Sculptor's Shard

Sculptors shard is an extremely advanced spell of Earth, Fire and Wind, requiring mastery of all three elements. The spell was invented by alchemist Markus Prochnow and is only know to him. His notes on the spell read: My first inquiry into the magic was upon "Sandy" Enzo, whom had once remarked to me if he had to lose an arm to be rich then he'd gladly have the tavern call him "One Arm" Enzo. With this new ability I planned to give him his wish, so I invited him to dine upon the fifth night of the month. He arrived in his usual rags, looking both out of place and confused. Dear Alondra looked oh so distressed with the mud he had tracked in. After she put our meal of hog on the table she excused herself to clean it, leaving only myself and Enzo. We chatted until he had eaten the majority of the hog and excused himself. But I caught him as he stepped out the door, telling him I had a new trick to show him, one that would grant all his wishes. He peered at me wearily, it's as if no one else understands the art of my craft. I pulled a small rod of graphite out of my pocket, then I used the air to pick up some earth from the garden and made a spere around the graphite. I shrunk the orb, squeezing the rod and lit a fire in my other hand heating it. After about a sixth hour or such my product was finished. I held between two fingers a needle of daimond. He asked me what is was, excitedly leaping up the porch steps when I told him. He held out his hand when I explained it was a gift. Then with a gust I shot it into his palm. He jumped back and yelped with pain. Then as I had thought, the elemental energy expanded in his hand, transfusing his entire forearm into gemstone. Offpalced by the new weight of his arm he fell to his side. I called him by "One Arm" Enzo and told him to spend it wisely before I retired behind the door. I believe he did what was in his nature and gambled it off soon after, but I'm yet to actually see the man, so I can't confirm such things. EIther way it is irrelevant. I spent the next week honing this spell until I could manifest a needle in a manner of seconds. Something to note is that if you let go of a needle it will release it's energy, nulifying any transfusion. I coincidentally had a good opurtunity to use my spell when the tax collector came to the door. O' god, look forth upon this evil vermin that I let plague our society no more, for now his head is far shinier and sits atop my lab bench. Now although I am yet to test my theory, I believe the longer you conjure your needle the more energy it should posses, therefore changing more to the target into daimond. What I am saying is that perhaps you could turn some one's entire body to daimond, if you charged the spell long enough. The last detail worthy of note is that out of all the objects I've tested the spell on it only works on flesh. I am yet to discover why, yet hopefully I may when I do further research.
