Crafted with 8x Nails and 8x Wooden Planks.
A carpentry level of 3 is required to build.
When stairs are built there is one tile of plank floor attached to the top so you can progress to the next level and not immediately fall off.
Stairs may be built in 3 shades, dark, brown, and light brown. The difference is only artistic.
Stairs can be used to access or create higher levels on buildings or fortifications. Be advised, stairs are somewhat unpredictable and buggy, so death may be a result of careless use.
