Suppressing the magic of others, a meta-magic question for Ars Magica

An aside I pondered a while ago – how hard is it to suppress the magic of others?

The effect from the core rulebook called Suppressing the Wizard’s Handiwork uses the Rego Vim guideline for a caster’s own spells and lasts only while the caster concentrates. It is an excellent example of a core spell designed to inspire variations. From that inspiration, here is a variant designed to suspend the spells of others.

Suppressing the Conjurer’s Incantation

Rego Vim (Gen), R: Voice, D: Concentration, T: Ind

Suspends a spell cast by another, less than or equal to Half (Vim spell level -1 magnitude) of this spell.

(Base to suppress spells cast by another, equal to half (level +5 mag) of the Vim spell, +2 R to Voice)

It illustrates that suspending the spells of others is very difficult, even more so if this effect was redesigned to extend to Sun duration; effectively suspending effects of less than or equal to half of (level -3 mags). Meaning the spell must be at level 25 and will only neutralise spells of level 5 or less – not worth it at all when compared to how easily a Wind of Mundane Silence can remove effects.

As with many things, it is easier to destroy than change or maintain. Interesting.
