You can observe a creature at any distance. If the subject succeeds on a Will save, the spell fails. The difficulty of the save depends on how well your knowledge of the subject and what sort of physical connection (if any) you have to that creature. Furthermore, if the subject is on another plane, it gets a +5 bonus on its Will save.
If the save fails, you can see and hear the subject and its surroundings (approximately 10 feet in all directions of the subject). If the subject moves, the sensor follows at a speed of up to 150 feet.
As with all divination (scrying) spells, the sensor has your full visual acuity, including any magical effects. In addition, all of the following spells function reliably through the sensor: detect chaos, detect evil, detect good, detect law, Detect Magic, Message, Read Magic, and Tongues.
If the save succeeds, you can’t attempt to Scry on that subject again for at least 24 hours.
This spell is a more powerful version of Scrying.
