As part of a November 2017 Ars Magica writing challenge – I’m doing one spell a day.
This post is a convoluted mix of ideas around Muto Vim meta-magic borne out into potential spell mechanics. Many of the points will only suit some players, and this is meant more as a discussion and example for MuVi in Ars Magica, rather than concrete assured spells for immediate use in a saga.
Many of the published MuVi spells are invented at Range: voice with the intent of casting against others or to assist others, there are many other permutations. The MuVi guidelines also indicate that a spell which modifies another by more than two magnitudes is possible but needs either Creo or Perdo requisites to add or subtract the magical power, and a Base level to totally change a spell is equal to or less than (half level +1 mag). It is interesting that the guidelines indicate adding a requisite Creo or Perdo, rather than plainly insisting the spell isn’t possible.
Here are samples I can see as useful MuVi modifications of Wizard’s Reach (Ars p.160) which steps the range in different ways, which demonstrates how the difficulty in MuVi spells increases dramatically.
Wizard’s Reach “Downward” for lowering the target range instead of increasing because canonical Ars Magica spell guidelines require very specific effects for Muto Vim. This might be desirable to work around the MR of an opposing caster from Range: Touch to Range: Personal. “Across the Span” for effects moving upward by 2 magnitudes, and “To Distant Shore” for an extreme example of spell extensions to a range, e.g. Personal to Sight, or Touch to Arcane. There is also the potential for the caster to affect their own spells rather than intend to work cooperatively, which are slightly easier due to one less in-built magnitude, indicated by “Sorcerer” to separate the effects.
Wizard’s Reach (Form) Downward
Muto Vim Gen, R: Voice, D: Momentary, T: Individual
This spell alters the targeted spell by reducing the Target range by one magnitude less, with the same limitations of Wizard’s Reach (Ars p.160). The target spell must be no higher than (level -5) of this spell.
(Base Gen, +2 Voice)
