Description

The quality of the lye used to create the concrete affects your success chance.
Right click a cave floor tile or exterior rock tile with the concrete and select > raise corner - this raises the corner the equivalent of 1 dirt.
The corner closest to where you are standing will be the one that is raised, just like when dropping dirt.
Unsuccessful attempts result in the loss of .05kg lye and .30 kg mortar
Concrete can be used to raise an underwater cave tile as long as the tile is 25 dirts deep or less; below that you get the message: The water is too deep and would only dissolve the concrete.
Can be used to raise a corner to a maximum of 25 slope on PvP servers or 40 slope on PvE servers.
Cannot be used on any corner of a cliff tile regardless of slope.
If used to raise the corner of a surface rock tile, the surrounding area must also be rock.
