All four blood magic subclasses for the casters have some variant of their main blood magic ability, however, regardless of their focus. For wizards and sorcerers, that ability is called Hematurgy. Like the blood mages of Dragon Age, these blood mages can spill their own blood to fuel their magic even when their normal spell reserves have run dry, recklessly harming themselves in the process. This subclass for the sorcerer actually gets bonus hit dice to spend on that feature, and extra healing to make up for the damage, as a way of tying the sorcerer’s default “magic is in your bloodline” theme to the specific “blood magic” theme.
Fist of Flame is intended to be a simple-to-understand single-target damage spell, fitting into the lineage of blight, harm, disintegrate, and finger of death. As an eighth-level spell, fist of flame gets to pack some debuffing power with its damage punch. Blood to Flame is both a new Pyromancy spell and a new Blood spell (what a fun venn-diagram!) you can use to torture your enemies as they die a gruesome death.
The gore spike cantrip offers a Constitution-based alternative to firebolt for simple damage; blood boil is a potent at-will (concentration) debuffing cantrip with short range and minimal damage; and blood extraction is a 3rd-level area spell that damages enemies over time, dealing more damage to bloodied foes, and absorbing the blood of defeated foes for your consumption.
