* '''Tar''' is created from [[charcoal pile]]s, can be [[digging|dug]] from [[Tar tile|tar pit]]s or butchered from [[Spawn of Uttacha]].
* [[Tar tile]]s can be raised by dropping [[dirt]] or [[sand]] but they cannot be changed to a different tile type except for without using the [[Transmutation transmutation liquid (Feature)|transmutation liquids]]s.
* They can be lowered with the [[level]] command if all corners are higher or level to an adjacent flat tile and your [[digging]] skill is at least 70.
