Specialised versions of Opening the Intangible Tunnel

I’ve been re-reading the Ars Magazine Sub Rosa recently and came across a spell concept that I really liked – versions of Opening the Intangible Tunnel which limit the type of magic which can be cast through them (see Sub Rosa #13, p.97).┬áTypes might include spirit magic (as in the Sub Rosa article), or teleportation magic, or a type linked to one of the fifteen Hermetic arts such as Intellego.

This would make the tunnels useful for Magi with major specialisations, as Spells cast back through the tunnels might be limited to types where the target is not as strong, where the initial caster is much stronger, and where the target of the Specialised tunnel has no idea what the sub-type is.

It’s sneaky and very tactical. Great stuff.┬áHere is aversion for Scrying with Intellego, and a version for cold themed spells.
