A blood magician can cope with the drain. So anyone from a magical background where blood sacrifice as even conceptualized, this could even include some of the more 'extreme' ends of the christian spectrum.
As I recall, blood magic is still outlawed and the Draco Foundation has a standing bounty. This is going to make it more difficult for a blood mage to operate in the UCAS (or anywhere else, really), especially if it's in a high-population area. There are going to be people looking for things that blood mages want.

There is one problem with this assumption of 'rareness' people keep floating about. There are an infinite number of infinitely large metaplanes. This means there are an infinite number of spirits of any given description. They may comprise large or smaller proportions of the population, but there is no limit to their number, so that even the tiniest fraction of them would have any known connection to earth is absurd.
But it's still a possibility. If you want to handwave it and say that someone can completely stealth cast a magical WMD, that's fine. I'm trying to provide a theoretical framework that a GM can use to foil the attempt, but I can just handwave it and chase you from the table until you come to your senses as well, that's fine.
Mind you, this is the 'you as game-wrecker', not you personally.

It would require a magic of maybe 6-8, so a grade 1-2 initiate. It would need whatever standard binding materials are needed for that tradition, and likely access to blood magic, as well as some cows, or clones, or kittens, and any tradition who's great spirits have earthquake, and endowment to get the powers needed to do the binding and invoking.
Clones require gear that can be tracked - and cows I believe would be rare enough in NYC to raise some flags if a private citizen is trying to get them in suffificient quantity to attempt something of this magnitude. Kittens as well - I avoid kitten bandoliers as a matter of course.

So would I, except that none of the needed materials should actually be rare enough that they will attract attention. It would be like trying to stop someone from building a nuke using materials found only in hardware stores and garage sales. Ya it would be a great idea to stop them, but nothing they're buying is adequately regulated to attract the attention that would justify looking into their activities.
What kind of garage sales are you going to where you can get the radioactive materials needed to start a nuclear pile?
If the materials aren't rare enough to bring in a greatform spirit, perhaps they should be. Or rather, not all of them, but perhaps something specific to bring in that kind of power. Were it me I'd houserule it, and if the player
really wants to go through with it, then someone is going to get wind and realize the threat for what it is.
