+35 (+30, +25) to hit (magical, reach 30, unarmed) 4d10+18 BludgeoningTremorsense (Imprecise) 60 feet
Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.
All-Around VisionThis monster can see in all directions simultaneously and therefore can't be flanked.
+1 Status to All Saves vs. MagicFast Healing 20A monster with this ability regains the given number of Hit Points each round at the beginning of its turn.
Maddening Cacophony (auditory, aura, incapacitation, mental)60 feet. A shoggoth constantly voices syllables and mutterings that mortals were not meant to hear. A creature entering the aura or starting its turn in the aura must succeed at a DC 38 will save or become Confused for 1 round (2d4 rounds on a critical failure). A creature that successfully saves is temporarily immune for 24 hours.
Constrict(2d10+15) bludgeoning, DC 40 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.
Eat AwayA creature that begins its turn inside the shoggoth takes 9d6 acid damage.
Engulf
DC 40 reflex, 6d6 acid damage, [/act escape dc=40], Rupture 40
The monster Strides up to double its Speed and can move through the spaces of any creatures in its path. Any creature of the monster's size or smaller whose space the monster moves through can attempt a Reflex save with the listed DC to avoid being engulfed. A creature unable to act automatically critically fails this save. If a creature succeeds at its save, it can choose to be either pushed aside (out of the monster's path) or pushed in front of the monster to the end of the monster's movement. The monster can attempt to Engulf the same creature only once in a single use of Engulf. The monster can contain as many creatures as can fit in its space.
A creature that fails its save is pulled into the monster's body. It is Grabbed, is Slowed 1, and has to hold its breath or start suffocating. The creature takes the listed amount of damage when first engulfed and at the end of each of its turns while it's engulfed. An engulfed creature can get free by Escaping against the listed escape DC. An engulfed creature can attack the monster engulfing it, but only with unarmed attacks or with weapons of light Bulk or less. The engulfing creature is Off-Guard against the attack. If the monster takes piercing or slashing damage equaling or exceeding the listed Rupture value from a single attack or spell, the engulfed creature cuts itself free.
Effect: Engulf and Swallow Whole
A creature that gets free by either method can immediately breathe and exits the swallowing monster's space.
If the monster dies, all creatures it has engulfed are automatically released as the monster's form loses cohesion.
GrabRequirements The monster's last action was a successful Strike that lists Grab in its damage entry, or the monster has a creature Grabbed or Restrained
Effect If used after a Strike, the monster attempts to [/act grapple] the creature using the body part it attacked with. This attempt neither applies nor counts toward the creature's multiple attack penalty.
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.
Although even raving fanatics and doom-saying prophets desperately claim the monstrous shoggoth is nothing more than a drug-induced vision or a thankfully unreal nightmare, the truth is altogether more dire. Shoggoths exist, yet they tend keep to the deepest of ocean trenches or the most remote of caverns and ruins, emerging to spread chaos and destruction in their slimy wakes.
The first shoggoths were created by an alien species to serve as mindless beasts of burden. Their vast bulk, incredible strength, and amorphous nature made them useful slave labor, and their ability to spontaneously form whatever new eyes, mouths, limbs, and other organs they might need made them incredibly versatile. Eventually, the shoggoths developed enough intelligence to rebel against their masters, and now they lurk, patient but potent, in the lightless deeps.
A shoggoth has goals and methods unknowable to humanoid beings. They remember their eons of servitude and, compared to their mysterious masters, humans, elves, dwarves and other intelligent beings are mere specks which crawl upon the surface of the world, indistinguishable from animals. When a shoggoth rolls its immense, hideous body over a band of explorers, engulfing them in a gelatinous press of flesh and gnawing teeth, it is not so much evil as uncaring.
Shoggoths can become the object of worship for humanoid cults dedicated to chaos and entropy. The shoggoth does not respond to this worship, but it can be counted on to consume any hapless victim the cult can capture and sacrifice to it. Rumors of shoggoths that have developed even greater intellects are, one would hope, just that, for the damage a shoggoth capable of reasoning could wreak upon a world is unsettling to say the least.
Traits
This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
AberrationAberrations are creatures from beyond the planes or corruptions of the natural order.
AmphibiousAn amphibious creature can breathe in water and in air, even outside of its preferred environment, usually indefinitely but at least for hours. These creatures often have a swim Speed. Their bludgeoning and slashing unarmed Strikes don't take the usual –2 penalty for being underwater.
