Clairvoyance

Divination
Level: 3rd-level
Casting Time: 10 minutes
Range: 1 mile
Duration: Up to 10 minutes
Components: V, S, M
Materials: A focus worth at least 100gp, either a jeweled horn for hearing or a glass eye for seeing.

You create an invisible sensor within range in a location familiar to you (a place you have visited or seen before) or in an obvious location that is unfamiliar to you (such as behind a door, around a corner, or in a grove of trees). The sensor remains in place for the duration, and it can't be attacked or otherwise interacted with. When you cast the spell, you choose seeing or hearing. You can use the chosen sense through the sensor as if you were in its space. As your action, you can switch between seeing and hearing. A creature that can see the sensor (such as a creature benefiting from see invisibility or truesight) sees a luminous, intangible orb about the size of your fist.

Player Guide

Use Clairvoyance before combat to scout enemy positions, numbers, and tactics—position yourself safely while gathering intelligence. Place the sensor in hallways, around corners, or in enemy strongholds to maintain awareness without risk. This spell is invaluable for planning ambushes, avoiding traps, or confirming whether a location is abandoned before committing resources. Remember that the sensor lasts for 10 minutes and requires concentration, so commit to one location and extract maximum information.

DM Tips

Clairvoyance is powerful for breaking the fog of war—consider what enemies might do to counter it (scrying wards, blind spots, misdirection). Enforce the 'familiar location' requirement strictly to prevent players from mapping entire dungeons from safety.
