The witches and wizards who can cast this spell Each Patronus is unique to the witch or wizard who conjures it, and it’s possible, in some cases, for a Patronus to change. The ability to cast a corporeal or non-corporeal Patronus is down to the skill of the witch or wizard. Whereas a corporeal Patronus has a form that is clearly defined and is more than vapour or smoke. A non-corporeal Patronus can appear as ‘a thin wisp of silver’ that hovers ‘like mist’. The Patronus has two forms, non-corporeal and corporeal. And, erm, what exactly is a Patronus?Īs Professor Lupin told Harry in Prisoner of Azkaban, the Patronus is ‘a kind of Anti-Dementor – a guardian which acts as a shield between you and the Dementor.’ It’s also ‘a kind of positive force, a projection of the very things that the Dementor feeds upon – hope, happiness, the desire to survive – but it cannot feel despair, as real humans can, so the Dementors can’t hurt it.’

Harry Potter was one of the youngest wizards to cast a corporeal Patronus, having been taught by Professor Lupin at the tender age of 13. The Patronus is a form of advanced magic which even the most qualified wizards can struggle with.
