The Black Spot!

It's been a week or two... He thinks? Since he started learning under Big Hat Logan, Reima had been like a sponge, absorbing all knowledge presented to him. Due to his undead constitution he didn't need to eat, drink or sleep. The only thing he required was rest for his mind occasionally, sadly the only way he could acquire such a thing under Logan's tutelage was to help him "Sleep" with a gentle thwack to the head. During his breaks Reima rested at the bonfire for a couple hours and decided to upgrade his intelligence to help assist with his training, he reckons he's at around 75 intelligence at this point... But with every soul he infuses into his own, the more are needed to get an appreciable result, with his upgraded intelligence he finds that he's able to separate actions and multi-task easier, this massively helps with his Sorcery due to the way you need to channel Mana into formulae.

His arm is still black, but is healing at a slow rate. It didn't used to ache since his pain receptors were probably burned away, luckily with his ElderBlood's adaptivity his body is able to heal damage that would render normal men crippled.

Logan's lessons included spell construction and adaption, demonstrates this with his own self created spell homing crystal spellmass. He said he'd observed how the soul spear changes from it's normal variant into it's crystal one and managed to get similar results. While he still hasn't cracked the mystery of crystal it's still a massive achievement but Logan seems to think Reima will surpass him eventually. The spells Reima can currently use are Soul arrow, Great Soul arrow, Heavy Soul arrow and magic weapon. The normal Soul arrow spells are relatively easy to cast due to their simple formulae, the ones Reima had trouble with were Heavy soul arrow and Magic weapon... Heavy soul arrow seems similar to it's regular variant at first glance, only noticeable difference is that it moves slower. But it's effect and formulae are significantly different, the act of forming a Heavy Soul arrow is coming close to forming crystal... While not quite physical it impacts the soul like a rocket at a tank. Magic weapon was also an issue at first, due to it's unconventional formulae. Reima was used to offensive spells that had a target, instead the magic weapon spell is essentially covering a weapon with a large soul arrow that retains it's shape and form... When striking with such a weapon it would attack the soul as well as the damage the weapon would initially do.

Nevertheless Reima managed to become adept at casting these few spells, he's also broaching the subject of editing Soul arrow with pyromancy but Logan smacked him on the head for trying something so "Idiotic and brainless"... It seems he's not as knowledgable about pyromancies as he is about Sorcery. Reima is sure with enough tinkering he create a Flaming Soul arrow...

Reima also managed to find time to meditate and practise his Haki, he'd been neglecting it since he's essentially been in constant battles aside from his previous visit to the spider sisters with Solaire. With his increased soul level uses Armament Haki has become significantly easier, he notices this when he used it to stop the Iron Golems punch towards Solaire, he'd managed to cover half his body in the black substance which surprised him, he'd hit a wall back in Kaer Morhen and was only able to cover his hand in it... Such improvements can only be attributed to his more powerful soul.

Observation Haki has also been gradually improving as his soul level increased, before he only used it as a sort of radar, looking around for enemies where he couldn't see and especially in his blind spots. The improvements he can actually feel are increased reflexes and awareness of his surroundings, he's not able to read into aura's yet due to their seemingly endless complexity but with enough practise he's hopeful he'll be able to one day. He looks around at the aura's of the people in the shrine and one thing becomes apparent, the Dark Sign gets larger depending on how hollow you are... The CrestFallen warrior sitting beside the bonfire has a massive black spot over his heart that only seems to grow with time, Reima expects him to go hollow relatively soon... Everyone else is relatively normal apart from Logan, he had a Dark spot almost as big as the CrestFallen warrior but it seems to be shrinking? Perhaps teaching Reima has given him something, a purpose? He looks down at himself for the first time and finds an insignificant dark spot on his chest... He sighs, he hasn't been here for centuries like the others so he's not even close to hollowing, he has a goal which probably helps as well.

Last but not least he attempts Conquerors Haki... He'd tried to master it in Kaer Morhen but he didn't even manage to use it, he'd assumed it was for the same reason his Armament Haki was bad, he had a weak soul... His guess seems to have been incorrect as he is still incapable of even mustering the smallest use of it. Perhaps he needs a catalyst of some sort? He remembers that Luffy manifested it while trying to save his brother Ace. Such a story device is annoying Reima, where on earth is he going to find something like that? He's definitely not going to put his loved ones in danger just to achieve a power.
