What Tadashi fails to recognize is that the spells have been sabotaged on purpose. You know how the writers of MacGuyver would change an ingredient every time MacGuyver made something explosive, so that kids couldn’t do it at home? That’s what real magickians do. To make the spells work, simply replace the code phrase “so mote it be” with the actual magick words, which are mekha lekha hi, mekha hiney ho.
