Water Purifier

C Hydration maintenance

Mandatory infrastructure in the first 72 in-game hours. The Simple Purifier converts salt water to drinkable hydration, halting the aggressive hydration decay formula that threatens early-game survival. Upgrading to the Advanced Water Purifier (mid-game) restores a larger per-tick hydration value and unlocks consumable flask crafting. A non-functional Purifier is functionally equivalent to a death sentence in the Scavenger Phase.
