Transmutation liquids are used to change one type of tile into another type of tile. They are most often used to create convenient sources of uncommon resources (such as [[tar]], [[peat]] or [[clay]]) on or close to players' deeds, or to revert such resources to dirt to allow building or paving.
Transmutation liquids can be '''passive ''' or '''active'''. Any priest can make a passive liquid active with the [[Bless]] spell. Only active liquids can transmute tiles.
