Some places create supernatural echoes that seem to come from random directions, or even all directions at once. An area suffused with misleading echoes imposes a –4 penalty on hearing-based Perception checks, and a listener must succeed at a DC 15 Wisdom check whenever she detects a noise, or else she believes the noise came from a random direction instead of its actual direction. Further, the misleading echoes can replicate the effects of ghost sound (DC 11) once per minute. Any creature that fails a Wisdom check or Will save to resist the effects of the misleading echoes takes a –2 penalty on saving throws to resist fear effects for as long as it remains in the area of the misleading echoes, and for 1 minute thereafter.
