After lending the game to my friend it seems the rulebook for this expansion went missing and since we cant find it i tried looking for it online, but i only found the rules and not the part with the dungeon maps.

Is there any way to get the full rulebook online?

No. Not legally, anyway.

You can contact FFG to ask about a replacement book; they might have some lying around.

I thought that was the case... well i will try to contact them then.

Thanks for the reply
