Manipulating non-concentration spells after casting them

Personally, I'd make the intangible tunnel require "group" target, as it's linking two things other than the item itself.

So, I went back and researched this - and yep, according to both AM5th and HP, if you're not the caster you do need some sort of supernatural way to sense the tunnel if you want to use it (Just Per+Magic Theory doesn't cut it) - however, both writeups are also clear that anyone who can perceive the tunnel can use it to cast, in either direction. So I don't think there would be any need for any additional modifications.

For some reason I thought it required a minimum of voice range to cast through a tunnel that didn't target you; but clearly I was mistaken having checked it just requires the range between you and the target.
