Harry Potter But AU?

Harry's pov

It was 10:30 pm and I was at my room, tomorrow we would go to London and to Diagon ally to buy all the other things I might need that aren't at the list. As a present my parents will buy me a really good telescope (lucky dad makes a lot of money from the cars he made) and I said that with all my left money from shopping (50 gallons) I am going to buy us all kinds of cool sh*t.

But now I am going to understand why does all the magical people uses wands!

So after reading the entire magical theory book and understanding it I took out my wand, I could right away feel my magic rash to it, I did opened my charms book to the page of the levitation charm, pointed my wand at a pen and said "Wingardium Leviosa" the pen flew, next I said "Wingardium Leviosa" while moving my wand in a swish and flick and finishing while pointing my wand at the pen and instantly, my magic left me and my pen flew up till it touched the ceiling. After cutting my magic and the pen fell, I pointed my wand at the pen and only willed it to raise, just like I did without using a wand, it worked, that's when I understood the way wands work, they are training wheels! When you don't have a lot of magic and also a good grip on your magic and intent using a wand and movement is a great way to drow the magic out and words are perfect for sharpening your intent, when it was created it was probably a way to teach children magic as till the age of 17 your magic develops the most(according to the magical theory book), but after a few centuries, probably by the time of witch hunting this was forgotten and became the only way to use magic.

It's pretty good device if not for the downsides

1) If you don't learn how to use magic without a wand, you will never be able to do it except for maybe some party tricks

2) as Ollivander said every wand have specialties of its own, and I think after using only wand magic for a few years, your magic becomes tuned to the specialties

3) wand is like a helper in using magic so you don't use as much as you should, while it's a good thing when in battle or at hard work with not a lot of magic, when you practice you lose the building of magic you get while exercising your magic. It's like a muscle, when you need help to lift something heavy it's great to have someone to help you, but when you're doing sets of Weight lifting it won't be help if someone lifts the weight with you.

So it's decided, unless I'm in battle I won't use my wand for magic, but I will make everyone think I use it, no need to show all my cards...

Next morning

After waking up and eating a special breakfast (pancakes) we drove to London, we arrived at 10:30 at a technical store and bought a celestial telescope, than we went to Leaky Cauldron, it was super easy to find, we just went to Charing Cross Road and asked around for the pub and in five minutes we had arrived, after entering Diagon ally again, I heard mom whispering "it wasn't a dream, it's really this lame" after laughing out loud we started walking and looking all the things there was. Dad was excited about the Quidditch store and game while mom about the weird candies they had, so after thinking what to buy we decided to buy the basic enchant your own broom so we could enchant a car (that's the dream baby) and a little from the candies: Bertie bott's beans, cauldron cake and chocolate frogs

While deciding to come each birthday to try something else.

After looking around for another hour we went inside a place called knockturn alley, it looked shady but by our standards everything looked shady and in the books they didn't really explain why this place is bad, if it was illegal won't it be stormed by aurors? So I didn't say anything about the place and we went in, after a few minutes of looking around at the place which except for being lighted badly didn't look as terrible as you would think by reading the books, we came to the most special store of Wizarding World- borgin and burkes
