My point is that you can build very high off the ground with wood/iron and still get blue (grounded) connections with standard wood or core. For instance roof pieces are made from regular wood. I once made a three floor castle (counting the roof) (4 if you count the towers) out of only stone and wood/iron. It was massive and had no center supports. A stone floor will work as a roof for the purpose of the “shelter” effect.

Would not be nearly possible without wood/iron

Also wood/iron allows for something like 15 or 16 connections before you no longer build , pretty sure stone will not get you that far. And stone columns cannot be placed horizontally

I'll do some more testing in conjunction with core beams to see about supporting stone floors. Obviously, I'll still need to build an actual roof since, last I tried, my workbenches didn't respect stone floor as a "roof". Obviously there is a lot I need to learn and consider in the building system. I'll keep experimenting. Thank you for the tips!
