Spells (3e)

The character immediately become aware of any attempt to observe the character by means of clairaudience/clairvoyance or scrying. The spell’s effect radiates from the character and moves as the character moves. The spell also reveals the use of crystal balls or other magic scrying devices. The character knows the location of every magical sensor within the spell’s area.

If the scrying attempt originates within the area, the character also knows its location. If the attempt originates outside this range, the character and the scrier immediately make opposed Scry skill checks. (A Scry check is the same as an Intelligence check for a creature without the Scry skill.) If the character at least matches the scrier’s result, the character gets a visual image of the scrier and a sense of the scrier’s direction and distance from the character (accurate to within one-tenth the distance).
