Morgathrells are massive sea creatures that
anchor themselves to the ocean floor and prey on
whales and ships.
A morgathrell resembles an enormous gray
and black worm 20 feet in diameter, 60 feet
long, and weighing over 30 tons. Two tentacles,
hundreds of feet long and covered in bony spines
emerge from a morgathrell’s sides. A morgathrell’s
three-pronged mouth can stretch open to almost
twice the width of its body, revealing numbers of
enormous, jagged white teeth.
A morgathrell spends most of its life asleep,
half its body buried in the ocean floor, developing a
covering of silt and plants. This natural camouflage
allows a morgathrell to avoid frightening potential
meals. When a moving target of sufficient size
does approach a morgathrell, the creature rises up,
whipping its tentacles through the water and trying
to drag its prey to its mouth. Vast fortunes have
been found within the bellies of morgathrells: the
former cargos of devoured ships.
Combat
Morgathrells focus on one opponent at a
time, doing everything they can to devour their
enemies and never realizing the possibility of
defeat.
Capsize (Ex): A submerged morgathrell
that surfaces under a boat or ship less than 20 feet
long capsizes the vessel 95% of the time. It has a
50% chance to capsize a vessel from 20 to 60 feet
long and a 20% chance to capsize one over 60 feet
long.
Improved Grab (Ex): To use this ability, a
morgathrell must hit with a tentacle rake attack. It

can then attempt to start a grapple as a free action
without provoking an attack of opportunity. If it
wins the grapple check, it establishes a hold and
can transfer a grabbed opponent to its mouth on its
next turn, swallowing the creature.
Swallow Whole (Ex): A morgathrell
can transfer a grabbed Huge or smaller victim
from a tentacle to its mouth as a move action,
automatically swallowing the creature. Once
inside, the opponent takes 4d8+12 points
of bludgeoning damage per round from the
morgathrell’s gizzard. A swallowed creature can
cut its way out by using a light slashing or piercing
weapon to deal 40 points of damage to the gizzard
(AC 18). Once the creature exits, muscular action
closes the hole; another swallowed opponent must
cut its own way out.
A Gargantuan morgathrell’s interior can hold
2 Huge, 8 Large, 32 Medium, 128 Small, or 512
Tiny or smaller opponents.
Blindsight (Ex): Morgathrells can sense
all foes within 300 feet by water vibrations.
Beyond that range, they are considered blinded.
Morgathrells are invulnerable to gaze attacks,
visual effects of spells such as illusions, and other
attack forms that rely on sight.
Skills: A morgathrell has a +8 racial bonus
on any Swim check to perform some special action
or avoid a hazard. It can always choose to take 10
on a Swim check, even if distracted or endangered.
It can use the run action while swimming, provided
it swims in a straight line.
*A morgathrell’s accumulation of earth and
sea life over its body grants it a +16 circumstance
bonus on Hide checks underwater.
