Verdimillious

• Incantation: Verdimillious
• Pronunciation: ver-dih-MILL-ee-ous

• Type: Charm

The Verdimillious charm's only appearance in the original novels is during the Third Task of the Triwizard Tournament. Before the champions entered the Hedge Maze, Albus Dumbledore instructed them that if they got into trouble and wished to be rescued, they should send red sparks into the air from their wands. During the task, Harry Potter discovered Fleur Delacour being attacked by a bewitched Viktor Krum. To signal that a champion was in distress, Harry cast the Verdimillious charm:

• “He put his wand to the sky and muttered, 'Verdimillious!' A jet of green sparks shot from the end of it, soaring into the dark sky.” - Harry Potter and the Goblet of Fire

The green sparks successfully alerted the tournament officials, and Harry Potter heard Hagrid's voice shortly after, confirming the signal had been seen. Although Dumbledore had specified red sparks, the green sparks produced by this spell served the intended purpose of a distress signal.

The difficulty of learning Verdimillious is unknown. As Harry Potter was able to cast it successfully under duress in his fourth year, it is likely not an overly complex piece of magic. There are no known counter-spells; as a signal charm, a direct counter is likely not applicable.

The incantation Verdimillious appears to be derived from Latin.

• Verdi-: From the Latin viridis, meaning “green”. This directly corresponds to the green sparks produced by the spell.
• -millious: Likely a pseudo-Latin suffix related to mille (“thousand”) or the English word “million,” suggesting a large quantity or shower of sparks.

The name can therefore be loosely interpreted as “a thousand greens” or “a million greens.”

• In the film adaptation of Harry Potter and the Goblet of Fire, the spell used to send up distress sparks is Periculum, which produces red sparks as per Dumbledore's original instructions. The Verdimillious spell does not appear in the films. (film)
• Verdimillious is featured prominently in several Harry Potter video games, where its function is significantly expanded. In games such as the PC versions of Chamber of Secrets and Prisoner of Azkaban, and the console version of Goblet of Fire, it serves as a multi-purpose charm. Its effects include revealing hidden or invisible objects and platforms, and also as an offensive spell that shoots a damaging ball of green energy at opponents. Advanced versions, such as Verdimillious Duo, also appear. (video game)
