It treats most traps as garbage strewn on the ground, but witchers may be able to construct traps to immobilize its tentacles. Unfortunately it is a monster that makes other monsters seem like house pets, thus oils reducing blood coagulation cannot harm it. If the creature had a circulatory system like humans do, it might be possible to bleed it to death. It might even fall over from laughter, and that would be the only way to knock it down, but it's not going to happen. Good luck! The kayran laughs at poisons, or it would laugh if it had a sense of humor. One needs to find a way to pierce the carapace and get to the inner organs. Its armor, tougher than that of any other creature - with the possible exception of dragons - is the final obstacle to overcome. Once the kayran is unable to shield itself, one should approach its trunk - but beware its venom! The monster spits its vile poison as skillfully as a street urchin. These tentacles should be cut off or immobilized during combat, for example using a special trap. The creature defends itself with long, heavy tentacles - and ordinary man would die from a single blow, for these appendages weigh as much as a trebuchet arm and are covered in poisonous mucus.
If that trick works, it will be possible to approach the monstrosity.
To defeat the kayran, one first needs to pull it onto dry land or drain the river meander where the monster lies in wait. Even the military cannot handle this plague, for the kayran hides in the water, where it is impossible to fight. It has become aggressive: it shatters ships, shreds nets, snatches people from the river banks and pulls them beneath the water. Lately, however, the kayran awoke and now emerges from the water. Until recently, they even considered harmless. People have grown used to the monster's presence. The folk of the nearby village call it the Old Man. Over a hundred years ago the kayran made its lair near the trading post of Flotsam. There is no certainty whether it is the same creature slowly moving up and down the river, or perhaps his progeny seen here and there. The chronicles mention instances when the kayran appeared on the river's surface in various places over the ages. It took up residence in the Pontar's waters, where it lives to this day. Doubtless it is a post-conjunction creature that appeared in our reality in the time when worlds intermingled. Journal Entry The kayran stands apart among all creatures, large and small, beautiful and horrible: it is unique, not alike any other being.
