I’m the Third Son of a Noble, but I Became the Strongest Mage by Tweaking My Stats and Modifying Every Spell!

Chris, the third son of the Ford family, is considered a disappointment despite the expectations placed on him. Nicknamed “Useless,” he is disinherited at just twelve and driven from home. In the library, he finds a strange grimoire that lets him adjust parameters and alter different kinds of magic. Passionate about magic, Chris eagerly experiments with the grimoire, modifying spells and casting them one after another. He sets out to live freely, spending his time creating original magic, but difficult challenges keep appearing. Unaware of how powerful he has become, Chris resolves each crisis with ease, without even realizing it.
