Knight, are you the last one posting here?
anyway, here is my writeup, FINALLY (grumble grumble stupid @#$*&! server...) what do ya think? more later today (hopefully...)
This powerful outsider is a fearsome loner that wanders the planes, heedless of the destruction it may case. This primal force of nature moves leisurely throughout the worlds, watching the universe flow past it. It has an irrational hatred of all ambulatory animal life, feeling that all life that moves on its own must die. This elemental monster hails from a plane of wood, where it is surrounded by unwholesome flora. Everywhere it goes, flowers bloom, vines thrive, and toadstools sprout – poisonous flowers, throttling vines, and deadly toadstools that is – on even the smallest barren patches of earth. On its home plane, this creature fills an ecological void similar to that of the genies on their various elemental planes.
This creature is composed of a tightly wound network of fibers that resemble withered mandrake root, that hitches a ride on plant-creatures and normal plants. Its true body resembles a vaguely humanoid shape composed of rotting, brown plant material covered in a thick bark that constantly grows and reshapes itself over old wounds. Most living creatures are repelled by the sight and smell of this creature instantly. Its true body is not very strong - but extremely tough and can take a lot of punishment, to those can get close enough to find out. It is methodical and relentless, though perhaps a little slow, but powerful enough to take its time with its foes. It prefers to move at a leisurely walking pace, giving it time for unwholesome plant life to rapidly grow, flourish and die with its passing.
Everywhere the creature ventures it remains surrounded by twisted, dark and deadly plants that spout, grow, wither and die - some in a moment’s passing. To enter the sphere of influence of this creature and pass among these abominations is extremely unsettling and potentially dangerous due to the often poisonous and aggressive nature of these frightful creations. This rapid growth of plants is a magical defense with much of the resulting life being ambulatory, poisonous, and aggressive or simply providing a thorny barrier if need be. The great majority of the time the plants pop up randomly, brought into being through the subconscious desire of the creature. This magical circle of ever changing and mutating plant life is the creature’s primary defense. Its strong mind allows it to see all the possibilities around it, and when confronted it can choose which plant will sprout and defend it.
This creature comes into being in a larval stage, which resembles a tiny little brown acorn with stubby limbs, which develops in a host-body. Its springs forth when mature, though most meet their end quickly without reaching the powerful adult stage. As the larvae grows, it assumes a skin of bark, and grows larger and larger until it achieves an almost humanoid form. This full-sized body is covered in pustules that contain spores for reproduction, which are attached to thorns that shoot out at its death, to continue the life cycle. Adults are able to become incorporeal, and leave their bodies behind to possess other plant creatures or hide in normal plants. Thus, it can hide its real body from foes, while extending its power wherever the body remains. From this body extend a series of incorporeal, invisible "rootlets" that extend outward from it over great distances.
In its true body, this creature is not a very powerful melee combatant, and prefers to use its powers against foes. Instead of fighting one-on-one, it focuses on keeping opponents at a distance, incapacitating them, or causing hindrances so it can take its time and distance to deal with intruders. It will only engage in combat with foes if they are weak or if it possessing a host plant. If such a fight goes badly for it, it will disengage from that host and either possess a new host, or return to its real body to plan revenge.
Around this creature’s true body as well as any other form it may inhabit, it constantly projects a powerful magical aura with a radius of 5 feet per Hit Die it has. Within this aura, three different effects may take place: plant growth, noxious growths, and decomposition. The aura may switch between plant growth and decomposition at will, but may only cause one of these effects in any given round. The noxious growths are created at all times, regardless, unless the creature consciously wills it to cease. The aura also affects any host body the creature is using, causing other plants to sprout from it and attack.
