Alrighty so it was a plan! Jacob cast the bubble head charm again and dove under. Jacob went on the command of the other ravvies. "Wingardium Leviosa" he said hoping, it would work. It had to work, cause that was their only plan, or they would have to do what everyone else was and just brutaly murder the box with so many random spells and no tactic. Thats not how Ravenclaw worked
