Attaches to a large tree, enabling you to build on it.
Structures such as the Stone Wall and Wooden Wall cannot be directly placed onto the Metal Tree Platform. In order to build on the platform you must first place a foundation such as a Stone Foundation or Wooden Foundation, and then you can place other structures on top of it. Walls will not snap to the edge of the tree platform; however, placing Fence Foundation will allow walls to be placed at the edge of the platform.
It is possible to place crafting structures (Smithies, Forges, etc.) directly on the platform.
The platform doesn't have any snap points (No ladder or wall placement along the outer rim.)
