This creature resembles superficially a mindflayer with glistening skin of a green so dark as to be only a couple shades of black with long, vein-like patches of a much lighter green seen just beneath that twitch and squirm. The most disturbing aspect of it however is the patches of small tentacles that seem to sprout at random all about its body in irregular patches, even from where eyes should be. The thickest however grow as normal from the mouth as a standard mindflayer, though also down the spine in a writhing line.
A plethelid is a creature even rarer than a neothelid, but from similiar origins. When a stray humanoid happens upon a pool of dying and starving mindflayer tadpoles it is generally the last thing he or she sees. A feeding frenzy insues with dozens of the larvae fighting for a taste of his brain matter and neural energy. The strongest lodge themselves in seperate portions of the head and spinal column and fight the others for the space. Eventually their bodies meet and merge into one mind as a plethelid. Because of the number of growing and constantly feasting tadpoles the body itself tends to become hulking and massive, resembling little their gaunt brethren. Its hunger and energy needs is as that of a dozen normal mindflayers, and thus it grows as a predator with little chance to do ought else but seek out victims to feed upon.
If a party of creatures happens upon the pool and are converted the resulting plethelids generally form into horrendous packs whoes cunning and tactics know no bounds.
Plethelids stands almost 12 feet tall and is broad to match. They can weigh nearly half a ton. Plethelids speak Undercommon, though tend to communicate silently through their telepathy.
Plethelids are horrendously effective combatants, using mind and body to capture one victim after another to sate their hunger. They prefer to remain as silent as possible, stalking large groups, and picking off the stragglers for as long as possible without alerting the others. Once discovered though they are rarely concerned, blasting them into submission and attempt to feast upon as many brains as possible before the group stirs.
While in packs they often join their minds together and organize attacks as many parts of a single entity, coordinating flawlessly with complex strategies.
Plethelids can “see” by emitting high-frequency sounds, inaudible to most other creatures, that allow them to locate objects and creatures within 120 feet. A silence spell negates this and blinds the plethelid.
Distributed Mind (Ex):
Because of the plethelids origins it has no main brain, though has complex cerebral nodes located throughout its body. As such it is not instantly killed by the loss of its head such as a critical blow from a Vorpal weapon. It does however lose four tentacle attacks, its mindblast becomes a standard 60 ft. cone, and it takes a permanent -4 penalty to all mental stats unless its head can somehow be grown back, such as from the Restore Extremity power.
A plethelid that begins its turn with at least four tentacles attached and that makes a successful grapple check automatically extracts the opponent's brain, instantly killing the creature. This power is useless against constructs, elementals, oozes, plants, and undead. It is not instantly fatal to foes with multiple heads. A plethelid has two orifices from which it can extract, one in the normal location and another much larger one hidden within the tentacles upon its back.
Improved Grab (Ex):
To use this ability, a plethelid must hit a Small to Large creature with its tentacle attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity. If it wins the grapple check, it establishes a hold and attaches the tentacle to the opponent's head. A plethelid can grab a Huge or larger creature only if it can somehow reach its head.
If a plethelid begins its turn with at least one tentacle attached, it can try to attach its remaining tentacles with a single grapple check. The opponent can escape with a single successful grapple check or an Escape Artist check, but the plethelid gets a +1 circumstance bonus on the check for every tentacle that was attached at the beginning of the opponent's turn.
A plethelid gains a +4 racial bonus on grapple checks. This bonus is included in the statistics above.
Mind Blast (Sp):
A plethelid can discharge a devasting psionic attack in the form of a 20 foot burst in all directions or a single 60 foot cone. Anyone caught in the blast or cone must succeed on a DC 19 Will save or be stunned for 3d4 rounds. The save DC is Charisma-based.
