The only use of it know of is as an ingredient in a certain recipe in the Arcana mod, but a few bloody rags can substitute, and there’s a tool that can be used to make you bleed, so it’s not at all necessary…
I think there’s supposed to be some kind of quest using the centrifuge in the hospital that never got finished.[/quote]
Yes I’ve gotten this mission, but not completed it. The NPC gives you a vacutainer and tells you to use it on a zombie you kill then take it to a specific centrifuge at a hospital. The one time I did it, the centrifuge had been busted by a brute or something stuck in the room with it, and I looked for another in a different hospital, but that ended me…
Anyway, wouldn’t you just need a tube/vial of blood for the centrifuge… and we already have syringes. Maybe just use a syringe to draw the blood and have a hip flask renamed to a vial or tube, be the container. Or just have a syringe of blood that you take to the centrifuge, and the centrifuge has vials with it.
Maybe you could make some sort of blood draw kit with a syringe, a rubber hose, and a container of some sort.
There are cigars in the game, maybe some could be fancy with a glass tube similar to a chemistry tube or vial.
I did see a post about an infinite blood exploit as well, over in the bugs section of the forum. http://smf.cataclysmdda.com/index.php?topic=14748.0
