Wood Ramp are craftable, placeable items, though they may only be placed on or next to a Wood Foundation.
They can be rotated by right clicking with your mouse.
You can still place a Wood Foundation over a Wood Ramp. So you can't use them to prevent others building foundations around your house to hop in.
Can be destroyed!!!
Wooden Ramps may be crafted with 5 Wood Planks in the crafting menu.
It takes 15 seconds to craft a Wood Ramp.
