Variations on this get asked alot so I'm borrowing someones info from another thread.

You'll see there are several flavors of events that don't trigger until bonemass is defeated. It's nothing gamebreaking.

I'm one of the people that sometimes skips Bonemass and it has a huge benefit of never enabling the 'you are being hunted by wolves' event, that I consider to be one of the most dangerous because it can happen anywhere.

You should note that killing moder will enable 'the goblin army attacks' event. If you have been getting by with so-so defenses before, you might want to upgrade things.
