When Leon heard that, he noticed that it did make sense. Skeletons could have their equipment inside the dungeon, but outside, they had to absorb some mana for them to create those. Considering that they could destroy airplanes in just a few moments and even match their speed… it was evident that they were way too powerful, considering that they only appeared in a world that just obtained mana. Still… Leon was a bit worried about the term 'first stage'… it looked like dragons could evolve into something more fearsome.
"Well, that does make sense… the dragons I saw were only beasts that craved for destruction. They weren't that smart, but if they become smart like humans… is that dragonnewt an evolved dragon or son of one?"
