12 Most Deadly Spells In The Harry Potter Universe

3. Engorgio Skullus

Having your body twisted out of shape until you die is one thing, but how about having your head swollen to grotesque size? That's what the Engorgio Skullus hex offers.

It's a variation on the simple Engorgement Charm, targeted specifically on the skull and any surrounding tissue to give the victim a giant bobble head. It sounds comical - and indeed, it exists in the Harry Potter LEGO games mostly for that sort of effect - but the implications of its use are pretty horrific and it would absolutely lead to a deeply distressing death if left uncountered.
