Incendio Duo is an elementary charm that conjures flames; the average first or second year student can perform this spell. As a more powerful version of Incendio, it conjures flames of a greater intensity. However, the Incendio Tria charm is more powerful than this spell.

Behind the scenes

  • This spell was meant to be in the Game Boy Advance version of the video game adaptation of Harry Potter and the Goblet of Fire. This is evidenced by the game's debug menu, which is inaccessible during normal gameplay but can be accessed via a cheating device such as an Action Replay. One of the options is a list of all of the text in the game, with "Incendio Duo" being listed along with the game's other spells.
