This boggart-banishing spell takes something scary and turns it into something silly. It Is a charm that is used in defence against a Boggart. It causes the creature to assume a form that is humorous to the caster, thereby counteracting the Boggart's ability to terrorise. Boggarts are defeated by laughter, so forcing them to assume an amusing form is the first step to defeating them. Pronunciation: ri-di-KULL-lis
