Maleficent's Staff

Maleficent's Staff is a magical golden scepter owned and wielded by the evil fairy Maleficent. It possesses great magical power that she uses for her evil purposes.

Sleeping Beauty
Maleficent appears with her staff and her pet raven, Diablo, during Aurora's christening when she interrupts the celebration. She uses it to perform her evil magic as she put a curse on Aurora, saying that before the sun sets on her 16th birthday, she shall prick her finger on the spindle of a spinning wheel and die. When King Stefan and his wife, Queen Leah orders their guards to arrest her, she uses her power and that of the staff to flee with Diablo. It is later used to punish her goons back at her castle in the Forbidden Mountain for failing to find Aurora. (They had been searching in cradles for sixteen years.)

On the eve of Aurora's 16th birthday and back at her parents' castle, the staff is used to transform Maleficent into a will-o'-the-wisp, hypnotizing Aurora before luring her to a remote tower, where Maleficent transforms into the spinning wheel on which Aurora pricks her finger to fulfill the curse.

After Diablo is turned to stone by the Three Good Fairies during their escape from Maleficent's castle, she uses the staff to summon lightning bolts and spells aimed at Prince Phillip in order to hinder him, including a "forest of thorns", which she conjures by chanting a spell using the immensely powerful dark magic of the crystal orb on it:

"A forest of thorns shall be his tomb! Bourne through the skies on a fog of doom! Now go with the curse, and serve me well! Round King Stefan's castle, cast my spell!"

Prince Phillip is able to overcome the mystical thorns, so Maleficent takes her staff and leaves her castle to personally deal with him by transporting herself in front of King Stephan’s' castle, blocking his entry. She then tells him that he shall have to fight her, and "all the powers of Hell" and transforms into a huge dark dragon. Though she overwhelms him, and it looks like he is about to meet his death. The Three Good Fairies transfer some of their power to his sword with this incantation:

"Thou sword of truth, fly swift and sure, that evil die and good endure!"

And so he throws the enchanted weapon into her heart, fatally wounding her. As she falls forward, she attempts to devour him, but misses, and her heavy weight causes the cliff beneath her to crumble, and she falls to her death. The staff is nowhere to be seen, and all that's left is her shredded robe, with the sword still stuck in it which blackens.

Maleficent
After Maleficent had her wings cut off by King Stefan, their absence made it difficult to balance. She creates the staff from a simple twig to help her walk, and later carries it to signify her position. Even when she regains her wings, she still wields it.
