After a filling breakfast the duo return to the house, Ciri seems a little chipper than before they had left and immediately goes to her room with a book on Occlumency in her hand. Reima decides it'd be prudent to continue looking through the books in the secret library, the dark books with innocuous titles remind him of the huge pile of books inside his Folded Space relating to necromancy, he still hadn't really looked at them due to there being more pressing things to learn. While Necromancy seemed useful at it's highest levels, it'd take a while to get there, plus he'd likely need to remain in one place for an extended period of time to actually make use of it as one of it's strongest features is creating armies of the undead to do your bidding. While that would be useful it'd also cause basically everyone to hate and despise him for using such "Dark" magic... Especially in the Witcher world, if he popped back up out of nowhere with an army of undead in tow he wouldn't be surprised if Geralt also went against him... That's not to say there aren't useful spells in the Necromancy school, he quite vividly remembers the spells from Diablo 3's Necromancer class, as that game had you moving basically almost constantly along with the limited number you could use at a time, all of your spells had to be useful in some manner or another. He thinks back to the corpse explosion spell and wonder how useful it'd be in his arsenal, he does already leave a mountain of corpses in his wake as it is.
Either way he's not planning on learning any Necromancy right now, instead he focuses on Hogwarts base subjects as he's only around halfway done until 7th year. The first few years don't actually have that much practical spell casting when compared to later years, the reason for this is obvious... Most spells could go horribly, horribly wrong if you didn't know enough about what you were trying to achieve. An example of this would be trying to "vanish" something, essentially disintegrating it. If a novice were to attempt it without a clear picture on what the wanted to happen they could just transfigure the object into air, this visually has the same result but it is also one of the most dangerous things you can actually do... As air, oxygen is absorbed through our lungs and utilised by most of the body, what do you think would happen if the transfigured air suddenly turned back into it's base materials? Yes, instant death. Imagine the oxygen in your blood turning to stone or glass... The reason for this is Transfiguration generally always returns to it's base form eventually, the only way to circumvent this is to apply ambient magic gathering runes on it. Of course there is another branch that allows for permanent transfiguration, it's called Alchemy... No, not the school of potion making from the Witcher world, this is entirely different.
Essentially it's rearranging the molecules to form what you want, the problem with this is that it's extremely difficult to master or even change a basic object, this is the reason why Transfiguration is the more popular school of magic. There are however notable people who've "mastered" alchemy such as Albus Dumbledore, Nicholas Flamel, Merlin and a few other names less notable in Reima's opinion.
Reima himself had tried to dabble with Alchemy, with his intelligence vastly increased via his soul level he found it manageable without a great deal of experience... However more advanced techniques still alluded him. He muses to himself that only people with Eidentic Memory would truly master this art.
His study in runes had been accelerated greatly from his examination of the Wardstone binding the vampire trio, just seeing the masterful way in which runes could be combined and used had expanded his horizon for the subject. He still wasn't confident in applying runes to anything and not causing an explosion, and as such would have to wait until he actually attended Hogwarts.
Charms were interesting enough... He wasn't really that into them to be honest, the reason for this being he considered most of the combat spells useless. Why bother stunning, binding, or blinding someone when you could just outright kill them? On the other hand there were a few spells he did wish to learn, the main one being Avada Kedavra : The killing curse, Expecto Patronum : The Patronus spell that is the only known defence against Dementors and a few other utility and healing spells.
He wanted to try cast the Patronus but had no idea what'd happen if he did, he thought it best to try it at Hogwarts under supervision... A pointblank explosion is the last thing he needs, that and the large amount of magic it'd presumably use would alert the Ministry to his presence.
Last but not least would be his progress at becoming an Animagus, with the version the Marauders used being unavailable to him he had to do it the long way. This included a huge amount of meditation and self reflection, the latter being something Reima wasn't good at or liked to do. He still hadn't found his animal but he felt he was slowly getting closer, with the notes he'd found from the Secret Library he felt his progress would accelerate if he followed some of it's suggestions. It also provided some information on what the writer thought would happen if a purely magical being tried the transformation. They speculated that they'd likely become a magical creature as mundane flesh can't become magical, this only confirmed Reima's hope/speculations. He was looking forward to discovering what his and Ciri's magical Animagus transformations were.
Just catching up on Reima's magical progress... :P
As always, if I missed anything please let me know.
