Endurance/Fallout Shelter

This page describes the Endurance implementation

Background
Each SPECIAL attribute increases dweller efficiency in various rooms, during combat or when performing certain tasks. Although attributes can only be trained to a maximum of 10, they can still be increased to up to 17 through clothing bonuses. These additional points will not be visible on the dweller's SPECIAL bars but can be checked by tapping/clicking the bars, which brings up a more comprehensive menu that lists any and all bonuses.

Gameplay
Endurance increases the speed at which the Nuka-Cola bottler creates food and water. Endurance can also increase the speed of crafting in the weapon workshops for 18 out of 175 weapons. It is also the assigned skill for the storage rooms, although it will have no effect on those rooms.

Endurance determines how many hit points dwellers gain as they level up. Dwellers start with 105 health points. They seem to get 2.5 + (END * 0.5) health points each time they level up, so 17 points in Endurance will add 11 hit points per level compared to the minimum of 3 at END 1. This means that a level 50 dweller with 1 Endurance will have 252 hit points when at max level compared to 644 hit points, which a dweller whose endurance was maxed out at 17 from level 1 will have.

To achieve maximum health, a dweller must equip heavy wasteland gear (END +7) at level 1 while already having 10 points in Endurance themselves. At END 11 or more, the dweller becomes immune to the occasional radiation bursts they suffer while exploring the wasteland (note that this does not apply to real-time combat).

These hit points are not retroactive. Dwellers can improve their Endurance in the fitness room.

Formula
On each level-up Dweller's maximum HP increases according formula:

$$MaxHitPoints += (BaseEndurance + OutfitEndurance) * 0.5 + 2.5$$;

Dwellers with higher Endurance perform better in Nuka-Cola bottler.
