A neothelid is a 50-foot-long, wormlike
creature with a mass of tentacles at one end. In the midst of this nest of tentacles is a toothy maw. The
creature has no eyes or other sensory organs as such, though it unerringly senses the location of prey.
Blindsight (Ex): A neothelid is blind but can ascertain all
creatures and objects within 500 feet by nonvisual means. Beyond that range, all targets have total concealment with respect to the neothelid.
Breath Weapon (Su): Once every 1d4 rounds, a neothelid can breathe a 50-foot cone of
acid that deals 14d10 points of
acid damage to every
creature in its area. A successful Reflex save (DC 10 + 1/2 the neothelid's Hit Dice + its Constitution modifier) halves the
damage.
Damage Reduction 15/+2 (Su): A neothelid ignores the first 15 points of
damage dealt by any weapon with a magical bonus lower than +2. In campaigns without magic
weapons, the GM can either disregard the neothelid's
damage reduction or apply it only to certain types of
weapons (ballistic, bludgeoning, piercing, slashing, or sonic/concussion).
Psionics
(Sp): At will-
charm person,
clairaudience/ clairvoyance,
detect thoughts,
levitate,
suggestion,
telekinesis. Manifester level 10th; save DC 10 + neothelid's key
ability modifier + power level.
Improved Grab (Ex): To use this
ability, the neothelid must hit a single opponent at least one
size category smaller than itself with two tentacle rake attacks in the same round. If it gets a hold, it automatically deals
damage for two tentacle rakes each round that the hold is maintained, and it can swallow in the next round.
Swallow Whole (Ex): If a neothelid begins its turn with an opponent two or more
size categories smaller than itself held in its mouth, it can attempt a new
grapple check as though trying to pin the opponent. If it succeeds, it swallows its opponent, automatically dealing bite
damage. Once inside the neothelid, the opponent takes bludgeoning
damage equal to the neothelid's tentacle rake attack plus 1d6 points of
acid damage per round from the monster's gizzard.
A successful
grapple check allows the swallowed
creature to climb out of the gizzard and return to the neothelid's maw, where another successful
grapple check is needed to get free. Alternatively, the swallowed
creature can attack from inside the gizzard using claws or a Small or Tiny slashing
weapon. Dealing at least 25 points of
damage to the gizzard (
Defense 20) in this way creates an opening large enough to permit escape. Once a single swallowed
creature exits, muscular action closes the hole; thus, another swallowed
creature must cut its own way out. A Gargantuan neothelid's gizzard can hold 2 Large, 8 Medium-
size, 32 Small, or 128 Tiny or smaller opponents.
