Very intriguing question, I don’t think I’ve discussed this with admin dichen before but I suppose yes there is a difference because sorcerers have powers after all so their blood would be more replenishing for vampires. As for the exact effects you can decide for yourself as long as it isn’t too exaggerated (exaggerated i.e. vampires miraculously gaining certain powers by feeding on a sorcerer’s blood)

I don’t quite get what this question means but if you’re asking whether it is ok for your character to be a crusnik, it is allowed. Though under the condition that your character must have a certain weakness made known to the other castes to avoid overpowering. 

We’ve considered it a lot, but we thought it was better to keep the focus on vampires and humans, especially since there are many roleplays focused on werewolves, or the whole vampire vs werewolves thing. We added halfbloods and sorcerers as a caste option for diversity. Sorry dearie!

It means that a sorcerer might take a mortal under their protection in compensation for their power in exchange for caring for their charge (or even teaching them as a sorcerer apprentice). It’s kinda just another way to pay the price of their powers (and to maintain their powers).

Admins have discussed this before and technically vampires are living dead — creatures who require some form of life to sustain their own and that’s why they drink human blood (because human blood = life). so then that sorta makes vampire blood = dead blood. That being said though, vampires are powerful so drinking their blood would improve strengths/powers so it’s up to you to decide which to get for your muse (preferably a mix now that i think about it, but that’s just an opinion)

To answer your question: yes, they would become sicker or possibly even die (after all, if it were possible to become a pureblood by turning, who would still be dealing with the pain of being a halfblood?), but they can try, perhaps with the help of a vampire so they don’t actually die in the process!

Yes, they are! Vampires are not birthed by parent vampires (since reproduction between two vampires is not possible), they are humans who have been turned into vampires.

Otherwise, you could choose an older faceclaim (think older actors/soloists like Hyori, and older idol groups like Shinhwa and Wondergirls), and go for 80+ no problem!
