Nature's Call is a Vintage Story mod by jayu and Bronze_Granum. Nature's Call adds a bladder mechanic to Vintage Story: hydration loss fills it, and players must relieve themselves or suffer reduced movement.
Why this mod is worth installing
This mod suits players who want survival to include another bodily need and more meaningful use for farmland, containers, and fermented urine. It works best alongside a thirst mod, though hunger can provide the fallback.
What Nature's Call adds
Your bladder fills as hydration decreases, with hunger serving as an alternative source when no thirst system is available. Once the meter becomes overloaded, movement is impaired until you relieve yourself.
Relief can be performed while crouching or standing, using the appropriate empty-hand interaction. A configurable keybind also lets you empty the bladder early, before the penalty becomes a problem.
The mechanic has practical consequences: using farmland may add nutrients to the soil, while a container can collect the liquid. Fermenting it in a barrel produces lant for soaking hides.
