Blizzard Nimbus	2	Snow, Rain	Having frozen over, this nimbus angrily rains down shards of ice in an attempt to expel all of it. What it doesn't know is that it could just leave the cold environment.

Crystal Drifter	2	Snow, Rain	The howling winds of a blizzard give flight to this otherwise cumbersome entity composed of ice.

Cyberflies	1	Synthwave	Small digital wisps that flutter about cyberspace.
Cystal	1	The Corruption	A ghastly creature that patrols the murky depths of the Corruption. Their crystalline bodies emit a disorienting, sense-obscuring frequency, so steer clear!

Feral Shambler	1	Briar	The line between flora and fauna is blurred in the briar. The reanimated bones of adventurers act animalistic, despite it being composed mostly of plants.
Festerfly	2	The Corruption	The putrid scent of the corruption was bound to attract flies, and sure enough, it did. Now corrupted and ravenous, they follow the scent of any fresh meat they can find.
Flesh Hound	2	Blood Moon	A nasty prowling canine that rears its head only under the vermillion light of a Blood Moon. Though it may feed, the hunger will always remain.

Gale Snail	1	Surface, Rain	A modest little nimbus that can't get enough of the rain. Even its shell produces rain, when it gathers enough moisture.

Ghast	2	The Dungeon	A master of illusionary spiritual arts. They will summon violent apparitions in an attempt to distract and overwhelm you.
Ghast's Spectre	1	The Dungeon	A convincing apparition summoned by Ghasts, made to do their bidding. It's merely a mirror image of the real deal, don't be fooled!

Glade Wraith	2	Briar	Despite the Briar's unnatural creeping presence, it has left its mark on nature just long enough for these vengeful spirits to call it home.
Gladiator Spirit	2	Marble	Be wary of this spirit, they have the unique ability to fortify their nonexistent bodies, making them resistant to damage, destroy their armor and release their soul!
Glitterfly	2	Mystic Moon	Glitterflies do not feed often, as their palette consists of a rare fungus. In addition, they possess a venomous sting that causes intense disorientation and vertigo.
Gloop	2	Asteroids	No one's quite sure what these things are made of. Whatever it is, it doesn't taste good.
Glow Toad	2	Mystic Moon	Psychedelic fungus grows upon the back of this toad. They are lost in delirium, as they find themselves snacking on it frequently.
Gluttonous Devourer	2	The Underworld	You'd best avoid the searing hot jaws of these beasts. Devourers have a notoriously painful bite, but that makes it a sought after material for the bold.
Goblin Grenadier	1	Goblin Invasion	When spiky balls aren't cutting it, good old fashioned shrapnel-spitting explosives should do the trick.
Gold Lumoth	4	Caverns	Rarely, critters are found coated entirely in gold! Shopkeepers will pay handsomely for these, or you can show them off in cages!

Hookbat	4	Surface, Nighttime, Rare Creature	These simple thieving pests decided 'divide and conquer' was a solid strategy after stealing the adventurer's cloth.

Molten Core	1	Meteor	A bubbling mess that escaped from within the meteorite. It appears to have basic spatial awareness and even some sentience. Perhaps it was chased by the invaders to the meteor?

Orbitite	2	Asteroids	This insignificant asteroid orbits a larger body, but will one day leave the nest and drift into the vast universe.
Palecrab	1	Ocean	These adorable little critters are not as hostile as their larger relatives. Living in deeper waters has made them lose coloration since they have less exposure to sunlight.

Red Snapper	1	Ocean	Despite their name, they are actually quite docile! Perfect for capturing and cooking without issue.
Rockfish	5	Caverns, Rare Creature	Undeniably too tough to eat. For bludgeoning, however, these natural disasters have quite the potential.

Skeleton Brute	2	Blood Moon	As a specimen, yes, they're intimidating. In a swinging match, nobody swings like a Skeleton Brute.
Snaptrapper	5	The Jungle, Rare Creature	Very little has been observed about this shrouded creature. It is six legged and bears claws, leading most to believe it is some form of arthropod.
Snow Monger	3	Frost Legion	A dangerous hovercraft made of spine-chillingly cold metal, and powered by Frost Cores. Playtime's over, no more mister ice guy!
Soul Crusher	2	Underground Spirit	Stones given life by thousands of souls, they angrily ram into any nearby disturbances, as it is sensitive to them. It shares the senses and thoughts of every soul that composes it, causing it great pain.
Soul Orb	1	Spirit	A soft, flickering light anomaly drifting about the Spirit. They are said to be the wandering souls of departed travelers.

Spirit Bat	2	Underground Spirit	Chunks of spirit-infused metal concentrated into the vague shape of a bat. Likely a lost soul's attempt to emulate the common flying mammal.
Spirit Floater	2	Underground Spirit	Floating slabs of runic stone now given sentience by the Spirit. Despite seeming hostile, it only wishes for peace to lay and rest eternally once more.
Spirit Skull	2	Underground Spirit	They only look like skulls, but in actuality are once again stones carved many centuries ago. These stones seem to be carved in such a way for souls to be able to inhabit it, yet there's seemingly no record of the Spirit existing prior to its release.

Stardancer	2	Asteroids	Strange mechanical constructs assemble around a beacon, calling attention to precious astral metals. It seems you aren't the only one who wants it.

Trochmaton	2	Marble	Times grow dire, and I must hurry. Dual blades, for attack. Four legs, for stability. Extra plating, for resistance. A marble core and at last the spark of life. Make haste o' guardian, you know your task. Defend these caves we call home.
Tubeworm	1	Ocean	Deep below the glimmering tides, down where the light won't shine, live some fascinating creatures, able to feast off of the smog exuded from hydrothermal vents.
Undead Scientist	1	Surface, Nighttime	An unholy practitioner of a necro-alchemy, combining typical alchemy with a form of minor necromancy in order to keep its sick experiments going.

Wandering Soul	2	Underground Spirit	Now being free from its slumber, it aimlessly wanders, forever lost in a world it no longer recognizes.
Wheezer	1	Caverns	A wheezer is an extremely toxic relative of the salamander, known for aggressive behavior. Oddly enough, their favorite food is a budding holly plant, contradictory to their carnivorous tendencies.

Winterborn Herald	2	Underground Snow	Long after forseeing the destruction of their tribe, these once elite mages now follow in the footsteps of their brethren, seeking to rebuild.
