Triwizard Tournament
During the Second Task of the Triwizard Tournament, Fleur Delacour used the Bubble-Head Charm to breathe underwater in the Black Lake. While effective, it proved less efficient than Gillyweed or Transfiguring into a shark.
📚 Educational Decree #24
During Dolores Umbridge's time at Hogwarts, many students used the Bubble-Head Charm to avoid the stench from the Weasleys' Portable Swamp in the corridor. This became so common that Umbridge attempted to ban the spell.
⚔️ Limitations
The charm has some restrictions:
