Ooops, sorry! Nope, that was just random. X3 Zandra has a couple of things that she can drop: a stinger, that necklace, a brown cloth cap - whenever you defeat her, you have a chance to get any of these. Same goes for Cladt - so if you didn't get what you hoped for (like if you wanted the stinger on your gal character), you can just pay her another visit. ^^
