* '''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.
* Dropping clay does not create clay tiles.
* Clay tiles are found naturally, often below water level.
* Clay can be dug with a dredge from below water level
* Houses cannot be planned or built on clay tiles.
* Clay tiles can be converted to dirt via [[Transmutation Liquid liquid (Feature)|Transmutation Liquidliquid]]
