Cedric's Death

Peter Pettigrew (Harry Potter) uses the Killing Curse, reputably unstoppable and irreversible, to instantly kill Cedric Diggory.


The term One Hit Kill refers to abilities that maintain the ability to automatically and, assuming it functions as expected, without fail cause the target to die- therefore, it does not affect physical attacks except in very specific circumstances.

Powers and attacks of these types are by and large considered "Hax" as they bypass all means of traditional durability.
