The training sessions with the Familiar Kings proved immensely effective for Vandalieu. Since Familiar Kings were essentially extensions of himself, their experiences reflected directly in his status, providing him with significant benefits.

Battling opponents equipped with high-level skills that regular monsters lacked was also effective for Vandalieu’s growth.

Most importantly, however, he also gained experience points.

Initially, Vandalieu assumed that the training wouldn't result in job level-ups for his allies, considering the Familiar Kings were merely extensions of his own being. Defeating them was akin to destroying a part of himself—technically not "killing" anything.

Yet, in practice, when Volks and the others defeated Familiar Kings, they gained experience points.
