- "But then, through the darkness, fire erupted: crimson and gold, a ring of fire that surrounded the rock so that the Inferi holding Harry so tightly stumbled and faltered..."

Firestorm is a spell that produces a ring of fire around the caster. The caster is able to control the movement and direction of the flames with enough precision to strike individual targets. The spell Partis Temporus can create a gap in the flames to allow safe passage through.
In 1997, Albus Dumbledore and Harry Potter entered a seaside cave in an attempt to locate one of Lord Voldemort's Horcruxes. When the Inferi guarding the Horcrux attacked, Dumbledore conjured a firestorm to drive them back, saving Harry's life in the process.
