Started my first game last night. And one of the creatures used developed a random mutation. I used the Index to try and find the mutation rules and it mentions the Liber Mutatis. I do not have this product and I cannot find reference to it on the product range on the FFG site.

So where is it? How does one get it?

Thanks.

do you have Players Guide and GM Guide?

It's the GM's book in the Winds of Magic. You can also find the rules from the Edge of Night adventure.

I have the Core boxed set, the GM vault, Creature vault and the adventurers toolkit. Do I NEED the GM Guide and Players Guide as well to get the complete rules?

Well the priest set has diseases and the magic set has mutations (in addition to priests and wizards of course). Witch's Song has rules for Hedge Wizards. You don't actually NEED them but naturally (from the publisher point of view) they are quite necessary for gaining the whole experience.

And don't worry. I'm sure future expansions have something additional that makes the game even more exciting.

to be honest - yes. let us dont lie ourselves
