I have been crafting all three types of walls. I used the iron and gargoyle walls for my cemetery area, which I was able to expand with the new walls. I like having walls in storage for expansion if new things come out that I want to incorporate. I have also crafted some bats and brambles because I wanted more when I was designing earlier and now can place them. I would rather have too many of things that I think I can use then not be able to finish my design because I am lacking.
