Here are some spells based upon Snow White (as best as I can fit them) for Ars Magica. Some of the magical effect from the story are detailed in the core rules; such illusions, transformation, scrying, and forms of divination.
The Queen’s poisoned apple could be written many ways. A straight wounding poison, an extended sleep spell, and a faerie sleep spell. The trick with hermetic magic is to create a poison which knocks the target unconscious rather than wounding them. A Creo spell shouldn’t be able to replace the process for creating potions although by creating specific poisons within another substance is a work around. YSMV. My thought is that a toxin can wound, fatigue, sleep, or other effect; and the trick is really getting the target to eat it.
This means proposing a new Creo Aquam guideline for a fatiguing toxin instead of a wounding one. Not a huge leap.
- Creo Aquam Guideline: Base 5, to inflict 1 level of fatigue if a Stamina check is failed against a difficulty of 3.
- Each magnitude adds an additional fatigue level. Optionally each magnitude also increases the difficulty check by 3.
Draft of Weariness
Creo Aquam 20, R: Touch, D: Sun, T: Individual
The draft of toxin conjured inflicts a fatigue level if the imbiber fails a Stamina check vs 3.
(Base 5, +1 Touch, +2 Sun)
Which means a low powered spell matching the poison-apple using fatigue would be as below, noting that the higher of the two base effects is chosen; Base 1 CrHe to create a fruit, and Base 5 for the poison.
Fruit Created for Suffering
Creo Herbam / Aquam 20, R: Touch, D: Sun, T: Individual
The food conjured is tainted with a powerful magical toxin which inflicts a fatigue level on anyone who eats it if they fail a Stamina check vs 3. The spell may create a single discrete item of unprocessed food, such as fruits.
(Base 5, +1 Touch, +2 Sun, Herbam requisite free)
Fruit Imbued with Suffering
Muto Herbam / Aquam 20, R: Touch, D: Sun, T: Individual
The targeted food is tainted with a powerful magical toxin which inflicts a fatigue level on anyone who eats it if they fail a Stamina check vs 3. The taint becomes harmless when the spell expires.
(Base 5, +1 Touch, +2 Sun, Aquam requisite free)
The base for altering Herbam is MuHe3 however as the base for the toxin was CrAq5 that was used, which rationalised the free Aq requisite.
