The building of automata is a science, even in the infernal realms. Some regions are host to what is colloquially referred to as "Darkstone", a deep purple coloured stony matter - which planar prospectors would tell you tends to house veins of literal corruption. When one wants to make a construct it is best to use the materials availed to you, and this is no exception. Still, making it shaped like a panther is a bit on the nose... surely? There can't be that many advantages if it is primarily meant to guard places, right? Instinct: To serve

• Feign inanimation as an art piece of purple stone
• Phase through the same purple stone that it is built from

Instinct: To fulfill a contract

• Shoot arrows

Instinct: To fulfill a contract

• Bully for coins

There's a saying about old broadcast towers--be careful of any signal on a dead channel, because you don't know who's listening. Sometimes those things take the form of what's being broadcast... but other times, you get something more dangerous. Creatures of static and noise of nebulous form between lines of reality. They may not understand the world around them, but they can communicate, and they know they need a broadcast to live. Instinct: to share

• viral pain
• nasty earworm

Everyone wants money. Coins. Treasure. They lust after. But it has a cost. That cost is me. Instinct: To turn your greed against you

• Use treasure as a weapon
• Hurl: target gets flung across the room.
• Turn your greed against you

The fauna found in the more infernal realms show many aspects - not merely bloodthirstiness and violence. Although indeed these specimens are not non-violent by any means, but they have more insidious ways to attack and feed. They resemble giant moths, the size of terrestrial dogs, they are drawn to the minds of sleepers which are akin to the brightest of flames to them, and feed upon their dreams or nightmares to grow in power and supposedly begin the next stage of their life cycle... wherever that goes. However if confronted they can force those that fight them into a slumber to better take advantage. If forced to they will simply bite their prey until death, but they would much prefer to drain their essence until they are empty husks bereft of dreams first... Instinct: To feed on flesh or dreams

• Spray forth exhausting dust
• Vanish via active camouflage
• Feed on the dreams and nightmares of the sleeping and grow stronger

What would happen if a insane wizard and a powerful necromancer had a experiment together? The skeleton chimera is a close answer. With the best of both magical powers by not needing any kind of resources besides the necromantic energy the Skeletal Chimera is born. Not only is capable of the dreadful ways of perverting nature like the Chimera, the Skeletal Chimera perverts the way of the life itself. If the chimera was the worst sort of abomination affronting all natural life the skeletal chimera is an intentional way to affront all natural laws. Instinct: To do as commanded even after death

• To ensure obedience
• Arise dreadful allies

When the Arcane of the world doesn't know what to do, it makes frogs. Lots of frogs. These things get everywhere and alter reality in small, odd ways. Thankfully, they're just frogs--but it can be really hard to actually get rid of them. Instinct: to scatter

• spread wild magic
• bend reality to any extent
• croaking and crooning for pals

Dothi Inquisitors judge magic, but few have seen by what measure they do so. Few on words and low on patience, an Inquisitor will strike the ground hard much like their god did a few millennia prior. While not necessarily evil, few can say they appreciate the presence of someone so prone to violence and force. Instinct: to purge

• judge with a blade
• magic-canceling incantations

When encountered in somewhere far more literal, such as the more infernal realms, corruption tends to manifest as a viscous - almost lava-like fluid, usually seen as a dark purplish hue of some kind. At times it manifests in a more concentrated form, usually in veins akin to veins of ore in the mortal world - and in this case tends to be more solid - if not crystalline - in nature. Few mortal alchemists would consider the idea but amongst the desperate and depraved that lurk in those places, some seek to refine concentrated corruption to an even greater degree. If that was possible one could (if so foolish) build an automaton out of such a substance, lashed together by fell magic and ill intent, such an automaton could be feared even in such a dark place. Luckily that is not only incredibly unlikely but also far beyond our own world... right? Instinct: To corrupt

• Corrupt or destroy with beams of corrupt energy
• Vomit forth abyssal magic beyond mortal comprehension
• Manipulate corruption and the corrupted
