Once per turn, when casting a spell, choose one:
- Use HP in place of Mana Points.
- If the target is affected by your spell, you regain HP equal to your Prowess.
Mastery
You gain additional skill in casting Blood-type spells.
Draft, and the source itself needs real editorial attention, not just terminology fixes: it contained two overlapping, slightly different versions of the same bullet list (looks like two draft passes left in the same block — a second version offered “spend HP to add an effect” and “regain HP equal to level” instead of Prowess), and the Mastery section cut off mid-sentence (“double prof when casting, double your—”). Reconciled here to the cleaner of the two passes and used “Mana Points” in place of the source’s “Spell Points,” but the Mastery benefit is genuinely incomplete in the source — not guessed at here.
