The MC gained points when absorbing magical energy from a location, so why did the points gained when leveling up only appear?

In addition to powerful wizards, those who study in Africa learn wandless magic

Many stories appear with MC investing in marijuana or tobacco, the funny thing is that many have high intelligence and advanced sciences or magic or something like that, which could cut the harm and even make the use safe and even beneficial, but they almost never do that, They just want the benefit and nothing to invest in improving and helping consumers.

Potions can help with strengthening, but the greatest possibility would be in rituals, at least for permanent improvements.

The magic of Harry Potter's world appears to be a weakened and more controllable version of Marvel's chaos magic, both require strong will and intentions, not to mention feelings can influence their intensity, only chaos magic is stronger but requires a lot of difficulty on its part. controlled use or without influencing the user.

There are some fanfics that can help, I'll recommend some here, to avoid the story continuing to look like a sketch or a diary: Game of Thrones: The Legend of Jon Arctic – ASOIAF/GOT GOT, Head-Patting in Marvel, Marvel: Baldur Odinson (PT-BR), One Piece - I Am A Different Luffy!, Meta Essence Gacha in Marvel. Basically all of these stories can inspire you to improve the construction of the story, narrative and development of the world, events, interaction and the characters themselves. I'm posting more than one chapter to increase the author's chance of seeing it, I hope I can help, the story has potential.

The super brain was missing

This phrase that without a wand a wizard from Harry Potter is just another human is false, it is a tool, it allows better control and ease, but it is not something essential to the point that without it magic cannot be done.

What's wrong with cement and things like that? Roman cement or something similar must exist, even bake bricks, ferment extrume. I would like to remember that the original author was very inspired by Rome to create Valyria for example, besides there is a huge territory based on ancient China, so even paper must exist, MC making use of these things would at most be considered gathering and putting in practice existing knowledge that was dispersed and stored.

Genjutsu acts on chakra energy, right? So much so that to free yourself from one, it is necessary to change the cycle or a disturbance in the chakra, the explanation for it to work is that it is directly affecting mental power? Even if these people don't have chakra?

I have a theory about how Valerian steel is made, in addition to iron it must have a small amount of copper, silver and gold, which are excellent energy conductors, this should facilitate the use of magic, the fire when made must be draconic fire , and after making objects they must be tempered using the blood of beings with magic and the use of Runes, probably in Valyria they use the blood of slaves and dragons.

Was the fact that intangibility can be activated or deactivated because of the change to remove the weakness over the sea?

If it is to have the power of light...a zoan would be better...holy light, he would receive the power of paladins, white light mages and the power of clerical priests.

I still say that characteristics of Harry Potter's lineage of wizards and some of the Custodes or the Emperor himself from 40k were necessary to develop magic and the brain to the point where he could become psychic.

My suggestion of the magical lineage of the Harry Potter world is because they still fit in human beings, and performing magic requires will, intentions and feelings, it's something perfect for the mc, and it doesn't depend so much on the Gods and things like that. The part about the Custodes is that they are also human, and could improve the physical in general, but especially the mind, as a descendant of the emperor, created by the latter's own hand, the potential is tremendous and they could even have psychic powers, which it would match well with the others' magical bloodline and the other two characteristics.

Good combination for the power level of the world, congratulations, I recommend just adding a lineage of Merlin or another powerful wizard from the World of Harry Potter, it was still necessary for the mc to train and perfect the magic, in any case matching the desire His ability to grow as he trains, but it generally combines with the world setting and other characteristics, and perhaps some characteristics of the custodians created by the Emperor in 40K, to increase the possibility of pisikikos gifts and physical potential.

I recommend a zoan fruit, mythical model, Dryad or natural elf, this would make the mc control and generate plants, and receive the love of nature, like animals would treat him friendly, the climate would adapt to help the mc, the land would be more fertile with its mere presence, it should be weaker than the admiral's forest fruit, but it is still an excellent fruit, especially if he decides to study science related to medicine or biology.

Does MC have a super brain? like Superman has and that's what helps him deal with his super senses. I say this because the MC can invest some time in studying knowledge and learning easily with his super brain, then he can mine asteroids and things like that, develop worker robots and other technologies and develop bases outside the Earth and even in the future on the planet itself, he can use mining, satellite launches and other activities of the type to guarantee a huge income, thus changing the dependence on the Vough company somewhat.

They have bodily changes and passive powers. Even if there are active forms of manifestation, such as creating energy fields, creating fire or stretching on purpose. The bodily changes that allow such powers to exist are present regardless, as I already gave as an example in another comment, even when being shot, while unconscious, the fantastic lord's body will passively act like rubber. Changing Ben's appearance through magic is possible, but this won't be basically a power activation or anything like that, his physical power is already fundamentally due to his structural changes in a rock, he fundamentally changed, the entire genetic structure and bodily, it is not something that happens because he simply has no control. It's something like in certain mutants, who, when activating their genes, change without being able to return to their original appearance, only by deactivating and regressing the genes to their previous state can they return to their original normal appearance, but again with the use of magic the mere control of appearance it must be possible. But be careful, don't give readers an idea, as if the physical changes and the powers resulting from them could be something like turning a light on or off, because that's not how it works.
