Hm...alright, KoL, can I add simple magical spells to Rui-Ling's skillset as well then? With the idea that he can supercharge those by feeding them souls too.

What power level should we imagine our characters at then? Something like the human Masters in Fate? Like Level 3 Misaka soldiers?

And in regards to Youkai's firearm immunity...is it because they're spiritual beings, meaning that all purely physical attacks are useless against them, or is it because their durability is simply beyond that of, say, sniper rifles and such?
