In survival you have a health, hunger, experience, and air bar. But with this add-on you can now take one step further and add a thirst bar! The thirst bar will slowly go down over time and can be brought back up by drinking water bottles, potions, or milk buckets. Be careful though, because if your thirst bar goes all the way down you will die instantly. So drink water!
This will be added as an optional feature in Expansion+ soon.
