The Severing Charm (Diffindo) is a charm used to precisely and accurately cut something.^[1] It is taught in second year charms classes^[4] and Fourth year classes,^[5] and if used inappropriately can cause death or injury.^[1]

A spellbook for this charm can be found in one of the Herbology greenhouses;^[2] this is also detailed in both Book of Spells^[1] and The Standard Book of Spells, Grade 1.^[6]

History

This spell was invented in the fifteenth century by seamstress and witch Delfina Crimp. She made the spell because prior to her discovery, cutting spells were apt to burn or shred things. However, a fellow seamster Snickerton, 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]
