->'''[[@/LeChuck4 GG]]:''' Whoa. That's neat. I wish I could do that.\\
'''[[VideoGame/DokaponKingdom Erik]]:''' Don't you have the ability to say you have that power then makes it so you have that power or something?\\
'''GG:''' Well not exactly. I can only do that when I'm not exactly doing it on purpose. Because when I do it on purpose, I'll have to pay the price. And I really don't like paying the price.\\
'''Erik:''' Oh... Can I ask what the price is?\\
'''GG:''' Blood and/or physical health. The amount of price is always related to the impact of what I change. But the exchange rate is horrible. Remember when I said I lost the bones from my right hand? That happened after I changed Asagi back into a human. It's always very-- Oh, you know what? Let me just show you. ''[GG looks at Erik for a moment]'' You are orange. ''[Erik's green features turn orange, and a large cut appears on GG's left cheek; he bleeds [[Webcomic/{{Homestuck}} rainbow-colored blood]]]'' See? I just changed your color and what I got is a nasty cut.

->''"While the [[SupernaturalElite aristocratic vampire bloodlines]] bestow potent supernatural powers, [[EvilSorcerer some]] devote themselves to further occult study, honing their magical craft. Cut off from [[{{Mana}} anima]] as a source of power, they have learned to cannibalize the energies from the stolen blood in their veins. This renders them physically weaker than their earthier kin, [[LeanAndMean emaciating their frames]] with the purge of every ritual. They claim to require the blood of the magically abled, but this is an affectation rather than a scientific fact."''

->'''Kintaro:''' I'm sorry, Ranma, but all the signs point to this being a blood spell of some kind, and spells cast with blood are not only nefarious and unscrupulous in the extreme, but very hard to break.\\
'''Ranma:''' A blood spell? What the heck is that?\\
'''Kintaro:''' Just what it sounds like. A spell cast with the blood of a living creature. The more powerful the creature, the more powerful the spell. From what I can see in your aura, I would guess that the blood used was at least human, or possibly even that of a magical animal or spirit beast.

->'''Hadrathus:''' Why have you delayed? Why have you allowed so many of your allies to fall pierced by arrows and spitted on spears?\\
'''Xaltotun:''' Because blood aids great sorcery! Because no wizard wastes his power thoughtlessly. Because I would conserve my powers for the great days to be, rather than employ them in a hill-country brawl. But now, by Set, I shall loose them to the uttermost! Watch, dog of Asura, false priest of an outworn god, and see a sight that shall blast your reason for evermore!

->''Hemalurgy, it is called, because of the connection to blood. It is not a coincidence, I believe, that death is always involved in the [[PowerParasite transfer of powers]] via Hemalurgy.
