the horned bipedal beast's body that had the facial features of a rat was, in fact, manifested from earth transmuted mana!

The physique of the Boss Monster was bulky and Nial felt that it had a striking resemblance to the physique of a furry Minotaur, which was a beast he had first read about in a book in Katu's library.

This was interesting, but also a clear indicator that the Boss monster was not only able to use an elemental affinity but that its physique was not to be underestimated either.
