The Metamorph Device was included in Life Kit #1 for Creatures 2. It changes the gender of any creature it is used on. It is commonly used by Ettin and Grendel breeders to create a breeding pair. You can download this at the official site. Two versions are downloaded: a humane one which kills the original norn immediatly without a headstone, or another which severely damages the original norn, but allows for a headstone. The choice is based off whether you can stand to see a norn suffer and whether or not you want/need a headstone. Free to download, however, Life Kit #1 from Creatures 2 Deluxe has the metamorph device included.
