Unleashes devastating fire


Athene Black 1977 or 1978

"Bloody hell Athene. You could have killed us! What got into you? Unleashing Fiendfyre in this cramped place.
—Fabian confusing this spell with Fiendfyre 

Ignisium was a curse developed by Athene Black during her seventh year at Hogwarts school of Witchcraft and Wizardry which creates a bewitched flame of abnormal size and heat, infused with dark magic that is at the mercy of the caster's will. 

Description and effects

Creates a torrent of bewitched flames to erupt from the caster's wand taking the appearance of a serpent. It is unknown whether the flames can take on a different form.

The flames are easy to confuse with Fiendfyre, though they lack the sentience of the latter and are much easier to control. If the user is skilled enough, they can control whether the flames burn or not. Making them much safer to use, even in cramped spaces.
