Ars Magica Digital Codex

Wizard's War Tunnel Effects

These effects are designed to be cast through Intangible Tunnel-style effects. They are grouped according to magnitude. As these effects are low magnitude, a magus may be tempted to attempt these effects as spontaneous spells. However, if the target has a Magic Resistance (as most magi do, due to the Parma Magica) then the caster will be able to Penetrate much more easily with a formulaic effect.

A character truly proficient at Wizard's War would likely learn several of these effects. This is because many magi are unusually resilient against particular Forms (due to both the Form bonus to Magic Resistance and special Virtues, such as Immunity). Spell masteries, such as Multiple Casting and Penetration (see ArM5, page 87), can make some of these spells delivered via Intangible Tunnels much more effective.

If a character has a high Parma Magica (or is sheltering within a high-level Aegis of the Hearth), then it may only be possible to affect him with the lowest-level effects. One possible strategy is to use low-level effects, such as the Chill Touch of Exposure, to render the magus unconscious. He can then be easily dispatched with mundane means, such as a knife to the back.
