(Outside Gringotts after a few explanations)
Harry turned to Tek, "so these Decks are part of that Duel Monsters game that came out a while ago but are also filled with the original energy called Shadow magic?" Tek nodded "what Deck did you get by the way?" Harry turned to him and pulled out his Deck, the top card was a Purple card with a dragon on it Mythic-Basilisk, The King of Reptiles (Fusion, Level 12, Dark Attribute, Reptile-Type, ATK:5500, DEF:5500) "Cool you got the MythicDeck, I got this one" he pulled out his Deck which had a purple card on it with the picture of a giant snake Anomaly-Future Predator, Annihilator of Humanity (Fusion, Level 12, Dark Attribute, Dinosaur-Type, ATK:5400, DEF:5000) "That's cool as hell, but the title certainly begs the question of how and why?" Tek looked at the card and nodded "You have a point but let's ignore that for now and get our stuff, you have a wand, right?" Harry shook his head "Well then let's go to my place and I fix one right up for ya" Tek grabbed Harry by the arm and the two were shrouded in shadows before disappearing and reappearing at a mansion "Come along Harry" and with that the two walked into the building.
Tek opened up his trunk and hundreds of woods, items and jewels floated up to eye level out of it "Now Harry, I need you to hold your hands over the woods first, you'll know which wood or woods are right for you" Harry put his hands over the woods until he felt two pulls, he grabbed a black wood from one side of the piles and a white wood from the other "Ah, Mordem Wood and Yggdrasil Wood, quite the conundrum, now the same with the materials" Harry felt three pulls almost instantly and one faint pulling from the other side of the room, he picked up a container of silver liquid, a container with teeth in it, a container with what looked like water in it and walked over to the other item, it was a sliver of black that just wouldn't stay still inside the jar, he then brought them over to Tek. Tek looked them over "Well, Well, Well, it looks like you are a perfect life and death wielder, the silver liquid is Unicorn blood, willingly given, the tooth is a Basilisk fang, the clear liquid is Phoenix Tears, willingly given, the black sliver is what remains of an Obscurial that I found in New York, all are classified as life and death materials, my wand is a 12 ½ in cypress wood with a Peruvian Vipertooth heartstring, now stand back, this is going to be a difficult craft" Tek started by lathering the Basilisk fang in Unicorn blood, then whilst using gloves, and a wand, managed to twirl the sliver around the blood lathered fang like a spiral, he then coated the whole thing in Phoenix Tears before casting a silent spell forming the cores into one and making it into a then spire, he then placed the spire between the two blocks of wood and tapped on them both twice with his wand. The whole thing then glowed, and he used his hands to mould and form the wand. Tek turned to Harry "Now quickly go and choose a focusing gem" Harry ran over to the gems and felt a pull from the emerald, he picked it up and brought it over, Tek took it from his hand and attached it to the tip of the Wand, after five minutes of moulding, Tek took the wand in both hands and handed it to Harry "Go on, give it a wave" Harry waved the wand and a surge of magic flew through the room, Tek nodded and smiled, he then waved all of the items back into his trunk, and grabbed Harry and the trunk and shadowed back to Diagon Alley.
