Dominus Trinus is a spell located at the front of the Book of Shadows that was specifically created to unbind the powers of the Charmed Ones.


Unbinding the Charmed Ones' Powers[]

In late 1998, six months after the death of their grandmother, Prue, Piper, and Phoebe Halliwell were reunited in their family house, Halliwell Manor. When Phoebe returned from New York, she and Piper played around with a spirit board that belonged to their mother Patty.

Phoebe was known for pushing the pointer, but on that night, the pointer moved on its own and spelled out ATTIC. Prue believed it was just Phoebe doing it, but Piper had seen the pointer move by itself. Phoebe later went to the attic and the door magically opened after being sealed off for years. As she entered the attic, a light shone upon an old trunk. She opened the trunk and found the Book of Shadows.

When she opened the book, she read out this incantation, which caused a blue light to shine from the chandelier, the sisters in their photo moved closer to each other and unbound the powers of the Charmed Ones, as well as their collective power, the Power of Three.[1]

Telepathic Communication[]

When Piper became trapped in an alternate dimension and Paige became stuck in limbo, Phoebe wrote a variation of the Dominus Trinus in order to invoke The Power of One to telepathically communicate with them.[2]

Shift of Power[]

While Paige was on the verge of death, the Book of Shadows inadvertently cast this spell and shifted the bond of the Charmed Ones back to the original sisters. Due to Prue being the only candidate for the Power of Three to shift to, she became Charmed once again, albeit temporarily.[3]

Notes and Trivia[]

  • Dominus (pronounced Dom-e-noose) is Latin for "Master", Trinus (pronounced Tre-noose) is Latin for "Triple", "Three". The title refers to the three masters; the three Charmed Ones.
  • Seeing as Grams was the one who bound the sisters' powers, she may have created the spell to unbind them in case they ever were united after her death.
  • The page was seen again in "Valhalley of the Dolls, Part 1", although it was located in the middle of the book.
  • A scan of this page was included in the official Charmed Magazine.
  • A scan of the alternate version of the page was included in The Sourcebook. However, the actual page does not include "The Charmed Ones" part or the border.
  • This spell is similar to A Spell for Invoking the Power of Three, which the sisters used in "Witch Trial" to defeat Abraxas.
  • The first eight lines of the Dominus Trinus are taken from the Witches' Creed by the Wiccan High Priestess Doreen Valiente. In Charmed they used the first two lines of the first verse and the last two of the ninth verse, changing "wrought" with "sought".
  • The Latin American Spanish dub's incantation of this spell has become a viral meme on TikTok, often used in a ritual of some sorts.
