Floor plan to create an opening with a ladder for multi-story buildings.
===UsageCreation===
* Right click the floor of the house, select ''Plan'' > ''Build floor with opening above'' to create a floor plan
* Right click the floor plan, select ''Build'' > ''Marble slab opening''
===Usage===
* Right click the opening or ladder, select '''Climb''' to move between floors.
* By standing on the opening of a floor you can activate a [[rope]] and right click certain items to haul them, providing both you and the object are on the same tile, albeit one floor apart. Hauling back down will work in the same way and the item does not need to be empty.
