Bag of Utter Rot

This heavily worn, magical satchel smells of mold and earth.

The bag can be opened (Bonus Action) at which time an illustory torrent of Rot Grubs spill out, covering a 5ft square adjacent to the holder of the bag.

Any creature within sight of the bag (up to 60ft) must roll a DC 15 CHA check.

Upon failure, it is Frightened of the bag until succeeding on rolling a check. 
Upon success it sees through the illusion and cannot be frightened of the bag for 24hours.

This bag can only be used once in a 24hour period.

Notes: Frightened
