Euchambersia - Venomous Cave Stalker

[ArkUser123]

Another recently made creature of mine (really hope there isn't a problem with submitting multiple creatures), Euchambersia is a synapsid that I grew fond of the moment I saw it in Walking with Monsters a few years ago. I have 2 more Aberration themed creatures to submit, those being Eryops and Purussaurus, however I think I'll leave it at 3 for now. Enjoy!

 

Euchambersia

Diet: Charge light, meat/carrion
Rider Weaponry: Yes
Temperament: Voracious

Wild
This unusual synapsid seems to have adapted quite well to living on the broken Ark. Even on Earth in ancient times they were the only known synapsids that were naturally venomous. That remains the same on the Ark, however there’s something even more unusual about them. They appear to act as seekers do and feed on the energy from charge light. They will viciously hunt down Bulbdogs, Glowtails, Featherlights, Shinehorns, and any other creatures that produce charge light. That energy causes them to become extremely hyperactive but surprisingly makes them become passive and almost friendly in a way. However, don’t let this fool you because while they can become friendly for a little while, if they consume too much charge energy they become so aggressive and terrifying that they seem like a whole different creature! In fact, when Euchambersia consumes too much charge light, it's capable of walking on the Surface in broad daylight. It’s for this reason that many survivors have attempted to tame this seemingly normal medium sized synapsid. But few have been successful and lived to tell the tale.

Domesticated
The best way that I’ve seen a survivor domesticate the feral Euchambersia is by using various charge light based items on it. They tend to start by throwing plant species Z fruits at the creature to draw its attention and start satisfying its need for charge light. However I’ve noticed that Euchambersia tend to have a few Seekers nearby due to them both having the same kinds of prey. They don’t have any kind of symbiosis as far as I can tell however the Seekers will definitely pose a threat or at least an inconvenience to any survivors looking to tame a Euchambersia. Anyways, when the Euchambersia starts to get closer to the survivor, they pull out a charge lantern. The creature is mesmerized by the blinding light of the lantern and begins to walk slowly towards the survivor. But because the survivor was brave enough to not run away and smart enough to not give the Euchambersia too much charge light, they earned themselves a relatively powerful and very quick and agile mount to traverse the endless caverns of the broken ark. Albeit with a bit of venom and latent insanity...

Controls
Left click: Bite: 60 base damage, inflicts “Noxious Venom” which rapidly drains the victims health stam over 1 min, health and stam drained is based on damage dealt by the Euchambersia (10% of damage dealt, meaning 60 damage bite will deal 6 damage per sec for that 1 min), each bite resets the 1 min timer but doesn’t increase the health and stam drain

Right click: Claw swipe: 50 base damage, ignores armor and breaks armor quicker

C - Pin: 70 base damage, holds smaller creatures to the ground (drag weight of 250 and lower), pinned creatures can still attack but their damage is reduced by 20%, Euchambersia will automatically attack extremely quickly with its bite attack (similar to Thyla pounce) until the victim is dead, players can struggle to escape like with bloodstalkers but only if they’re unmounted

X - Roar: increases movement speed by 15% for 30 sec for Euchambersia and it’s rider only

Control: Hellion Rage: Euchambersia has a meter that fills up by killing charge light creatures, consuming energy from batteries, and toggling an option on the radial wheel to allow it to absorb charge from charge lanterns. Once the meter fills up, pressing control activates Hellion Rage which when activated makes Euchambersia unleash a fearsome roar that scares away creatures that have a drag weight of 300 or less. Hellion Rage increases Euchambersia’s damage by 30%, attack speed by 50%, and movement speed by 50% until the meter goes all the way back down. In order for the charge meter to fill, Euchambersia has to absorb 5000 charge from any of the listed sources (it can also be told to absorb charge from charge nodes but the build up is very slow, around 1 charge per minute instead of over 100 charge for killing a charged creature since it’s based on the creature’s charge capacity stat). While in Hellion Rage, Euchambersia and its rider are able to walk on the Surface during the day without being damaged by the flames. The rider is also able to dismount safely but will begin to take damage if they don’t stay close to their Euchambersia. While on the Surface during the day (in Hellion Rage), Euchambersia will receive an additional 20% increase to its damage and movement speed as well as a 10% health regen increase. After Hellion Rage ends, Euchambersia becomes exhausted and can no longer activate hellion rage for the next 5 min.

Extra Info
Euchambersia isn’t immune to radiation unless it’s in Hellion Rage. However the rider isn’t protected.

Euchambersia can climb exactly like a Deinonychus by jumping at a climbable wall. It’s not immune to fall damage, but takes reduced fall damage.

Euchambersia’s saddle can be learned at level 70.

Euchambersia is about the size of Ark’s Thorny Dragon.

Euchambersia can be told to sit for increased healing.

Euchambersia spawns around charge sources (light pets, glowbugs, charge nodes etc), Seekers, and occasionally on the Surface on Aberration.

Wild
Solitary and skittish during the day, the Euchambersia volunoctus undergoes a rapid transformation during the hours of the night. Like it's relative the Purlovia, these "Therocephalians" are carnivorous, though unlike the latter they do not hide underground and prefer to hunt their prey more actively. With a low-slung body and a cryptic patterning, it should come as no surprise that Therocephalians are ambush predators. They are incredibly patient hunters, slowly creeping right up to their prey before striking. 
As if stealth and camouflage weren't enough, the Therocephalian is armed with a potent secret weapon. From glands beneath their cheeks they can produce a strong form of neurotoxin. Though not deadly outright, this venom directly attacks the nerves, causing excruciating muscle cramps and temporary paralysis. 
Therocephalians will latch onto a victim with a vice-like grip and quite literally "chew" the venom into the flesh of their prey, before backing off to let the poison do its work. Once its prey has been subdied, the Therocephalian moves in to feed, oftentimes while the victim is still alive and conscious. 

Tamed
Despite their small size and rather fragile build, Therocephalians are highly sought-after by many tribes all across the island. Their low-slung profile means they are very hard to detect, making them excellent scouting mounts. A tamed Therocephalian's venomous bite can also be used to weaken opponents in combat, and has the added benefit of making afflicting animals more susceptible to torpor-inducing attacks! 


In-Game Appearance and Function
For appearances, I imagine the Therocephalian would be somewhere between a Purlovia and a Dire Wolf in size. They'd be somewhere inbetween in terms of speed and physical power, possessing the normal bite and scratch attacks alongside a powered-up bite which would apply their venom. 
In short, the Therocephalian would function like a scout/support mount. Their low profile makes them harder to spot, effectively immune to the marking abilities of other animals like the Snow Owl or the Dire Wolf. They can enter a "stalking" mode, which would slow their movement speed while drastically reducing the range that AI could spot them from. Entering this mode while a certain distance from an enemy would cause them to lose aggro. This would also allow them to move much closer to active turrets and aggressive tames before being spotted. Using this ability, the Therocephalian might make for a good scouting mount when approaching an enemy base or stealing eggs from an angry creature, like a Rock Drake. 
The venomous bite is where the Therocephalian really shines. Their venom would cause a specific debuff depending on what you are attacking. When attacking tamed animals, the Thero's bite causes weakness and a slower stamina regeneration.
When attacking wild animals, the Thero applies a debuff that makes torpor-inducing attacks far more effective. If you take a Therocephalian to help you with a tame, you could turn a 100-dart slog into a quick, efficient experience.

With abberation being something of a horror setting with the Nameless crawling out if the ground like zombies, reapers being very reminiscent of the alien movie, along with the other creatures, it only seems fitting that the animal should also bring a horror movie monster vibe to this horrifying ark.

Enter Euchamberaia, the oldest known tetrapod to be venomous. 

 

Ark varient of this creature would have to, like with many suggestions in the past, take creative liberties in order to accentuate the horror factor of the creature. 

 

For one it's venom should be unique, causing spasm in dinos and even causing them to rage in confusion,making them attack their team-mates while in humans it could cause hallucinations for a period of time. This venom should of course need to be applied with many bites, perhaps even a special bite ability that applies this effect with enough hits on a creature.

It should have a haunting howl, sounding otherworldly and terrifying. This could be purely cosmetic though I believe forcing animals afflicted by venom to retreat would be a very nice touch, leaving the rider out of control as his mount flees in terror.

In terms of looks it should have a tapidum lucidum or in other words night vision and glowing eyes. Giving it that extra sense of horror as you can see it's two glowing eyes watch you in the darkness. This could open up a weakness to flashes of light from plant species z or the charge lantern.

They should be found in the radiation and blue zone, leaving this nightmare out of the safer green zone.

Size wise it should be around the size of a thylacoleo, giving it enough size to be terrifying on the ground for humans while still being big enough to strike at larger targets. 

Taming this creature should be unique, my suggestion would be to use plant species z or a charge lantern to force them to cover their eyes before feeding then their favorite food, Nameless venom. Giving you only a short window of time to flash them and feed them before moving away. 

For the time being, the picture to show how it would potentially would look is going to be a still from the walking with monsters documentary series which introduced me to this animal. Though I'd love to have an interpretation of this creature in a horror setting that isn't primeval.
