Helps restore non-corporeal wizards to their bodies
The regeneration potion is a Dark Potion that restores a wizard whose body has become maimed and disfigured to their true and whole bodily form. The potion requires a Cauldron large enough for a grown man to sit in as well as three crucial ingredients: bone unknowingly taken from the Dark Wizard's father, flesh willingly sacrificed from one of his servants, and the blood forcibly extracted from one of his foes. The remainder of the ingredients, if any besides water are needed, remain unknown.
The use of Harry's blood in the potion, however, would come to be a mistake as it prevented Voldemort from killing Harry because the blood passed Lily Potter's protection to Voldemort and anchored Harry to the living world through him, ensuring the Dark Lord's defeat three years later. Voldemort believed that by using Harry's blood, it would allow him to bypass Lily's protection, when in fact it actually strengthened it.
Behind the scenes
- In LEGO Harry Potter: Years 1-4, Peter Pettigrew used Harry's glasses and cranial bone, most likely to avoid violence. Instead of using a knife, Peter Pettigrew simply takes his hand off. When Voldemort is returning he wears Harry's glasses. Also, Voldemort is sucking a dummy as a baby and lies in a pram. Also, Voldemort rises from the cauldron, but already has his cloak on.
- In the book Voldemort rises from the cauldron. In the movie, the cauldron catches fire and melts as Voldemort's body regenerates in mid-air and becomes magically clothed by a conjured black cloak.
