Fiendfyre

"Fiendfyre-cursed fire — it’s one of the substances that destroy Horcruxes, but I would never, ever have dared use it, it’s so dangerous."
-- Hermione Granger (DH31)

Fiendfyre

Effect: Creates a cursed fire, made up of flames of abnormal size and heat that can crumble fairly substantial objects to soot at a mere touch. Left burning long enough, the fire will take the shapes of gigantic fiery beasts (including serpents, chimaeras, dragons, and birds of prey) which will pursue any target humans.
