Chicken Chasing
Brunhild counts out 25 gold coins and hands them over to Stalsii. She seems slightly alarmed and looks over you all again, "Well, with most cockatrice, the bite will cause the petrification for 24 hours after which they return to normal. But Chukchuk here is different due to the experimentation I've been conducting. If he scratches you, rather than biting, for those around my size whatever was scratched, an arm, leg, foot or otherwise, would petrify for 48 hours. However, if I, for example, get scratched enough, then the petrification would spread to my whole body. A...verdan, I believe you're called? or one your size would be fully petrified. Regardless, the effect should fade after 48 hours time.
"I've succeeded in lessening the immediate potency of Chukchuk's magical petrification but at the trade-off of the duration, for the time. Hopefully, with some more research and testing now that you've returned him, I can figure out how to lessen it more and more, if not negate it completely. Unfortunately, beyond Chukchuk escaping, some of the materials needed to really dive into the experimentation are more difficult to come by."
