So I say we change the rule. I say my power should be our power. From now on, every girl in the world who might be a Slayer… will be a Slayer. Every girl who could have the power… will have the power. Can stand up… will stand up. Slayers, every one of us. Make your choice. Are you ready to be strong?
Buffy Summers[src]

A spell continuously activated multiple Potential Slayers around the world, replacing the original Slayer line of Chosen Ones into a collective, shared power.[1] It was first performed by Willow Rosenberg in 2003 during the battle at the Hellmouth.[2]



In 2003, the First Evil taunted Buffy Summers that despite her efforts, she and the Scooby Gang would not fare well against the army of Turok-Hans. The First also taunted Buffy that she would die alone. Because of this, Buffy came to realize that she could change the rules so that she and Faith Lehane were not the only activated Slayers.[2]

Buffy then came up with a plan that would involve the witch Willow Rosenberg to tap into the essence of the mystical Slayer weapon , which was tied to the Slayer, and rewrite the set rule of the "Chosen One." This would activate Potential Slayers worldwide and overrule the Shadowmen's original magic.[2]

While Buffy led everyone into battle in the Hellmouth, Willow performed the ritual in the Principal's office of Sunnydale High School. She successfully channeled the power of the Slayer, allowing the Potentials to fight back against the First's army.[2]


After the spell's enactment, Buffy was able to find and organize willing Slayers into the Slayer Organization, which counted with 500 Slayer from the 1,800 active worldwide.[3]

Unknowingly though, by shifting the balance of power in the world so drastically, Buffy had proven herself as the Slayer spoken of in the Twilight prophecy, believed to be the "next step up the metaphysical ladder." With the prophecy set in motion, her reward for this would be to gain god-like superpowers, including increased strength, flight, and complete invulnerability; these powers would enable her to bring about Twilight and survive the resulting apocalypse.[4] She refused it, though,[5] and to prevent the impending apocalypse, Buffy broke the Seed of Wonder, causing the end of magic.[6]

Without a source of magic in the Earth's dimension, the Slayer activation chain was broken; previously activated Slayers though the spell retained their powers, but no more Potential Slayers were called without magic to continue the spell.[6]

The spell was reactivated when the new Seed of Wonder was spawned from its original caster, Willow, with the new rules of magic now declaring "No longer is but one chosen. The power itself becomes the chosen one… and the one who chooses." This implicated that the combined spiritual force of all past Slayers had then more agency than before, continuing the spell legacy of a collective, shared power.[1] One notable change from the original line was the acceptance of the honorary male Slayer, Billy Lane, by the spirit of the First Slayer.[7][1]

Prior to the timeline changes brought upon through the Reckoning,[8] the spell deteriorated to the point that no Potential Slayer was called until Melaka Fray in the 23rd century.[9]


Slayer spell

In a variant of the spell, Buffy and Willow return borrowed power.

To defeat the Pandora Project's leader, Joanna Wise, who had turned herself into a magic-infused cyborg much stronger than a Slayer, Buffy performed with Willow a spell to reverse the activation of the Potential Slayers they had done in 2003. Willow explained that Buffy had shared her power with all Potentials, which in turn had grown in each of them. Using the Scythe once again, Willow was able to put the grown powers of thousands of Slayers back in Buffy, greatly empowering her and giving her the ability to even cut magic with its blade.[10]

After defeating Wise and eventually healing herself, Buffy and Willow used the Scythe to return all the power, performing the spell once again.[11]

In the next year, to defeat an army of demons during the Reckoning, Willow and Buffy began to once again use the Scythe to combine the power of all the Slayers into Buffy. Although, this was interrupted when Harth Fray intercepted them with an original Shadowmen's staff and, interlocking it into the Scythe, channeled the power into himself.[12] The Slayer connection, though, was too much for a male to handle, and he was killed in this moment of vulnerability. His death allowed the power to flow from him back to its owners, including granting his sister her full powers. This new Reckoning changed the future into the collective Slayer line continuing up to the 23rd century.[8]


The spell required the Mʔ as a key instrument. While chanting surrounded by lit candles, Willow channeled her energy to the Scythe. After a few seconds, the weapon began to glow, and the spell took effect.[2]


I can feel them, Buffy. All over. Slayers are awakening everywhere.
―Willow Rosenberg[src]

The spell temporarily turned Willow's hair white, reflecting the good magic of the spell, in contrast to her past dark Willow persona while performing dark magic. Then, she dropped on the floor, exhausted, exclaiming in contentment: "Ha! That was nifty." As the Slayers were activated, they were able to feel to surge of power inside them, causing them to be initially confused, but otherwise more confident and connected.[2][13]

Another effect of the spell was that it allowed Willow to sense the Slayers being activated elsewhere, long after the spell has been completed.[2] Not all Potentials were instantly called, but caused them to become receive their true power upon reaching a certain age and maturity. This was notable with the Slayer Soledad, who was activated in her 15th birthday, two years after the spell was performed.[14]
