Cerastes

Cerberus is a unique three-headed dog with armored scales and a dragon’s tail. It is well — known as the guardian of hell; it lets spirits in, but none out. All around its neck are small serpent heads, which are not venomous.
Heracles wrestled Cerberus and brought him out of Hades at one point, without using any weapons. He was bitten terribly by the snake heads, but, as was his wont, continued on with his task. In the service of a master, it would be very loyal.
In the wild, it would live in any land habitat, and be active at any time. Any attempt to deal with the unique
Cerberus would be at a -4 to Animal Handling rolls. If there is a wild species of “cerberus" creatures, they
would still be at a -2.
Each head has full coordination, being able to bite into any front hex each turn. All three may attack a single foe only if he is in the hex directly in front of Cerberus. The snake heads can only attack in close combat. Assume that there are many — the number is never given — but that only four can attack a given character in any one turn.
Rumor: There are tales of Cerberus letting heroes by because they fed it. This would have to be either magical food or a lot of it, however — Cerberus is a big dog, and each head wants something! Whether the dog's friendly reaction is due to gratitude or simple satiation is not known
