Severing Charm




Hand Movement





Cuts the target


Delfina Crimp (1400s)

"With the Severing Charm, cutting or tearing objects is a simple matter of wand control. The spell can be quite precise in skilled hands, and the Severing Charm is widely used in a variety of wizarding trades. Useful as it is, this charm should be practiced with caution, as a careless swipe of the wand can cause injury."
Miranda Goshawk, Book of Spells.[src]

The Severing Charm (Diffindo) is a charm used to precisely and accurately cut something.[1] It is taught in second year charms classes,[2] and if used inappropriately can cause death or injury[1].


"The Severing Charm was created in the fifteenth century by wizarding seamstress Delfina Crimp who created it as an easy and convenient way of cutting cloth and thread."
Book of Spells

This spell was invented in the fifteenth century by wizarding seamstress Delfina Crimp. She made the spell because prior to her discovery, cutting spells were apt to burn or shred things. However, a fellow seamster nearly killed her after he raided her shop, having realised that she could do magic, and held her tied up. Nonetheless, upon being released to scratch a wart on her chin the wart brought her wand forth and she disapparated with a sack of gold.[1]


15th centuryEdit

The charm was invented in this time by Delfina Crimp and used by her to make and tailor clothing.[1]



Harry Potter cut Cedric Diggory's bookbag with this spell to delay him from class so that Harry could warn Cedric privately about the First Task.[3] Later that year, Ron Weasley used it to sever the lace sleeves of his dress robes before the Yule Ball.[3]


In June of this year, Harry used this to attempt to defend Ron against some brains that were attacking him.[4] Later that year, he used the charm to detach the front cover of his shop-bought potions textbook to replace it with a vandalised version using the mending spell.[5]


Hermione Granger used this to remove the bindings on Ron Weasley after a fight in a cafe; she trembled so much that she cut Ron with it. She used the spell again to remove a locket from Harry Potter's chest shortly after they were attacked by the dark lord. Between her two uses, Harry Potter tried to break Mary Cattermole free of a chained chair; it failed.[6]

Harry Potter used this to attempt to destroy a locket in the woods, but failed.[7] Harry used this a fourth time to break the ice from the frozen pool where a sword was hidden.[6]

Known CastersEdit


The incantation is the Latin first person active indicative for "to split, cleave or open".
