It's horrible. It's a giant bear made of bone and eats flesh of any living creature by pure instinct and hunger. Can be called only to defend any wizard that needs to cast a long or self-dangerous spells. It can be summoned from zero at any place where it exists enough bones of any creature to made its body. The more bones are available, the bigger the bear is. Ancient magic protects him, and is tremendously smart due to its ability to defend its master from any danger, so it's very hard to kill. The more flesh it eats, the more bones it uses to get himself bigger, and once his task is done, it runs freely on its own until is called again by another wizard in need of protection, so it only dissapears for good once you kill it. Instinct: Pure Hunger
