Or you can use one person and drain their blood over long time.

[–] sneezycat@sopuli.xyz 24 points 7 months ago (4 children)

Let's do the math...

You can donate three times a year to the red cross (once every 112 days). According to some page, you donate around 10% of your blood volume each time.

That means, for a volume equivalent of 300 people, you'd need to donate 3000 times, which would take around 1000 years.

The vampire is going to need more people, or to keep a person alive 1000 years with vampire magic.

When you're harvesting the blood iron of your enemies you don't have time for ethics. A controlled study managed 4 weeks within ethical boundaries, maybe we can cut that in half unethically. So 14 days, 3000 . 14 = 115 years. So when you torture two people, you could manage to do 58 years. Better start early!

Orrrrrr capture the entire family of your foe and then you can name the sword something super cool about ending family lines

[–] daltotron@lemmy.world 2 points 7 months ago (1 children)

Maybe the sword is just the product of a small cult which drains blood to create it?

[–] prettybunnys@sh.itjust.works 1 points 7 months ago

And then they do really cool cult stuff with the sword?

3 times a year? Where i live you cab give 1/2l every two weeks at a bloodbank.

And i can take more and by that activate a immune response to produce way more.

The same blood bank? You sure that's not plasma instead of blood? Plasma re-makes itself way faster than red blood cells.

[–] Mikufan@ani.social 1 points 7 months ago (1 children)

Yeah twice a month blood, but only half a liter.

[–] ColeSloth@discuss.tchncs.de 1 points 7 months ago

Oh. That explains it. Normally in the US a typical donation is a full pint. Not a half pint.

[–] ColeSloth@discuss.tchncs.de 3 points 7 months ago

You're off on blood production. "Safe" would be once every six to eight weeks for a pint. Plasma can be taken a lot more often. The red blood cells take a while to replenish.

But let's get real. You're not concerned about your enemy feeling well. Force them to take iron supplements and take a pint every other week. They'll likely stay alive that way. Fuck em, right?

[–] variants@possumpat.io 2 points 7 months ago

But remember they are your enemy so you could drain a bit more blood more often to shave a few years off maybe

[–] Rusty@lemmy.ca 4 points 7 months ago

Slaanesh approves

[–] Steve@startrek.website 4 points 7 months ago (1 children)

Or just mix in a few enemies with some normal iron.

Made with the blood of 100% real enemies!

[–] knorke3@lemm.ee 2 points 7 months ago

But then you need to feed them iron-rich foods which could be used to make a vegan alternative instead, expanding your potential market.
