Priori Incantatem, also known as the Reverse Spell, is a magical spell in the Harry Potter universe that reveals the most recent activity of a wizard's wand.
The Reverse Spell (Priori Incantatem) is a magical phenomenon that can occur when two wands which share the same source for their cores are forced to compete in combat. It is sometimes referred to as the "reverse-spell effect". It can also be induced by analytical spells, like an extension of the Prior Incantato spell.
The spell is known as Priori Incantatem, where a wand forces another wand to reveal the spells of its past. Lord Voldemort's wand history was simple; he was out there to kill as many as possible, with seemingly no remorse.
The Eradication Spell (Deletrius) was a charm that could disintegrate certain objects and served as the counter-charm to the Reverse Spell, vanishing the shadow emitted from the wand.
The Hardening Charm, also known as Duro, is a light, offensive incarceration spell, which petrifies the victim in stone for a short time. They will be unable to move or cast. However, the chat will not be disabled, nor will their ability to equip and unequip their wand.

Therefore, figuring out a spell that is Draco's favorite is hard and, in the movies, there is no defining moment that cements a spell as his favorite. Based on Harry Potter lore, and an article by The Healthy Journal, Draco's signature spell is a N.E.W.T standard spell, The Protean Charm.
Diffindo is a damage spell that allows players to slash objects and enemies from a distance in Hogwarts Legacy.
Salvio hexia is a defensive spell which deflects hexes from the enchanted area. Though the spell has been used widely throughout the centuries, it's origin is still a mystery. Thanks to generous donations, however, we do know that the spell dates back to at least the 17th century.
Rictusempra, the Perpetual Tickling charm, which apparently can be stopped by the Finite Incantatem charm, was used by Harry against Malfoy in the Duelling Club. The intent was, of course, to tickle Malfoy to the point that he would be unable to jinx Harry in return.
Avada Kedavra
Topping the list for the most powerful spells in the Harry Potter universe is no other than Avada Kedavra, Voldemort's favorite to instill his will and fear onto others. The spell itself is a play on Abra Kadabra and is easy to cast by just about anyone in the Wizarding World.
Avada Kedavra
It's used to kill people, it's an Unforgivable Curse, and it was Voldemort's favourite, so it's going last.
Avada Kedavra has only one purpose: to kill. However, it's not the only curse that can be lethal. Stunners can be lethal, for instance — particularly if someone takes multiple stunners or one is a direct hit over the heart.
The Avada Kedavra – the killing curse from the Harry Potter Wizarding World is unforgivable, cannot be blocked, and is colored green.

It's just a stupid nickname given by two bully friends James and Sirius. Instead of Severus Snape they call him Snivellus Snape.
Hermione's bluebell flames
This spell becomes one of Hermione's trademarks. We don't hear the incantation for it in Philosopher's Stone, but it could be a variation on Incendio. Hermione first uses it against Snape when she and Ron think he is cursing Harry's broom in his first Quidditch match.
Extended Description. The Nox spell is used by Harry and Hermione in Harry Potter and the Prisoner of Azkaban, and in the depths of Gringotts in Harry Potter and the Deathly Hallows, to extinguish their wands, previously illuminated by means of the Lumos charm, when they no longer needed their light.
Hermione cast a bluebell flame that could be carried around in a jar. She used it to set Snape's robes on fire during the match between Gryffindor and Slytherin of her first year. Hermione used this spell against Devil's Snare when she, Harry, and Ron worked through the challenges surrounding the Philosopher's Stone.
