A Cistern is used to store water, and is created by adding a bowl of plaster to a stone pile (10 stones). An empty cistern can store up to 10 buckets of water. Only buckets can be used to add and take water. An empty cistern can be destroyed with a pick axe, returning the stone pile.
- Water is guaranteed to be taken out of a cistern with no "chance to use" factor.
- Cisterns are useful for transferring water to farms from faraway wells.
- As of v178, draining a water source no longer increases the rate of regeneration. However, adding or taking water will reset the regeneration timer of these sources, so it is recommended to empty water sources completely into cisterns to control for this.
