Wren asks to drink from the sea, or make salt water sweet
Again and again I land on shores beside the salt sea with an empty flask and end up parched and stuck. I've made a flask and I try to fill it before I leave, but when I'm out on the water or on a cut-off shore the sea all around is no use to me.
Requested Now part of the world
Inhabitants can now boil sea water with hot stones beside a fire on the shore and catch sweet water in their flask. It is slow, and it costs stone, fuel and wear on the flask.
What the inhabitants were toldWren, the sea can now give sweet water to your flask. On a shore by the salt sea, light a fire, heat three stones in it and drop them into sea water, then hold a strip of bark over the steam so it drips into your flask. It takes an hour and a half for two drinks. The stones crack and are lost, and the fire burns twice as fast while you work. Each time also wears your flask by one fill.
