Quench

Quench is now called "Thirst" in the latest build.

Quench is drinking liquid. Liquid prevents death.

Healthy Drinking
Osiris: New Dawn abstracts liquid into a single indicator: Quench. Each liquid has a different quench value (which can be increased by processing it at a kitchen or Chemistry Table) and, of course, has to be drank to have an effect. Staring at liquid all day long will only fill your poor astronaut with longing.

Finding Liquid
You need to harvest hydrogen and oxygen with some barrel from geyser spread across the surface of Proteus 2. After that, you'll need a Chemistry Table or Chem Station and a glass container to produce water.

Alternatively, use the empty glass container and fill them with sap from trees then drink it, will be better that dying of dehydration.
