Tuatha's Grimoire



Tuatha, being a powerful evil witch, owned her own Grimoire which she had found hidden under a rock in the cave she had been entombed in, presumably have been put there before her containment and left for the 200 years she was imprisoned.

Just like the Halliwell's Book of Shadows it is known to contain spells and potions recipes although given its size and status (or lack thereof) compared to the Charmed BOS it can be safely assumed it is not as comprehenisve.

Powers & Abilites
Although the warlock who owned the book was even stronger than The Charmed Ones her Grimoire is not thought to have any special tricks such as the power of the Grimoire and The Book of Shadows to protect themselves rom good and evil respectively. However, on balance it did survive until a rock for 200 hundred years with no visible signs damp, moss, of attempted digestion by animals or breakdown of any kind so maybe its only power is preservation.

Spells
In the epsisode it debuts, Tuatha's Grimoire introduces the audience to the "To Disempower A Witch" spell which takes away not only a beings magical powers but also basic ones like scrying, potion making and Spellcasting:

''Within the passing of this hour Take away all their/her/his powers''


 * Requires a Human Heart, one for each being to be dismepowered.
