New Countermeasure for Undead Hordes

So I have bred a brand new creature to deal with the hordes of undead. Before you say: “Wait that’s just an ordinary basilisk!” Stop. It is not. This particular breed of basilisk has been bred so that its gaze does not turn flesh into stone. Instead it turns any bone into stone within sight. The gaze is always active but admittedly only has a range of about a quarter mile. Stick that his more than enough for it to turn entire armies of undead into fossils. I call it: The Paleolisk. I am accepting orders today. Prices start at 100,000 platinum since I am still building the breeding stock up.
