After looking at the wiki, it seems there isn't particularly much room for both being well versed with magic and having decent enough physical capabilities to wield a weapon. 

Might go try and go for Dhampir -> Vampire Noble -> Ice Blood True Vampire then, but I dunno. Fits the more elegant theme I eventually want for Isurta, but I don't want to rip off a cannon character too much.

Spell Lord is another option, but eh...I don't want to just use magic. Sort of a combination of both. 

Something that's relatively agile and has decent physical capability as well as a decent understanding of magic. Something speedy, can do ninjaflips, and that can hurl a fireball or two, to put simply.
