Modifier

A modifier was a word attached to an incantation to alter the effects of the spell that incantation was used in; for example, modifiers were frequently used to increase a spell's strength or the spell's direction.

Known modifiers

Horribilis

The Horribilis modifier had only ever been used in conjunction with the Shield Charm which allowed it to protect a large area almost completely from Dark magic (though admittedly it was used in conjunction with other spells).

Locomotor Modifiers

The Locomotor spell altered a target's motion in a variety of ways, depending on which modifier was used with the spell.

• Locomotor lifted the target several feet into the air and moved it.
• Locomotor Mortis bound the victim's legs.
• Locomotor Wibbly caused the victim's legs to collapse.
• Piertotum Locomotor animated a previously inanimate human likeness.

Maxima

The Maxima modifier increased the strength of a spell, possibly to its highest intensity.

• Bombarda Maxima provoked larger explosions than Bombarda.
• Flipendo Maxima knocked the target further back and with greater force than Flipendo.
• Glacius Maxima induced more damage than Glacius.
• Lumos Maxima produced a brighter light than Lumos.
• Protego Maxima produced a stronger shield than Protego.
• Aguamenti Maxima produced a stronger jet of water than Aguamenti.

Numerical

The numerical modifiers were Duo and Tria. When each was attached to a spell's inantation, they increased its strength and could potentially change the spell's appearance, Tria more so than Duo.

Revelio

The Revelio spell was used to reveal hidden information in various forms, depending on which modifier was used with the spell.

Uses

• Specialis Revelio - revealed enchantments cast over an object or the ingredients of a potion

Solem

The Solem modifier was only ever used with Lumos, which converted its harmless, all-round glow into a harsh ray of light, though it is unknown what would happen (if anything) if used in conjunction with other spells.

Appearances

• Harry Potter and the Philosopher's Stone (film)

Total

The Total modifier had two forms (Totalus and Totalum), both coming from the Latin totus meaning "as a whole". It appeared to spread the original spell's area of effect.

Uses

• Petrificus Totalus
• Protego Totalum

• Harry Potter and the Prisoner of Azkaban (video game)
• Harry Potter and the Deathly Hallows
• Harry Potter and the Deathly Hallows: Part 1

Behind the scenes

• Modifiers are much less common in the books than in other media such as in the films.
• Modifiers appear to be able to be used in conjunction with other modifiers to get the combined effect of both, as the Full Body-Bind Curse (which contains the total modifier) can be used with the numerical modifiers.
• It is possible that the Locomotor modifier is also combined with the Total modifier in Piertotum Locomotor.
• It is unknown whether Maxima or Total is the strongest. Total means the spell has reached it's total amount of effect, and Maxima means the spell has reached it's maximum effect; which is in fact two different words for the same thing.
