Though his ability to use other skills seemed to be not the result of his hard work, but his growing up.

His Status Effect Resistance was a skill that granted him resistance against poison, sickness, fatigue due to lack of sleep, hunger and other various detrimental or fatal conditions that could be applied to him through magic. This was likely something he had inherited from his Vampire father.

His Magic Resistance, a skill that mitigated the damage and other effects that he took from magical attacks, was a racial characteristic of Dark Elves. His mother, Darcia, also had this skill.

The Night Vision was a characteristic that both of his parents possessed, which allowed him to see even on completely starless nights as if it were daytime.

And finally, Bloodsucking was self-explanatory. His canine teeth had grown unusually quickly compared to his other teeth… It was a skill that he had acquired when fangs had grown on both the top and bottom side of his mouth.
