[quote=@Gliding Snake] Sight Trick - This rather simple spell forms a unique barrier around the caster. While it does not make them invisible, it can cause the minds of others to simply overlook the caster; they can see the caster, but they fail to truly notice them. It does not cloak sounds and smells, and those who are alert can usually see through it.[/quote]

You just made the magic version of a friggin Perception Filter didn't you?
