Detect Gaze

For the duration, you can sense if a creature is looking directly at you, or at your reflection.If a creature directly looks at you and observes you, you also feel their direction from you. You can detect any number of creatures this way.  If a creature detects your presence with any of it's natural senses, you feel a small, tingleing sensation, but you gain no information on how many, or where they are. If the creature can detect you, but isn't paying any attention to you (for example if you are in a large crowd), you can't feel them with this spell.

Constructs; and creatures who are detecting you trough magical means, or are immune to charming are immune to this spell and can't be detected by it.
