Fresh water is the item that is the focus of the VacPack upgrade, Water Tank.
Sources[edit | edit source]
Once you find a source of water, hold the assigned 'Vac' key or button, and, assuming you have the Water Tank upgrade, the Water Tank slot should start filling up with water. There are several ways to get fresh water, constructing the Pond on a plot of land (which automatically fills), or finding it in the Far, Far Range, through Geysers and naturally occurring fresh water pockets, in which Puddle slimes naturally spawn in. Note, this is not referring to the vast and player-lethal Slime Sea.
The naturally occurring Fresh Water springs and ponds exist in multiple Zones throughout the Far, Far Range. Notably being the one(s) in The Dry Reef Island, The Indigo Quarry, The Moss Blanket, The Docks, and other lands.
