Spells to Resist Scrying, 30 Days of Magic

I think it is interesting to consider anti-scrying spells in Ars Magica. While there is not specific guideline, we do have examples from rulebooks that perform very similar tasks. The closest example is spells to prohibit teleportation spells (Impede the Impertinent Interloper (PeVi Gen), from Transforming Mythic Europe, p.109); see also a discussion on fooling Intellego magic on the Ars Magica forums, and a spell for an item written as part of a magical defence system (also a PeVi Gen spell).

The spells below are variants to prohibit scying – each of which use the Perdo Vim guideline for manupulating a specific type of magic, as “scrying spells”.

It’s worth pointing out that “Perdo Vim fields” are disliked by some gamers in the Ars broader community. Specifically the Target: Personal spells below are probably borderline – I understand and respect the view however it seems a very plausible use of magic.

Reduced Might Stripping, a House Rule for Ars Magica supernatural opponents

Aside

A great house rule to limit the impact of might stripping spell effects on supernatural creatures in Ars Magica – Multiple applications of Perdo Vim do not stack, specifically for reducing a creatures Might or affecting an Arcane Connection. Once damaged only a more powerful spell will inflict more damage. Makes the famailiars tougher too.

Found via a discord group I’ve been chatting to. Clever idea!

Lost Spells (part 15) to destroy vis

More lost spells from sources around the web which are updated for 5e Ars Magica. This spell destroys pawns of vis. I have to ask why a caster would do this (demonically tainted vis perhaps?), however it seems a legitimate use for Perdo Vim.

Burning Vis

Perdo Vim General, R: Voice, D: Momentary, T: Individual

Up to 1 pawn of Vis per 5 levels of this spell are destroyed.

(Base General, +2 Voice)
