A signature spell (or signature move) is the spell most commonly cast by a witch or wizard, especially when used in the context of duelling. Even though the spell may be the one the caster is best at, its predictability can make its user vulnerable.
Behind the scenes
- The Full Body-Bind Curse seems to be the signature move of most if not all Pottermore users, as it is the most popular out of all; Furnunculus is the least popular.
- Harry Potter and the Deathly Hallows (First appearance) (Mentioned only)
