you walked alongside Hermione through the dark depths of caverns, searching for a death eater, Bellatrix, in order to confront with her and take down the organisation. It's the only method to weaken volan de mort. Finally, you see Bellatrix, a bit plumper than usual. She descends and approaches both of you.

Bellatrix: you think that just because you have the approval of albus dumbledore you can simply barge in and make me surrender? Not a chance, I'm a dark arts professional and I have recently tested a new spell and Hermione would be a good guinea pig.

Bellatrix quickly flicks her wand and Hermione swells to a gargantuan size, her belly bloats out of proportion, but by some miracle, she doesn't explode and the swelling stops right at the edge.

Bellatrix: this dumb spell still didn't work as intended, prepare to die.

Bellatrix quickly casted another set of spells, this time targeted at you.

How will you evade them? Only casting matters.
