Lucivar was hoping for a battle-oriented ability.
Considering what lies ahead, he was outright desperate for more battle-oriented abilities.
His next move was to battle in the South Hues Tournament and also kill Caldaros, and both were quite dependent on his individual prowess. As the tournament gathered the attention of many, the participants would be extremely competitive while killing Caldaros most certainly wouldn't be easy.
Other than the fact that he's a Vampire Hybrid and Sunna's avatar, Lucivar knew nothing about him.
Lucivar didn't know how Caldaros fought or what kind of abilities he had.
But he should be very strong considering that he was one of the strongest in the academy.
From the vision he saw back then, Lucivar could tell that Sunna was a Goddess who excelled in fighting.
Unlike Loki, she seemed to be the kind who fought her battle herself.
