Illusory Animation

Through various illusory elements you create an area of magical counter-surveillance. When casting this spell, you must give a general description of what will be shown or hidden. If there is a routine you want displayed, you must describe it, but it will never have any perceptible flaws. Once the Illusory Animation is established, it can’t be changed.

Magical attempts to observe the area automatically detect what you established as the Illusory Animation. You could, for example, camp in a region and protect it so that, when seen or heard magically, it shows no trace or evidence that anyone has been (or is) there.

If someone tries to observe that location physically, the illusion holds, but if something is very different from reality and gives reason for suspicion, a Wisdom saving throw can be made to recognize it as an illusion — though this doesn’t dispel the illusion.
