WW: Homonculous

You can see a destinct creature or survey a specific area. The target must make a Intelligence saving throw, which is modified by how well you know the target and the sort of physical connection you have to it. If a target knows you're casting this spell, it can fail the saving throw voluntarily if it wants to be observed.

On a successful save, the target isn't affected, and you can't use this spell against it again for 24 hours.

Instead of targeting a creature, you can choose a location you have seen before as the target of this spell. When you do, the sensor appears at that location and doesn't move.
