Now that the year of the vampire is coming to a close and the gameplay changes appear to be locked in, I would like some clarification.
In the gameplay, a blood scion who refrains from drinking blood retains a maximal amount of their humanity, whereas drinking blood leads to them becoming closer to a monstrous bloodfiend. Roleplay wise, I can definitely see a character not wanting to devolve into a bloodfiend, and so in my mind, there is an argument to be made for a blood scion that refuses to drink blood. However, the idea of a "vampire" who abstains from blood and suffers no ill effects is a bit odd, to say the least.
So, what happens to a blood scion if they abstain, lore wise?
