“That spell of cursed fire. I don’t suppose it’s a sacrificial ritual that even a child could use, if he dared?”
The Defense Professor’s lips twitched. “It requires the permanent sacrifice of a drop of blood; your body would be lighter by that drop of blood, from that day forward. Not the sort of thing one would wish to do often, Mr. Potter.

One drop is roughly 1/20th of a milliliter. Blood donations routinely take 500 mL of blood from people without immediate ill effect; only some people get dizzy. It would take 10.000 such rituals to reach the negative effect of a single blood donation. Albeit there is of course a difference in that the latter’s volume loss is quickly recovered by the body after drinking some water, which wouldn’t happen with the ritual. Still, I doubt any ritual would be completed anywhere close to 10.000 times, making the permanent blood loss penalty trivial. Quirrell’s line failed to scare me in the slightest.
