A few questions/possible bugs concerning magic:
1. Kakuzu (Mansion in city industrial): he happily took my 100k, but does he have anything to teach?
Even with magic 100 and spellcasting 100 I still only get this message when I try to learn something there: "You concentrate energy in the sheet of paper. You feel that you are spending a huge amount of mana for this action.
You get tired and sweat like a horse, but your effort was not enough."
2. Kisame (pool in city gym): is there any point to this anime-lookalike mutant? And should I feel bad for electrocuting his rapist ass (seems to be the only NPC in the game that is killed instead of knocked out)?
3. Magic tooth rot: using grooming spells like Shower or Cosmetica seems to count as dental hygiene since the option to brush teeth or use mouthwash is gone afterwards. But the counter responsible for teeth decay seems to ignore them since your teeth get miscolored, and probably worse, when using purely magical grooming (in my case Cosmetica in the morning and Shower several times a day do to a lot of ... physical activity).
Edit: point 3 retracted. Did some testing: the spells worked fine, but my (old) daily routine didn't.
