[mh] ritual path magic and creating illusions

[Merrick]

I'm trying to put together an illusion ritual for my monster hunter game and am having difficulty with how to stat it out. Specifically, I'm trying to do a "Mirror Image" spell (from d&d). Should it be based on the path of energy (greater create energy) utilizing sound and light to make an illusion or maybe the path of mind (greater control mind) to make people "think" they see something that isn't there?

If you have any advice please reply or feel free to PM.

Thanks,

Merrick
