Ritual master in HP

I died. You know the way. Truck-kun did kill me and now i sit opposite of R.O.B. "So you're the next person that i will reincarnat huh?" I just could answer "It seems so ... Sir?" I look at the R.O.B and it looks like he Smiles a little "You dont need to be that respectful mortal" 'But wouldn't it be appropriate as you are so much stronger than me and could send me with a sneeze in oblivion' was the only thing i could thought of in the moment. "So lets get over with it i need to reincarnate a lot more people after you, so you have 3 wishes you could wish for anything but too overpowered things".

"Do i need to wish that i could Keep my memories, for the world, for my Appearance or background?" "No need for that to waste your wishes for that after all its too easy to change such things and they are not worth to be wishes". It would seem i got a more friendly R.O.B 'I think for my first wish i want to have a supreme body that is ageless has no limits to evolve and no limiter for magic as well as the biggest mana pool possible as well as high iq, second i want the best talent in rituals, potions, runes, wards, mind and soul magic, and all elemantal magics my third wish would be an soul bound book that write all discovered rituals, potions, runes, wards, mind and soul magic, and elemantal magics in itself, keep track of positive and negative effects and keep upgrading all the things to maximize the positive impact and minimize the negative ones. That should help me really much in Harry potter verse. Should i use an extraterrestrial background so that i can explore the galaxie and much later the universe?' "I want to reincarnate in Harry Potter, my appearance should be like Jeremy Irvine just with black Hair and Heterochromia i want the right eye to be emerald green and the left eye to be sapphire blue. You read my mind dont you?" R.O.B smiles "Of course i do" "Are my wishes possible?" "Sure they are you just need to choose an background and than you can go"
