What is the Curse of Faithfulness in Harry Potter?

Used to protect a secret.

Once the Loyalty Charm is in effect, the secret will not be revealed unless the secret is revealed by the Secret Keeper himself. That is, no one other than the secret can reveal the secret (so Snape cannot reveal the location of the Order of the Phoenix to Voldemort).But if the secret keeper reveals the secret to someone else (as Wormtail did to Voldemort), then the protection of the secret will be breached.

If the secret dies (as Dumbledore did), then all who know the secret becomes its secret keeper.

The Loyalty Spell can be broken if the Secret is weaker than the Cracker.

The Loyalty Charm is a spell in the Harry Potter series that was used by the Potters to protect their home, but was eventually betrayed.

This spell relies on a secret keeper to keep a secret. If the person who keeps it secret doesn't tell it, then the secret will never be known to others. Confidentiality can be one or more than one.

When the previous secret person dies, the secret keeper who has a brave loyalty spell will become everyone who knew the secret, and the probability of being cracked will be greatly increased.

This spell is used to protect secrets. That is, you can find someone you trust very much and cast this spell on him, so as long as this person doesn't tell it, the secret won't be known to anyone, but once the person dies, then everyone who knows the secret will become a secret.

[Unbreakable Curse]: Used for an oath between 2 people.

And another person needs to be the executor.

Breaking the spell will result in death.

Courageous Loyalty Mantra: Used to keep something or something secret.

and there must be a confidential person.

It is generally more than one confidential person.

Confidential: The executor of the mantra of faithfulness.

Literally, it means a person who protects a secret.

This spell is to establish the secret of something or something on one or more people.

Since the role of guarding secrets.

Once this spell is active.

In the event that the confidential person did not divulge this secret.

This secret can be completely protected.

It can effectively prevent the invasion of others.

Here's the difference between the two.

Unbreakable spells are spells that must be completed once they have been made.

It cannot be violated. Once violated, there is only a dead end.

But the Loyalty Mantra is different.

But the requirements for the spell bearer are high.

This mantra must never be broken (and of course it will not die).

But a little leaked secret.

The curse of loyalty will be self-defeating.

It's like Ha7 when he returned to Grimmauld from the Ministry of Magic and accidentally brought in the Death Eaters.

This divulges a secret to a certain extent.

And so the spell was broken.

But Hek didn't die.

That's the difference)

And the Unbreakable Spell is unbreakable.

Literally understandable.

Once the spell is complete.

Unless the task is completed.

Otherwise, you will die (except in the case of death other than the appointee, of course) [Curse of Faithful Courage] can be broken.

However, it will take some time.

It also depends on the degree of loyalty of the person who kept it secret.

If it's better to die than give in.

Then there is no way.

If you meet someone like Monton.

Only consider yourself unlucky.

And if the [Courageous Loyalty Mantra] had only one secret person in the first place.

Someone else knew the secret under the leadership of this secret man.

Then this person also became a secret.

For example, the mad-eye man of Harry 5 takes Harry to Grimaud.

Harry didn't know.

But after reading the text.

He also became a secretist.

Because he knew the secret from then on.

Later, Deng died.

Harry and the others naturally became secretives.

But the Unbreakable Curse is different.

It's just one-to-one.

Even if a third person knows.

To no avail.

Tasks are still to be completed by the appointee.

Hope it helps you somewhat.

He became the secret keeper of the Order of the Phoenix, and no one else could know about it unless he told the location himself, and the Dementor Mind was invalid.

The spell in the Harry Potter series is an extremely complex spell that uses magic to hide someone's secret forever in the soul of a living person. The secret is hidden in the heart of the chosen person, the person who keeps it secret, and therefore it will never be discovered, of course, unless the person who keeps it out of his own accord. As long as the secret keeper doesn't reveal it, even if the thief sticks his nose to the glass of their living room, they won't be seen.

Harry Potter and the Prisoner of Azkaban first appears, chapter 10, page 118.
