Mudwretch
CREATURE 2In its resting form, a mudwretch looks like a large puddle of thick, dark mud, heaped at the center in a slightly drier patch of loam. When a living creature approaches, though, the mudwretch lurches upward, piling its muddy flesh upon itself to form a roughly humanoid shape, often in vague mockery of the approaching creature's general form in cases where the creature is a humanoid itself.
Mudwretches possess a low level of intellect, and while they do not form societies or cultures of their own, they are attracted to ruins or abandoned settlements. They have little need to eat, but without a constant source of moisture, a mudwretch dries out, suffering from low throbbing aches until it can resaturate. Often, blood from living creatures has to do-a dried mudwretch is more dangerous to intruders than one that's comfortably wallowing on a river bank.
10 feet. The ground in the area is difficult terrain for all non-mudwretch creatures.
If a mudwretch takes any damage from Desiccate or a similar effect, takes 10 or more fire damage from a single effect, or spends more than 24 hours outside of a source of sufficient hydration (such as a swamp, river, well, or recent rainfall), it becomes dehydrated.
While dehydrated, the mudwretch can't Spew Mud, is Sickened 2, and is Slowed 1 until it either fully immerses in water, spends 1 minute in the rain, or rehydrates in another way (such as via Gory Hydration).
1d8+2 bludgeoning damage, DC 18 basic Fortitude
The monster deals the listed amount of damage to any number of creatures Grabbed or Restrained by it. Each of those creatures can attempt a basic Fortitude save with the listed DC.
Until it next acts, the mudwretch appears to be an ordinary puddle of mud. It has an automatic result of 20 on Deception checks to pass as a mud puddle and can make a fist Strike against a creature that walks onto the mud puddle as a reaction.
The mudwretch spews a 20-foot line of pressurized mud that deals 2d10 bludgeoning damage (DC 18 basic Reflex save). On a critical failure, a creature also takes a –10-foot status penalty to its Speeds for 1 round.
The mudwretch can't Spew Mud again for 1d4 rounds.
The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
