Okay thanks, I've added "Human 0" as an option on the drop down. It gives no bonuses at all.I am also trying to convert a Giant Centipede from Labyrinth Lord and it says save as "0 level Human".
You are right. 1 Skull creatures have all their attacks being 1 Skull.One question I did have is that you mention 2-3 monster attacks should be weaker than the monster's overall difficulty rating. How do you implement this for monsters that are only rank 1 difficulty?
