Type: Curse
Description: Like the Avada Kedavra curse, it kills (or freezes) the victim. It turns the body grey/blue (or paler) while it turns to stone and then another twin jinx can blast the body into pieces.
Seen/Mentioned: Molly Weasley used the curse after Bellatrix Lestrange attacked Ginny Weasley. Only used in the film version.
Notes: This may be Duro or a Freezing Charm, although the latter is shown to be blue in 1992.
