Pan fanatic

In the north western part of Everwoods there lays a peculiar sight. A dense maze of bamboo where every shoot is at least 10 feet in diameter. The tree tops cover most of the sun light, allowing only a few rays to enter. What makes the matters worse is the snaking fog that enters it every morning. This place is the source of many rumors and dark stories. Many of those tales talk of strange and twisted creatures whose screams are told to make even the bravest warriors soil their briefs. But is there any truth to those tales of horror?
 

Song most foul

You can play your Pan pipes to produce a horrid tune. Each creature that is in a 30 ft radius around you must make a DC 13 Charisma saving throw. On a fail they become frightened of you for 1 minute. The effected creatures can make a new save at the end of each of their turns, ending the effect on a success. You regain the use of this feature at the next dawn.
