Gluttonworm

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.

15 feet. Ground in the aura is greater difficult terrain.

The gluttonworm recovers from the Paralyzed, Slowed, and Stunned conditions at the end of its turn. It's also immune to penalties to its Speeds and the Immobilized condition, and it ignores difficult terrain and greater difficult terrain.

A gluttonworm in contact with a significant body of sand, such as a desert or beach, gains fast healing 10. If the gluttonworm is subject to persistent bleed, the flowing blood quickly congeals with the sand covering its body, instantly ending the bleed duration and giving the gluttonworm a +2 circumstance bonus to AC until the end of its next turn.

Trigger The gluttonworm Grabs a creature, or a creature fails a Reflex save against a Gulping Charge Effect The gluttonworm uses Swallow Whole.

The gluttonworm Strides up to double its Speed and can move through the spaces of Large or smaller creatures, gulping each creature whose space the worm enters and attempting a body Strike against each of them. The gluttonworm can use this Strike on each creature only once in a single use of Gulping Charge. Creatures can attempt a DC 41 reflex save against this damage.

The gluttonworm exhales swirling sand in a 60-foot cone. Creatures in the area must attempt a DC 41 reflex save. It can't Spew Sandstorm again for 1d4 rounds. Critical Success The creature is unaffected. Success The creature takes 4d6 slashing damage and 4d6 bludgeoning damage from the scouring sand. Failure The creature takes 8d6 slashing damage and 8d6 bludgeoning damage from the sand, and is Dazzled until the end of its next turn. Critical Failure The creature takes 12d6 slashing damage and 12d6 bludgeoning damage and is Blinded for 1 hour.

Huge, 3d10+17 bludgeoning and 2d6 slashing, Rupture 36 The monster attempts to swallow a creature of the listed size or smaller that it has grabbed or restrained in its jaws or mouth. If a swallowed creature is of the maximum size listed, the monster can't use Swallow Whole again. If the creature is smaller than the maximum, the monster can usually swallow more creatures; the GM determines the maximum. The monster attempts an athletics check opposed by the grabbed creature's Reflex DC. If it succeeds, it swallows the creature. The monster's mouth or jaws no longer grab a creature it has swallowed, so the monster is free to use them to Strike or Grab once again. The monster can't attack creatures it has swallowed. A swallowed creature is Grabbed, is Slowed 1, and has to hold its breath or start suffocating. The swallowed creature takes the listed amount of damage when first swallowed and at the end of each of its turns while it's swallowed. If the victim Escapes this ability's grabbed condition, it exits through the monster's mouth. This frees any other creature grabbed in the monster's mouth or jaws. A swallowed creature can attack the monster that has swallowed it, but only with unarmed attacks or with weapons of light Bulk or less. The swallowing 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 swallowed creature cuts itself free. A creature that gets free by either Escaping or cutting itself free can immediately breathe and exits the swallowing monster's space. Effect: Engulf and Swallow Whole If the monster dies, a swallowed creature can be freed by creatures adjacent to the corpse if they spend a combined total of 3 actions cutting the monster open with a weapon or unarmed attack that deals piercing or slashing damage.

Trigger The monster's last action was a successful Strike that lists Improved Grab in its damage entry, or the monster has a creature Grabbed or Restrained Effect If used after a Strike, the monster attempts to Grapple the creature using the body part it attacked with as a free action. This attempt neither applies nor counts toward the creature's multiple attack penalty. The monster can instead use Improved Grab as an action and choose one creature it's grabbing or restraining with an appendage that has Improved Grab to automatically extend that condition to the end of the monster's next turn.
