These spells demonstrate remakes of Opening the Intangible Tunnel (ReVi Gen, ArM, p.162) to instead include a visual representation of the tunnel which makes using one far easier for other Magi. There is also a variation on OtIT for Group targets.
Aside – I wasn’t sure if these spells needed either (a) a method to detect the tunnels within the spell, or (b) can actually create a visual guide for an intangible thing. I’m sure that Imaginem does not need a requisite for the material it is changing or creating an image upon, as there are many sample spells which do this in Ars RAW and none use requisites for the spells. That said the consensus in the official Ars Magica forums indicated that without requisites the spells just wouldn’t work. Ah well.
Opening the Illustrated Tunnel
Rego Vim / Imaginem Gen, R: Arcane Connection, D: Concentration, T: Individual
This spell opens a magical tunnel between the caster and the target (identical to the spell Opening the Intangible Tunnel) except the the caster’s endpoint of the tunnel is clearly visually represented as a swirling vortex styled by the casters sigil.
Spells cast through this tunnel must be at least one magnitude less than the level of this spell.
(Base Gen, +4 Arc, +1 Conc, +1 Im sub effect)
The spell below is used to allow others to target the end of a detected Intangible Tunnel style spell, for better cooperation between Magi. It could also use R:Touch to make the spell easier to learn and cast.
Illustrating the Intangible Tunnel
Creo Imaginem / Vim 10, R: Voice, D: Sun, T: Individual
This spell creates a visual representation upon an Intangible Tunnel. The caster must already be aware of the particular endpoint of the tunnel to create this illusion, either discovered by another means, or because they were the caster of the tunnel spell. The Vim requisite anchors the illusion to the tunnel.
Typically the tunnel illustration is visually styled from the casters sigil, or rarely this spell designed to be presented to another sense.
(Base 1, +1 Moves with the tunnel’s endpoint, +2 Voice, +2 Sun)
