Gollaon ducked behind the battlement just in time; the sling bullet whizzed over his head to crack against the far wall. Gollaon started to reach down to pick it up.
“Leave it!” stated Voddick. “I have seen stones like that before. They sting with venom, nasty things.”
Golloan kicked it into a corner. “Vicious.”
Further down the wall, a soldier yelped and dropped the stone he just picked up.
“Guess I should pass on the warning,” grumbled Voddick.
Scorpion Stone
These bullets, usually made of lead but occasionally of fired clay, are marked with a venomous creature usually a scorpion. They should not be handled with bare flesh as they will sting anyone who does so.
