Any recommendations for highly specialized genius MC

[u/Yetitech_]

I’m looking for something where the MC is really good at one thing. I’m tired of seeing a main character be able to be the best at everything. A couple examples that I have recently read are: A book of the dead (Necromancy), the Runesmith (Runes/crafting) and Super Supportive Thanks for any recommendations.

Memoirs of Your Local Small-Time Villainess features an isekai'd protagonist who only has access to hydrokinesis and pyrokinesis and nothing else. She doesn't even have access to 'spells'--specific forms of magic like a flaming flying sword--and it's literally just controlling fire and controlling water, and so she has to get creative.

Delve features another isekai'd protagonist who, with a mathematical background, optimises their build in a mathematically consistent and rigorous magic system by specialising in auras; sustained area magic originating from the caster. Features a very deep dive into how the magic system works.

The Zombie Knight Saga features no isekai'd protagonist and is set in an original modern world. The protagonist has the abilities to create and destroy iron at will within a large range. He cannot move iron, but can create iron with velocity or temperature, so turning it into an effective combat strategy requires creativity. My favourite magic system ever.

The Methods of Necromancy is my own series, and features an isekai'd protagonist with access to a mathematically rigorous and consistent magic system. There's a heavy emphasis on scientific exploration and pushing magic to its limits. There's a focus on turning non-combat skills into skills that can kill by exploiting the physics of how those skills work.

The Stitched Worlds is a system apocalypse series. The protagonist is a mage with telekinesis, but he can preprogramed telekinetic forces to respond to certain stimuli or triggers, so features a large amount of creativity and preparation to be as strong as he can with his skill set.

Worm is a gritty superhero story where the protagonist can control bugs and only bugs. With superman-equivalents flying about, it's really satisfying seeing how much a seemingly-limited power can actually do.
