Bota Bag

Thirst on a long roam is what it fixes. Fill it at a river or lake, keep it in your hotbar, and you drink when you want to instead of when you happen to pass water. It costs ten cloth and no bench, so a fresh spawn can have one before the first hut is up.

The controls are in the game text: left click drinks, right click fills from a water source or pours it out. Pouring matters more than it sounds, because whatever you scooped last is what you drink next.

That is the trap on the coast. Dip it in the sea and it fills with salt water, which takes health instead of fixing thirst. Picture a beach spawn in the desert with no river in sight: fill from the waves, drink, and you are worse off than before. Walk inland to fresh water first.

Once metal fragments stop being scarce, a water jug holds five litres by its own text and suits hauling water to a farm. A small water bottle you find works the same way as the bag, so there is no need to carry both.
