The Ducklifors Jinx (Ducklifors) is a transfiguration spell that transforms an organism into a duck. Third years and above were able to cast the spell.

Casting and effects

The caster will slash their wand downward to point at the target; a banana-yellow jet of light will shoot from the tip, with what appears to be a duck made entirely of brilliant yellow light soaring in front. When it hits the target, there is a burst of yellow light and when said light fades, the target is in the shape of a duck.


From English duck(ling) and fors (a suffix often used for transfiguration spells) from either the Latin meaning luck, chance" or the English "form".

Behind the scenes

The spell is included in the "5 Spell Pack" DLC for LEGO Harry Potter: Years 5-7.
