From what I see, he is closer to being a mage with a contract binded by blood. Unlike who is entirely supposed to be the blood mage, Riuus hits a slightly different cord that (at least to me) has enough of a different ring to differentiate him from Vlad.

Based on his old lore from Witchking's previous iterations, he is also part-Elf (or some kind of non-human).
