Spells (35e)

You can see and hear some creature, which may be at any distance. If the subject succeeds on a Will save, the scrying attempt simply fails. The difficulty of the save depends on how well you know 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 the subject's immediate 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, the following spells have a 5% chance per caster level of operating through the sensor: detect chaos, detect evil, detect good, detect law, detect magic, and message.

If the save succeeds, you can't attempt to scry on that subject again for at least 24 hours.
