Tracer

You touch a creature or an object and mark it for the duration of the spell.  While it is marked, you know exactly the direction and the distance that separates the target from you.

At Higher Level.  When you cast this spell using a spell slot of 2nd or 3rd level, the duration of the spell becomes 8 hours, and for the duration, you can hear sounds around the target as if you were on the target's space in addition to the other effects of the spell.  When you use a spell slot of 4th level or higher, the duration becomes 24 hours and you can see things around the target as if you were on the target's space (the image of the target's surroundings appear like a small illusion that hovers over your hand).  You can't benefit from darkvision, blindsight, tremorsense, or devil sight when you look through the image created by that spell.
