I don't see this as a problem, I can always dark arts something else lol. But I like the sole survivor suggestion because I believe it would mean we actually get to spam bloodspiller dark arts free of cost for a few. So just like mana floor first then do that. I kinda see it like a two phase dps system. On the one hand you build resources like crazy, for the other you get to avoid resources for a short amount of time. The trick would be never doing both.
