Wooden Wall

A  is a low-tier wall block that can be placed adjacent to any physical block on any side of it. They can also be placed directly on any  natural  dirt and stone back walls. These are the easiest blocks to create of all wall blocks, but are rather flimsy and can't support very much weight before collapsing. They are destroyed  very  easily and it is recommended you upgrade your structures from s to at least concrete walls as soon as possible.
