It's true - Nothing provides defense against the dark arts quite like magic, and Fiendfyre is one of the most impressively powerful incantations one can use during battle. What does this mighty spell do?

Fiendfyre is a powerful defense mechanism, producing enchanted flames of great stature and heat capable of destroying anything in its path, including Horcruxes. Even more impressive - The massive flames often take the form of large beasts!
