Forged from Their Blood, I Am Their Reckoning

Everyone calls Yann a reject who'll never awaken a soulblood. They're wrong. Humanity is losing the war against werewolves, vampires, and titans, and other races have hunted Yann in his dreams for years. When his father is sent to the Battlefield of the Gods for saving civilians, Yann vows to get strong enough to find him. Then he awakens the Codex of All Races: devour a race's blood, take its talents, fuse them into a power no one has seen. Tier by tier, he rises to become the Worldmaker.
