My first thought was, "Woah, crazy powerful. I like." My second thought was, "Woah, crazy weak. No like." Currently she/it is almost impossible to lose against, since the final battle attack can't actually do anything put strip you down, which I don't think was your intention. Perhaps you meant to add a line akin to "If you cannot, you are Devoured" or somesuch? Otherwise she'll just get slowly punched to death (Or even worse, eat everything and have nobody left that can even roll dice against her, ending in an eternal stalemate).
Other than this oversight, I really like it. Servant of Chaos is wicked, haha.
