* Provides an indefinite amount of clay.
* You can raise clay tiles by dropping [[Pile of dirt|dirt]] or [[Heap of sand|sand]] on the corners.
* '''Be careful when dropping dirt, as raising a clay tile cannot be easily undone'''. If the northwest corner is adjacent to terraformable [[tile types]] that corner can be lowered through digging.
* Clay tiles can be lowered using the [[Level]] command if all corners are higher or level to an adjacent flat tile. A digging skill of 70 is required to do this.
* Digging the other corners will lower one dirt every 50-100 dig actions.
