This is everything that Darian writes in his diary(attention this might contain spoiler as it gets updated everytime he finds something new).
Snowy (met in chapter 1):
'This creature I've named Snowy is unique. It seems to have ice powers that channel through its body.
It doesn't seem like it can use them alone, it needs a host to fuse with to unleash its true strength.
Habitat: Unknown. It adapts to any climate, from extreme cold to heat.
The laws of physics don't apply to the creature. Sounds weird, right? But that's how it is.
I still don't know where it came from, but it doesn't seem alive in the traditional sense.
No organs. Just snow, layered and packed.
When it fuses with me, its body shatters and embeds itself into mine, possibly flowing into my veins and freezing them from the inside.
The nine tails stay fixed at the entry point. They are the key. They shape and launch the ice magic.
POSSIBILITY TO SHOOT ICE FROM MY BUTT???'
'I decided to classify the krukins from 1 to 4, each level rapresents the difficulty level.
the krukins level 1 are the weakest... the one level 4 is the worst one.'
'KRUKINS LEVEL 1'
Krukspy(met in chapter 2):
'Krukin category = 1.
These creatures are the most common krukin you can find out there, in fact, every single step you take, you can see them.
They don't have a face, and they aren't really dangerous, their body is extremely weak, except for their horn, this one is their strongest part. If you get hit by this horn, the poison will spread throught your blood and paralyze the place where you got hit.
These krukin have 8 legs and their body is right up these legs, and up the body you can find this horn.'
kruksnail(met in chapter 2):
'krukin category = 1.
These creature have a snail body type, in fact they even have a shell!
Their shell is extremely hard, I tried to cast multiple ice shards but it cannot be destroyed.
Their weak part, is their body, which is really dangerous, it created a weird and corrosive acid, it can easly go throught your skin. Everytime they pass around they leave the acid, and if you'd try to kill them, their bodies might explode.'
Kruktopus(met in chapter 3):
'krukin category = 1.
These creature have an octupus-like body, I don't know much about them, they are only found in water, rarely on the surface.
Their tentacles are extremely strong, they were able to hold my leg and I couldn't move it anymore.
Their weakest point is their head, which is really big and you can hit it easly.'
krukdill(met in chapter 7):
'krukin category = 1
These creatures are extremely dangerous, from all the level 1 I classified, these are the most strong. They don't walk normally, they have 3 wheels under their body, which can be charched to move faster. Charging the wheels takes a bit, during this time they are vunerable.
ONCE THEY START MOVING THERE IS NO STOPPING THEM!!
They have a huge drill that replace their face, this drill is extremely hard and cannot be destroyed.
Their weakest part is under their body, between the wheels, many attack can pierce into it.'
'KRUKINS LEVEL 2'
bladekruk(met in chapter 1):
'krukin category = 2
This is the first krukin I met on the earth... and it gave me chills, these creature are extremely dangerous.
I usually found them alone, but rarely they hunt in groups. These krukin have got a blade, that starts from their shoulder and goes directly to their knees. This blade is really strong, it cannot be destroyed in any way and, rarely, they use it to slide on the ground.
They have got a face, but it's really hard to tell what they are thinking.'
krukwyve(met in chapter 23):
'krukin category = 2
This enemy is around 8 feet tall, this is one of the first specie I encountered who can fly around, they have got huge ears, they probably hear everything around them.
In fact now that I think about, it's obviously that they didn't fall for Liro's illusion, it did not make any sound. They have really sharp teeth, the fur on their body is really similiar to the one of a wolf. With their body they are really similiar to a wyvern, also if they are 100 times smaller.'
'KRUKINS LEVEL 3'
krukmongbee(met in chapter 21):
'krukin category = 3
While it's body might seem similiar to a bee, it is in fact 100 times bigger and dangerous, I don't know how this is possible but this creature can create infinite stings that can be shooted.
These stings are really hard and cannot be destroyed with anything, they carry a posion too.
This monsters can fly, but their wings are really weak, they can be cutted down really easly. Their arms are really dangerous, they are extremely strong and with punch they can make the ground shake.'
'ahhh I studied this krukin with my friends... I was so happy, it was the first time I did it!' -Darian note.
Krukwomy(met in chapter 28):
'krukin level = 3
This krukin had the shape of a worm, and it could move really fast, this type of monster can easly dive underground, as Kael told me, once they move inside the ground will shake, it felt like a true earthquake. It is around 30 feet long and his skin is extremely hard.
Vane could barely pierce into it with his horns.
The strangest thing of this creature is his tongue, which has got the shape of a spear, his saliva is like acid, is too much dangerous to touch it.'
'KRUKINS LEVEL 4!!!!! ATTENTION!!'
???(met in chapter 2):
'krukin category = 4.
I don't even know where to start... this creature is not normal.
It had two different types of arm, one was really strong and muscolous, on the other one... there were tons of tentacles.
Everytime this creature took a step the whole ground shakes... it had so many different legs.
On his body there was what it looked like a mouth... but inside of it many tentacles were coming out, I thought that they might come from other mouths inside of it.
It was around 160 feet tall... no, probably even more, I could not even see it's face.
I wonder where this creature is hiding... oh right I forgot to mention that this creature had a weird green luminescent thing inside the the big mouth.
PROBABLY IT'S CORE?!'
'GENERALS'
'Eyrunik: Extremely big and resistant. Very slow, it can easily resist Kael's gravity and fight against Allocen's golem. It had some runes on its body, but we don't know what they were for. He is really slow, without Garwhole on his shoulder creating a wind, he probably would not be able do move this much faster.'
'Garwhole: Really small, it looked very fragile, but it was fast. It could move its wings extremely fast. The wind it created with them was far stronger than the one made by the Krukwyve. He probably rules over them because of their similiriaties, he also got surprised after seeing Bianca turned into a krukwyve.'
'The one fought in the water caves(name???): This one was strong. It had two sharp nails on each hand that could pierce a polar bear's body. It was extremely fast but not very resistant. It could make its rib cage come out from its back.'
'Leobruns: This creature has the shape of a lion, but it can stand on two feet and wields a katana. I don't know if it's his only weapon, but he was extremely fast. His armor is basically unbreakable, but his skin was extremely soft, at least this is what Alerya says, I don't know if she was able to deal such a damage because of her power...'
'Rhihamr: This creature has the shape of a Rhihorn, but it stands on two feet. He wields a hammer, he used it perfectly, he probably only used that for his whole life. He can create multiple fissures in the ground, and when he slammed it with all his strength, he created a whole earthquake. It seemed the hammer was made of stone, the stone and minerals on the black planet must be extremely resistant, I wonder if we would ever be able to gather some of them.'
