It’s really unfortunate. Aesthetically, I like how they’re kind of this semi-makeshift line of rocks in the ground to discourage people from getting in but aren’t a serious defensive implement. In practice, they’re significantly more costly and time-consuming than a normal building wall and take a lot of time to place down, since you have to place them one-by-one. Like, it’s a serious enough discrepancy that I’m actually just as likely to assume I’m missing something than that it’s a design oversight.
at first they are decorativ ^^ so i use them mostly for my animals ^^
also you can download the mod endpieces where you can place 10 at one
They are good for fencing!
Anyway, Wiese2007 is right. You can grab the mod on Praise.
Additionally, unlike a regular wall, you can move and reposition then: a significant advantage
