In Fantastic Beasts and Where to Find Them, what spell did the MACUSA Aurors use to destroy the Obscurus?
It seems to be a wide array of offensive spells. No specific ones are mentioned in the screenplay.
SCENE 116 - INT. SUBWAY—NIGHT
Aurors continue to aim spells at the Obscurus, their efforts unrelenting and brutal.
Under this pressure, the Obscurus finally seems to implode – a white ball of magical light taking over from the black mass.
The force of the change sends TINA, NEWT and the Aurors stumbling backwards.
