Ice mirror creates an invisible magical sensor at a specific location that allows you to see as if you were at that location. You don’t need line of sight or line of effect, but the locale must be known—a place familiar to you, or an obvious one. Once you have selected the locale, the sensor can move at a fly speed of 10 feet, though it must have an unobstructed path to do so (the sensor is approximately 1 foot in diameter, and cannot squeeze through smaller spaces). As with all divination (scrying) spells, the sensor has your full visual acuity, including any magical effects. Ice mirror functions only on the plane of existence you are currently occupying.
