Blood Sorcerer

Blood Magic channels the chaotic volatility of a sorcerer’s blood into raw destructive magic. Through the consumption of their own vital essence, a sorcerer connects with latent currents of ancient, corrupted magic—once wielded by forgotten blood-bound cults. This power grants extraordinary control over spells cast through their blood, but at great personal peril to the user. It also draws on this connection to fuel powerful blood sorcery abilities, feeding off pain and fear to grow even stronger when the sorcerer is injured or weakened.
