"Now, Harry, cast a fully-charged Verdimillious Duo Spell. Once cast, the spell will show you objects hidden by dark magic. Use what you find to leave the room!"
Professor Lockhart[src]

The Verdimillious Duo Spell (Verdimillious) is a charm that emits green sparks from the tip of the wand[1]. It is a more powerful version of the Verdimillious Charm. It holds a number of useful purposes, and is rather easy to cast[1].


Professor Quirinus Quirrell taught this charm to his first year Defence Against the Dark Arts class in the 1991-1992 school year along with the Verdimillious Charm and Verdimillious Tria[3]. Professor Gilderoy Lockhart later revised it with his second year Defence Against the Dark Arts class the next year[1].

The Verdimillious Duo Spell create green sparks that have multiple uses. One such use is to do damage to an opponent, hence proving very useful in duelling[1][2].

These green sparks can also be used reveal objects hidden by Dark magic in a blinding flash of white light, thereby illuminating the entire room for a short time[1]. Unlike its precursor, objects revealed by The Verdimillious Duo Spell remain tangible and visible even after the light fades[1]. Nonetheless, green sparks will still be floating around the enchanted objects for a while after the light disappears[1].



This incantation is most likely derived from Latin "viridis", meaning "green" and French "mille", meaning "a thousand". The modifier "duo" means "two" and is common in incantations of increasing power.
