As a free action, a flail snail can excrete a trail of mucus that covers its space and lasts for 10 minutes. This mucus comes in two types: slimy and sticky. A character who attempts to move through an area covered in slippery mucus must make a DC 14 Reflex save each round or fall prone. Sticky mucus transforms squares into difficult terrain. Only one type of mucus can be in effect at a time in any one square. Flail snails can move through either type of slime with ease. A square of mucus exposed to a fire source dries and reverts to normal. The save DC is Constitution-based.
