Swamp Sludge
The Swamp Sludge is a shapeless, sizeless monster which dwells in... swamps.
The Swamp Sludge is an enigma to all, sometimes only known as the feeling of something brushing past in murky water. It is said to be so slimy, that those who touch it feel icky for weeks.
Fighting Strategy
The Swamp Sludge cannot be killed. Any attempt to damage it sends acidic droplets flying in all directions, which eventually grow into smaller Swamp Sludges.
The Swamp Sludge cannot venture far from the water. Once it begins to dry out, it will immediately retreat to the nearest swamp.
