True Sight Spell?

So, attacking the visible image probably misses, but people can still easily see that you're present, what you're doing (casting a spell, Body Language, etc), as you're not invisible.

Tell Position is practically custom-made for detecting visual displacement, as it tells you exactly where something really is relative to you. Know True Shape includes appearance-altering illusions, not just Shapeshift.

Aura might create the aura around the subject's true position, rather than being displaced.
