Redactum Skullus is a hex that shrinks the target's head. It is the counter-spell to Engorgio Skullus. This spell may be a variation of the charm Reducio, which is the counter-spell for the Engorgement Charm, where the word Skullus confers specificity to the spell, hence limiting its shrinking effects to the head of the target.
