Reductor Curse

"...he tried the Reductor Curse again. It wasn’t very effective, but it burned a small hole in the hedge..."

- Harry using the spell during the Third Task. The Reductor Curse is a spell used to blast solid objects into pieces. The incantation for this spell is Reducto. The number of pieces may vary, depending on the power of the curse. If used with extreme force, the object may disintegrate.
