SSS Awakening: I Can Grant Legendary Classes To Others

In a world where only the awakened matter, Alicar Soulveil was born with nothing. After the apocalypse descended, every human had the chance to awakenen a class. They would then gain access to the Eternal Realm and its many Layers, seeking treasures and gaining tremendous power. Alicar failed his awakening and was judged to be a failure, abandoned by his friend group and society. But right as despair overtook his being, he gained a new class that changed everything. [Soulless: You can make contracts with other awakeners, granting them an additional class, which you will gain the skills of.] However, that was not all, because Alicar also unlocked a unique talent that allowed him to evolve his skills infinitely! Armed with these new powers, Alicar would make sure to acquire as many classes as he could, and set out to become the strongest being in existence. — Description from novelcodex.org
