1. Expecto Patronum
Expecto Patronum or the Patronus Charm is a mystical and ancient form of magic. Quoted from the opening of the Spell Book (Miranda Goshawk), it 'summons the magical guardian of positive feelings'. This is the most powerful spell described in Harry Potter, capable of warding off Dementors. It summons a powerful guardian force from within, manifested as a creature made of light.
The Patronus of each wizard, witch often differs but always appears under the guise of an animal that the wizard, witch shares a deep affinity with. (Although, in some special cases, the Patronus can still change its form). The important thing is that the Patronus created can be used in many ways: to deliver messages, repel Dementors, and sometimes just to create a warm, safe feeling for the summoner. However, this spell is very difficult to perform. When failed, the Patronus appears in an imperfect form, possibly just a shadow or a faint light.

The Enchantment of Repelling Foes is a potent spell useful in thwarting strangers from infiltrating Hogwarts or preventing prisoners from escaping Azkaban,... It can create an invisible shield, deflecting curses and shielding physical entities, often used to protect a person or a specific area.
When curses strike the magical shield from the powerful Protecting Charm, they can be rebounded straight back at the opponent, and in some cases, even blasted in various directions or dispersed upon touching the surface of the shield. The Protecting Charm is a rather difficult spell to perform.
The Protecting Charm was seen only once throughout the 8 Harry Potter films: when Voldemort and his followers were about to attack Hogwarts and the professors unitedly raised their wands skyward, forming a protective barrier around the school. However, this charm can be easily broken if attacked by a force stronger than it. Hence, it does not provide complete and enduring protection and can leave those facing danger vulnerable in an instant.Fiendfyre, also known as cursed fire, imbues flames with consciousness, making them sentient and ready to hunt any prey. The fire is one of the products of dark magic. Fire, already highly dangerous in its normal state, becomes even more terrifying once cursed and imbued with consciousness, ready to hunt you down just like the Raptors in Jurassic Park. And Crabbe, the character who unleashed that inferno in Harry Potter and the Deathly Hallows Part 2, even fell victim to the very flames he conjured. Besides killing, the fire also has the ability to destroy the Room of Requirement.
You may have witnessed this curse in Harry Potter and the Deathly Hallows Part 2 when Harry, Ron, and Hermione were nearly killed by it in the Room of Requirement. The fire is one of the products of dark magic and was created in the film by Gregory Goyle, a character notorious for his dim-wittedness and mischief, to the extent that he even fell victim to the very flames he conjured. There is a way to extinguish Fiendfyre, however, very few possess the ability to do so, and the only practical effect of this curse is its capability to destroy the Room of Requirement.
Fiendfyre by CrabbeExpelliarmus is the quintessential spell of Harry Potter. While it may not inflict significant harm, it serves to disarm the opponent by removing their wand - the primary weapon. Harry used it in the final battle at Hogwarts, and everyone witnessed how this spell helped the forces of good emerge victorious.
No one knows exactly when the Disarming Charm was first created; many wizard historians speculate that the great Merlin himself invented this spell, while others theorize it was developed and widely used in Madagascar in the 11th century. Regardless of the origin, the Disarming Charm did not become widespread until 1379 when Elizabeth Smudgling — a talented charm inventor under the tutelage of Miranda Goshawk — used it in a doubles match in Dartmoor.
The Disarming Charm emits a burst of red light, a distinctive feature that can be observed before its effect is realized. The brightness of this burst varies depending on the magical prowess of the caster; the most powerful Disarming Charms emit a dazzling red light. Another notable aspect of the Disarming Charm is that if multiple individuals cast it simultaneously, its effectiveness is greatly amplified, not only disarming but also capable of subduing opponents.
