Deepest Fear

A bogeyman is cloaked in a 30-foot aura of fear. This aura manifests as a shifting haze of images that reflect the viewer's deepest fears. The first time it ends its turn within the aura, a creature must succeed at a DC 25 Will save or become shaken for as long as it remains within the aura. If a creature succeeds at saving throw, it cannot be affected again by the aura for another 24 hours. This is a fear effect. The DC is Charisma-based.
