I understand you need to perceive a target to affect it, except with Intellego right?
So say I have a noisy animal, say a boar, rooting around in my garden.
I get up and look out, but I can't directly see it, I can hear it, smell it and I know where it is, say to within a half metre.
Can I affect it with a voice range spell?
Would it make a difference if I knew which bush it was in, by the shaking of the bush?
Say the same boar is trapped in a block of ice, but I can clearly see it through the ice, can I affect it with sight range?
