Creeping Ectoplasm CR 2
A minor haunt devoid of any shred of individuality or history, manifesting as a shapeless blob of ectoplasm.
When this haunt is triggered, a mass of ectoplasm appears out of nowhere, covering the area with a blanket of luminescent green goo that acts like a grease spell (DC 11).
The area where it manifests must be consecrated or hallowed, even temporarily.
