So no problem, all we need is combo Buffy; her with Slayer strength, Giles' multi-lingual know how, and Willow's witchy power.

The enjoining spell was a spell performed in order to combine the essences and abilities of several individuals into a vessel.[1]


In 2000, the core four members of the Scooby GangBuffy, Xander, Willow, and Giles — called upon the spirit of Sineya, the First Slayer, and performed the enjoining spell in an attempt to defeat the bio-mechanical demonoid Adam.[1]

During their previous planning, Willow wanted to cast a spell on Adam, but only Giles knew how to pronounce the spell's wording correctly. Xander then unwittingly inspired the use of the enjoining spell by suggesting that they needed to combine their respective talents into one, causing Giles to remember that such a ritual existed.[1]

The four performed the enjoining spell at the underground Initiative facilities. Willow acted as the spirit, Xander as the heart, Giles as the mind, and Buffy as the hand. When the spell began to take effect, the first three had their bodies immobile in trance, while the voices of all four spoke through Buffy's body. The resulting abilities were far superior than Adam's, so the Scoobies were able to successfully remove his power source, the uranium 235 core, and defeat the creature.[1]

The enjoining spell required the use of Tarot cards, lit candles, and a magic gourd. Sitting in a circle, the invoking of Sineya began:[1]

"The power of the Slayer and all who wield it. Last to ancient first, we invoke thee. Grant us thy domain and primal strength. Accept us and the power we possess. Make us mind and heart and spirit enjoined. Let the hand encompass us. Do thy will. By the generous will of the Ancients, the almighty power of the Divine Spirits... Your supplicants humbly beseech thee to behold us, and that which we possess... The moieties of the One, the Avatar... Spiritus... spirit. Animus... heart. Sophus... mind. And Manus... the hand. We enjoin that we may inhabit the vessel, the hand... Daughter of Sineya... First of the ones... We implore thee: admit us. Bring us to the vessel! Take us now! We are heart... We are mind... We are spirit... From the raging storm... We bring the power of the Primeval One..."


After Buffy's essence became one with those of her friends' through the enjoining spell, she gained the powers of:

  • Spell casting: Buffy had the ability to cast powerful magic spells, which she used to negate Adam's attacks and ultimately destroy his radioactive uranium power core. Examples of other abilities she derived from this power were:
    • Force field generation: Through a Sumerian defense spell, Buffy was able to access the ability of projecting a powerful field of manipulated energy, conjuring a barrier to block Adam's bullets.[1]
    • Transmogrification: Through a Sumerian transmogrification spell, Buffy was able to access the ability of transforming objects — she transformed one of Adam's rockets into three doves.[1]
    • Vanishing: Through an unknown Sumerian spell, Buffy was able to access the ability of making objects vanish, which she used to destroy Adam's power core — it immersed in white light and disappeared.[1]
  • Technology manipulation: Buffy had the ability to manipulate technology and technological constructs. With a wave of her hand, she caused Adam's weapon arm to morph back into a regular demon arm.[1]
  • Enhanced Slayer attributes: Buffy's Slayer strength, speed, and reflexes were dramatically enhanced, enabling her to best Adam in a physical fight and ultimately back him into a corner. She was even able to literally rip out his power core, killing him.[1]
  • Telekinesis: Buffy had the ability to make objects fly into the air, as seen by how she made Adam's power core hover into the air before destroying it.[1]
  • Fluency in Sumerian: All the magic spells Buffy employed in her fight against Adam were shown to be spoken through this language.[1]

In this empowered state, when Buffy spoke, so would Willow, Xander, and Giles. When Buffy managed to destroy Adam's power core, the enjoining spell faded abruptly, leaving her and her friends briefly drained of strength.[1]


Somehow our joining with Buffy and invoking the essence of the Slayer's power was an affront to the source of that power.

The enjoining spell had notable after effects. A Slayer calling on her friends to aid her in battle offended the spirit of the First Slayer, who believed that the Slayer should work alone with no connection to humanity. She proceeded to invade the dreams of the Scooby Gang, and began her attempt to kill them as punishment. Buffy eventually put a stop to her by rejecting her conditions, so they all wake up.[2]

Behind the scenes[]

  • According to The Official Grimoire, all the spells Buffy used against Adam were variations on an ancient Sumerian spell of peaceful resistance that invoked Enlil, the King of the Gods, who was said to have given humanity all the spells that both good and evil spirits must obey.
