As far as I know, Mist in a Bottle has been a non-functional item since the last major sailing update, nearly a year ago now. It still drops in chests, but currently has no practical purpose.
- Mist could function as a unique weather effect on the sailing map, similar to storms. Ships inside mist wouldn’t appear to others unless they are 1 tile away, creating a tactical way to hide or evade.
- Mist could naturally form like storms and drift with the wind across the sea map. Alternatively, players could release it using the item to create temporary cover or confusion.
- Natural mist patches could feature increased chances of rare or supernatural encounters, like ghost ships, undead galleons, or other themed dangers
