The warded creature or object becomes difficult to detect by
divination spells such as clairaudience/clairvoyance, locate
object, and detection spells. Nondetection also prevents location
by such magic items as crystal balls. If a divination is
attempted against the warded creature or item, the caster of the
divination must succeed at a caster level check (1d20 + caster
level) against a DC of 11 + the caster level of the spellcaster
who cast nondetection. If the character cast nondetection on the
character's self or on an item currently in the character's
possession, the DC is 15 + the character's caster level.
If cast on a creature, nondetection wards the creatures
gear as well as the creature itself.
