Haunted Grimoire (Spirit •••• + Prime •)
Practice: Patterning
Primary Factor: Potency
Cost: 1 Mana
Withstand: Total Arcanum dots used in the rote and Rank
Suggested Rote Skills: Crafts, Intimidation, Occult
The mage binds a spirit into a Grimoire, writing its Essence into the vessel’s Pattern. Unlike a fetish, a haunted Grimoire doesn’t host the spirit’s Numina or Influences, nor does it have an Essence pool. Instead, the spirit is a part of the words and runes themselves, trapped inside the Supernal symbols. The Grimoire gains the Resonant and Open Conditions for that spirit, which is a Lasting effect of the spell until resolved as usual.
Whenever someone casts a rote from the Grimoire, she automatically increases the rote’s primary factor by the spir- it’s Rank instead of by her own Arcanum rating minus one, but the spirit has the chance to escape by riding the vessel’s Mana out into the world. It rolls its Power + Finesse in a Clash of Wills against the caster. If the spirit succeeds, the spell ends, and the spirit is released into Twilight, although multiple spirits can be bound into a Grimoire with separate castings of this spell.
Whenever someone memorizes a rote from the Grimoire, the spirit has an opportunity to possess her, again rolling Power + Finesse in a Clash of Wills. The mage learns the rote regardless, but if the spirit succeeds, it transfers the Resonant and Open Conditions from the Grimoire to the mage and may immediately use the Possession Manifestation even if it normally couldn’t, at no Essence cost.
Casting this spell constitutes an Act of Hubris against Un- derstanding Wisdom.
Substitute Death ••••: The mage may bind a ghost into the Grimoire instead.
