For low-level pets, unless they themselves have extremely good talents, it is very difficult for them to learn a high-level skill.
Therefore, compared to the function of the high-level Dragon Crystal to break through power, David Jones values the effect of awakening the Dragon type skill even more.
Even for Nixon Lowell, who is as insightful as the Sleeping Dragon, his pet, the Three-headed Flame Dragon, has only learned a few Class V skills, not to mention the Class VI King-level skills!
Even in these times of advanced technology, some researchers have created high-tech arcane implements which allow pets to understand new skills in a second.
But those skills that can be learned instantly are all low-level skills, the highest level among them being only Class III.
Those arcane implements for teaching skills above Class III, not only require a longer learning time, but also cost a lot, which most ordinary people can't afford.
