Thank you for the chapter, I may not be able to give some advices in the future as I'm starting to review for my licensure examination so hope for the best my dear author... Though sometimes, if I can, I may vote for your polls or share some ideas I think can give color to the story, again thank you...

Anyways, another great parade of chapters again dear author, may you continue to have wonderful ideas.

Maybe just focus in the current verse for the moment, and think about the multiverse travelling as the story progress but don't overdo it yourself, sometimes things like these makes people confuse and lose ideas this suspending their works

Maybe it depends on the severity of magic used... the stronger the ones used, the easier it is to be detected by other wizards even the younger ones, but if it is just a simple spell of inducing the slightest harm as possible to others then maybe only special characters like the hat with many experience, the old man dumbledumb, etc. But as time passes and he becomes proficient with these things, others will find it hard to detect the trace

Maybe because it is in the description, but it doesn't corrupt the MC as he is the source of such magic, only the targets but still can leave traces especially he is still a beginner in using the magic. I can see him using it inside the train to hogwarts to punish those that annoys him, maybe Crabbe and Goyle or the Gred and Feorge twins of Weasleys hehe

The accessory of wand and the magic pets have gone op hahah, but still a great chapter as ever dear author, maybe you can slide your works in grammarly sometimes to detect if there's any grammatical errors that might arise. Just suggesting because there's many out there criticizing works of newly sprouted novels like this... Anyways, thank you again for the great chapter hehe

Maybe not an Aura but a trace of malicious magic then...

Harry potter itself has a romance part so it's okay to have one in your story too, and I think it's okay to have a harem of maximum to 3 like Ms. Daphne, Luna and a new character you may insert. As for the craft the MC can specialize, maybe Sci-Tech Engineering with a touch of Magic (where he may make magic robots) as he is familiar with future ideas from his original world.

I think the unique skill might have an aura of malice by the views of others when he just used it or something similar... Anyways, thank you for the chapter, love the content so far

I think the MC will go to Slytherin house if the (Unique Skill: Demon king of Torment, Lucifer) is detected by that talking hat and it might be the dean, Mr Snape that will do the blood inheritance thingy as he will be caught by him playing with his ability to mold gold by his housemate might be draco himself

Am excited for a new novel to read, and I hope it will end well... So keep up our dear author hehe
