My question is, at the end of the movie Grindelwald tries to escape, but Newt uses his Swooping Evil and another creature to secure Grindelwald. What was used to actually tie him up (the brown-gold crystallish looking thing)?


The screenplay says it’s “a crackling rope of supernatural light”.

In the screenplay of the movie that was released along with it, the effect of the spell Newt uses is described as “a crackling rope of supernatural light”. No spell name or incantation is given.

“In a split-second NEWT pulls the cocoon from his pocket and releases it at GRAVES. The Swooping Evil soars around him, shielding NEWT and the Aurors from GRAVES’S spells, and giving NEWT time to raise his wand.

With a sense that he’s been holding this one back, he slashes it through the air: out flies a crackling rope of supernatural light that wraps itself around GRAVES like a whip. GRAVES tries to hold it off as it tightens but staggers, struggles and falls to his knees, dropping his wand.”

The spell that seems most similar to this one, and that it’s most likely to be if it’s a spell seen already in the series, is the unnamed and nonverbally cast spell that Dumbledore cast against the Dark Lord when they were dueling in the Ministry. It’s described as flame, not light, and it’s unclear what its intended function is, but it seems the closest of the spells we’ve seen.

“This time it was the one-armed centaur, galloping in front of Dumbledore, that took the blast and shattered into a hundred pieces, but before the fragments had even hit the floor, Dumbledore had drawn back his wand and waved it as though brandishing a whip. A long thin flame flew from the tip; it wrapped itself around Voldemort, shield and all.”

It’s also possibly Incarcerous, which conjures rope. It’s used to capture people and tie them up, like Newt had done with Graves. However, when its effect is described, this spell doesn’t seem to conjure ropes of light.

“Be quiet!’ shouted Hermione, but it was too late: Umbridge pointed her wand at Magorian and screamed, ‘Incarcerous!’

Ropes flew out of midair like thick snakes, wrapping themselves tightly around the centaur’s torso and trapping his arms: he gave a cry of rage and reared on to his hind legs, attempting to free himself, while the other centaurs charged.”
- Harry Potter and the Order of the Phoenix, Chapter 33 (Fight and Flight)

The ropes conjured by “Incarcerous” are regular ropes, not ropes made of light, so it seems unlikely to be this. However, it still seems worth mentioning, since it’s similar in effect, though not appearance.

Eddie Redmayne says a magical lasso Dumbledore won’t think of.

When Eddie Redmayne mentioned what Newt used to tie up Grindelwald in the context of Newt’s specific skill set, he calls it a magical lasso, and says Dumbledore wouldn’t have thought to use it.

Eddie: I think that what I love about Newt is that he’s not the greatest wizard in the world, but his skill set is so specific. I mean, Tina and Newt call Grindelwald at the end of the last film using a distraction technique – had to see this one – and the sort of lasso [pronounced “lay-sew”] that Dumbledore wouldn’t have thought to use.

Katherine: That’s lasso [pronounced “lah-so”] in our country.

[Everyone laughs]

Eddie: Magical lasso. [laughs]

He doesn’t say what spell it is specifically, but since he considers it part of Newt’s specific skill set that he’d think to use it, and Dumbledore wouldn’t, it may be intended for use on magical creatures.

  • It's the Americanized version of Incarcerous. I tried to spell it without the "u" but it looked wrong. – Verdan Jun 23 '18 at 21:52

    Hey there. Would you by any chance have a clip of that spell (maybe from Youtube or stuff?) that you could edit in, to depict how it's similar? – Jenayah Nov 13 '18 at 23:01

From what I saw of the scene, the "ropes" looked a lot like the kelp you'd find in the ocean. It could be (a nonverbal) "Incarcerous" for all three examples but maybe the spell appears differently depending on who casts it? Standard rope for the average witch and wizard but if powerful enough, the kind of magic one has affects it too, so flame for Dumbledore and Newt - with all his travelling and adventures - something he would've seen while working with creatures.
