Fetching a high price by assassins and apothecaries alike, this venom is often seen as a quick way to make coin, alluring bold hunters to venture into the wilderness to harvest it. However, even in a juvenile state, these scorpions can deliver deadly stings and are faster than most men. What's worse is that they can live in rather large nests, and angering a seemingly lone scorpion can lead to swarms of them crawling up from the ground — quickly turning the hunter into the hunted. They are protected by a sturdy shell which hardens as they age, becoming more resilient. This carapace is very resistant to normal blade strikes or piercing attacks, but can be broken with heavy blows."
