You create an invisible sensor somewhere within the casting distance, which can be a place you are familiar with (a place you have visited or seen), or a conspicuous place you are not familiar with (for example, behind a door, Corner location or in the woods). The sensor stays there for the duration of the spell and cannot be attacked or interacted with.
Classes: Wizard, Bard, Sorcerer, Cleric
Casting Time: 10 minutes
Range: 1 mile
Components: V, S, M
Duration: Concentration, up to 10 minutes
When casting this spell, you can choose to observe or listen. You can sense the target space with the sensor in the selected sensory way. You can also switch between observation and listening with one action.
A creature that can see the sensor (such as when a creature has a gain such as seeinvisibility or real vision) will see that the detection point is a fist-sized semi-transparent sphere with a shimmering light.
