Wild: Colossus Petram is like no creature I have ever encountered. There is no biological or historical precedent for it. Its nearest relatives exist only in legend - mythical statues that could come to life like the Golem of Prague. That makes it all the more dangerous. What survivor could possibly expect a seemingly benign rock formation to suddenly spring to life and attack them? Fortunately, Colossus petram's massive size makes it quite slow, so I would advise most survivors to flee immediately if encountering it in the wild.

Domesticated: If somehow tamed, Colossus petram could prove to be an invaluable asset, particularly in a siege. Only armor-piercing rounds or explosives can harm it at all, and it will handily smash through stone structures.
