Often confused with will-o’- wisps, these shimmering lights also tend to lead unwary passersby to their dooms. Witch lights appear as flickering lights resembling lantern or torch flames, but can be seen only with a successful DC 10 Perception check. A result of 30 or higher on the Perception check allows the viewer to identify the witch light as a mirage. The witch light seems to move with the viewer, retreating if the creature moves toward it and following if it moves away. Some witch lights have a mind of their own, or are controlled by malevolent entities, and lead viewers toward specific places—often pits or other hazards, but sometimes treasures or long-buried secrets. Creatures actively following a witch light take a –4 penalty on Perception checks and a –4 penalty on Reflex saves to resist the effects of traps and hazards.
