I personally think Light And Dark Magic should depend on your Purity/ Corruption and give bonuses depending how far along either path you go. In addition you can do a sub-set of magic off light and dark for the deeper you get into the morality. For example if your corruption is over 80 Demonic magic will become available while 80 Purity will unlock Holy magic and if your Purity/ Corruption goes under 80 you lose access to that branch of magic. This will allow players to plan out the path they want to go considering there's a tangible benefit to pursuing one path in addition you could give benefits to joining one faction like for instance corruption will increase Intelligence or Mana at the cost of health or wisdom while Purity would give more health and wisdom or Charisma at the cost of speed or Mana. giving benefits like those would be great I imagine. Also you mentioned the possibility of a Futa potion later on but wouldn't that be better as a Demonic spell as well as a spell to subtly corrupt or tempt other male students into sleeping with youPlanned for sure, and th encyclopedia is just the place for it! Getting blessing information might be a bit tougher than just "in a book" though. The churches aren't exactly keen on sharing all their secrets. Might have to find a priest that knows and "convince" them to tell you about it for an especially rare blessing or curse
I think for now I'll add the information about them to the wiki though! Since such updates will be a little while! I'll try to get on that as soon as I can !
Light and dark magic are planned for their own sets of classes, dependent primarily on if you have the blessing of light or curse of darkness to unlock in the future.
