Juvenile Cave Worm (Azure)

Tremorsense (Imprecise) 100 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.

Relentless — When a juvenile cave worm gains the Paralyzed, Slowed, or Stunned condition, reduce the duration by half, to a minimum of 1 round. It also recovers from penalties to its Speeds and the Immobilized condition at the end of its turn. Finally, it ignores non-magical difficult terrain and treats greater difficult terrain like difficult terrain.

Shake It Off — Frequency once per day

Trigger The juvenile cave worm would be affected by a condition or adverse effect (such as Cursed Metamorphosis)

Effect The juvenile cave worm negates the triggering condition or effect. Effects from artifacts, deities, or a similarly powerful source can't be avoided in this way.

Clumsy Leap — The cave worm flings its body, Leaping 30 feet. If it lands next to a creature, it can Strike that creature with its jaws. If the jaws Strike fails, it can Strike with its body using the same multiple attack penalty as the failed jaws Strike, but it becomes Off-Guard until the start of its next turn.

Killing Shake —

Rock Tunneler — A juvenile cave worm can burrow through solid stone at a Speed of 10 feet. It can leave a tunnel if it desires, and it usually does.

Swallow Whole (attack) — Medium, 1d8+10 bludgeoning, Rupture 18

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.
