Endurance is one of the SPECIAL stats that dwellers have in Fallout Shelter. While this stat may not be useful early in the game, it is crucial for a certain room in the late game and for venturing into the Wastelands.
Fallout Shelter SPECIAL stats overview
In the future, it will be necessary to have dwellers with high stamina in your vault. Luckily, there is a way to train stamina in Fallout Shelter.
Stamina increases a dweller's hitpoints (essential to surviving the dangers and quests in the Wasteland) and is needed to increase the production rate in the Nuka Cola Bottler room in Fallout Shelter.
While the room in question is described as creating Nuka Cola, it does not produce Nuka Cola Quantum, which is an item that can be used to quickly travel around the Wastelands for quests. Instead, it actually produces both water and food, both of which are essential resources for keeping your dwellers fed and hydrated.
