Throughout the Dresden Files, Dresden has used and upgraded many different items as magical foci and tools. My idea is to make a list of these things, by book, to make it easier for DLP members planning to write a DF fanfic. Basic format should include the name of the book, the type of foci or tool, and the canon description of said item. Series Mainstays, (items used throughout the series, unless broken, replaced, or upgraded - will make note of upgrade in each novel). Staff - A staff of lightning struck oak, covered in sigils, and used as a focus in casting spells. Blasting rod - A rod covered in sigils and used for channeling fire spells. Shield Bracelet - A bracelet with tiny medieval shield charms on it. Used for creating force fields that protect against attacks by matter and projectiles such as bullets, but not energy, such as heat. Energy-storing rings - Rings which are enchanted to store a small fraction of kinetic energy with each swing of Dresden's arms, and used in attacks by expelling that energy when triggered. Silver pentacle pendant - A pendant Harry inherited from his mother. Used for various spells. Bob - an intelligent air spirit bound to a skull in Harry's possession. Bob was used by the necromancer Kemmler and taken by Justin DuMourne when Kemmler was killed. Dresden takes Bob when he kills DuMourne. Bob is used as a magical encyclopedia and lab assistant. Leather Duster - A gift from Susan Rodriguez in Fool Moon, which Harry magically improved to armor capable of withstanding military grade gunfire, magical attacks, and to be waterproof and stainproof. Potions - Storm Front Fool Moon Kim Delaney's Circle Design - Three concentric rings of spidery symbols. - a figure of High magic. Three of them, really, one inside the other, like layered walls. - The outermost circle of symbols is a barrier against creatures of spirit and magical forces. - The second circle is a spell barrier against mortal flesh, but you'd need stones or gems or something spaced between the symbols to make it work. - The third ring of symbols is meant to withhold creatures of flesh and spirit. neither mortal nor spirit, but somewhere in between. - A circle like this one is usually meant to hold entities such as demigods and archangels. Grave Peril Cane sword - cane sword inscribed with runes and used to channel magnetic earth magic Summer Knight Rope of Unicorn Hair - used as a restraint, limited to Dresden's apartment Death Masks Blood Rites Bear shaped belt buckle - used to store magical power and temporarily restore it and energy to Harry when exhausted. Its use leaves him pretty much defenseless once he uses up this power. Cane sword - cane sword inscribed with runes meant to help him channel earth magic and magnetism. Dead Beat Proven Guilty Little Chicago - A scale model of Chicago, made with materials taken from the city itself, which Dresden built as a thaumaturgical link to the entire area of Chicago. White Night Shield Bracelet upgraded - can now stop energy based attacks as well as projectile and matter based attacks; upgraded after Mavra takes advantage of his old shield to waste his hand with the heat of a flamethrower. Small Favor Steel Chain - a coil of steel chain, coated in copper, used to channel energy and conduct electricity Turn Coat Sanctum Invocation - ritual performed on the mysterious island in Lake Michigan, which Dresden names Demonreach, which grants him a bit more power in his spells on the island, and which unexpectedly gifts him with Intellectus while on the island. (mentioned because while it's not technically a foci, the Sanctum Invocation does kind of act like one while Dresden is on the island) Changes Upgraded Summoning Circle Design - A five foot hoop of braided copper, silver, and iron. - Each metal strand in the circle's braid was inscribed with tiny, precise sigils and runes in formulae that harnessed and controlled magical energies to a far greater degree than a simple circle. - Flickers of light, like static discharge but more liquid, slithered around each strand of metal, red light, blue, and green dancing and intertwining in continuous spirals. Speaking Stones - stones magically linked in such a way as to promote communication, similar to cell phones. Pentagonal Ruby - contains the sum total of knowledge of the Ways of Margaret LaFey, Dresden's mother; Dresden glues it into his mother's pentacle McCoy's Staff - similar to Harry's own, McCoy gives it to Harry to replace his own, since it was destroyed. It should be noted that nearly all of Dresden's foci are destroyed by the end of Changes. As I said, this is intended strictly as a resource to help anyone intending to write a Dresden Files fanfic. That said, I don't actually have my copies at hand, as I loaned them to a family member, so that's all I'm able to contribute at the moment.
