[@Lucius Cypher]

I wouldn't mind making his cursed blood as magic, though I'm not sure under which branch of magic it would fall since it offers clear physical and magical buffs in the short run, but essentially kills you in the long run.

The soul-stealing was added because this way, I would feel my character would actually get stronger, plus it's a downfall since he loses most of the benefits from this divine protection if he dies.

Though I would be glad to change their powers to something a bit more lore-friendly if needed.
