List of Potions
Clone Spell: Seen in Ethel Everywhere and All Hallow's Eve this potion clones people and objects. Ethel uses it on herself and the founding stone. A pair of kippers in a pair of slippers is the essential ingredient of every clone spell; using another kind of fish makes a clone that is not exact. To clone a witch: 'Let this witch be where she wants, not one place, two at once!' To clone a witch many times: 'Let this witch be where she wants. Not one place, but lots at once.' To vanish the clones: '. All other versions of me be gone... Let I alone be the only one.'
