Building multiple-level staircases in Palworld is possible, albeit not the easiest. The mechanics are a bit clunky for building, and you cannot directly connect two staircases together like in similar survival games (think Ark, Rust, etc) UNLESS there are ample foundations and ceilings in the vicinity.
To get your stairs to connect, you must have at least a landing to connect them to, and walls to support the length. For example, you cannot have floating stairs down to the ground (and since there are no pillars, you must use walls/ceilings/foundations).
Here’s a view without full walls to get an idea of the structure.
Two-stories inside is relatively easy. Just build up your house and you should be able to place the stairs. There is a bit of a jutted appearance and they do not match up perfectly but it is as good as it’s going to get for now.
As for the outside… I had to get a bit more creative.
For this, I simply made a box and connected it by layering the levels.
The hardest part of this connection was getting the ceilings and the foundations just right since they do not natively snap together. Hopefully this becomes a feature. For now, I had to keep placing foundations and trying to get them the right height/distance until I got them lined up enough to work with. It took about 20 minutes, but I was also being a perfectionist about it.
A couple things of note:
- Use the mouse wheel to rotate foundations just right.
- You might have to delete a lot in order to get things perfectly aligned. To delete structures click B for build and then C for destroy mode. Once in this mode, left click to destroy highlighted items. To stop, use escape.
- To move from different building items, use the mouse wheel for up and down.
- You can build freely with your box materials if inside your base (you can also build in the surrounding area of your base with these so long as YOUR CHARACTER is standing within the blue circle).
