I don't like that stinger. The stinger was as large as a knife, and on top of the fact that if it went deep enough he would bleed out anyway, even though the stinger was so large already it would most likely be dwarfed by some of the larger predators. Which meant it probably had some sort of poison. So let's avoid that if we can, shall we? He lunged in, aiming his spear for the multitude of eyes, and quickly darted back out, narrowly missing an even quicker slash from the stinger. Annoyingly, he had missed the eyes and glanced off of some of its exoskeleton, probably meant for just that purpose. This time the scorpion made the move, attempting to form a sudden hole where his heart used to be. He dodged to left, landing awkwardly on his leg, causing him to grunt in pain and stumble over, allowing the scorpion to walk over, however just as it began its strike, a loud roar diverted its attention. As it began to turn mid-strike, it only caused a scratch on his arm. He suddenly felt his arm run cold, and then it spread to the rest of his body, and as he blacked out, he thought, Is this what it feels like to die?
He woke with a start, remembering what had happened. He realized the poison was not deadly, just a fast acting narcotic. That could be very useful. As he walked out of the cave, he noticed something shining where his spear had scratched a rock as he fell. It appeared to be some sort of metal, maybe he could use this sometime. He noticed a yellow streak on the rock in the same place the metal was on the inside. That could be useful to identify similar metal rocks. Then he noticed as he looked around that almost every rock had those streaks. Very nice. He found the scorpion dead a few meters outside the cave, with two clean bite marks straight through it's chest. He decided to inspect the place where his spear had glanced off its armor, just to see. There's not even a mark! The exoskeleton had completely negated the damage. If I could turn that into some sort of armor, it could sustain some real punishment. I may not get another chance like this without being seriously hurt. I better keep this safe until I can find a way to get this armor off. He vaguely remembered something he had learned about… xitin? shitin, no, chitin! Yes, chitin. I remember because I always had to think of it as kite-in, because I always called it ch-itin. He figured that if he could get a sharp enough axe, he may be able to pry off the tough armor.
