Filth Wave Frequency once per minute; Effect The sewer ooze unleashes a wave of filth, covering all creatures within a 20-foot emanation. Each creature in the area must succeed at a DC 17 Reflex save or take 1d4 acid damage and take a -10-foot penalty to its Speeds for 1 minute (on a critical failure, the creature also falls prone). A creature can spend an Interact action to clean someone off, decreasing the Speed penalty by 5 feet with each action.
These amorphous masses of sewage and other detritus make their way through filthy culverts beneath cities large and small.
