I could learn house elf magic, study some magical creatures, the meaning of wizard magic, and some senjutsu or natural energy, physical and spiritual energy as well, then try to create a new magical energy, purer, undetectable by having natural energy, it could be camouflaged with the environment, I wouldn't use a wand when learning about the body, about elves and magical creatures. as well as learn from them, You could literally even study runes (I think runes exist in Harry Potter) and once you've studied all of that, with the help of the figures and power style of magical runes, You could create magic by magic circles, magic that would be created without a wand, and only with your voice you could create floating magic circles, taking something from the concept of magical symbols from runesLastly, perhaps create a potion that enhances and increases your magical amount, purifies your body, or gives you access to finer, more powerful and perfect magic. And finally study the soul, and how to strengthen it, if you can improve your soul. In theory things like avadakedabra (death spell) shouldn't be affected if your soul is too strong The other and last thing would be to recruit many house elves "house elves are OP" and create a personal aura of authority, death, despair and fear, Kind of like the "despair aura" of some anime characters like momonga from overlord, You could use that aura to make beings of death and despair like dementors, thestral, And some other magical creatures, by your aura, come to venerate you, respect and swear allegiance, having an aura that makes them want to worship you as their lord
