Fallout Shelter SPECIAL

This page describes the SPECIAL 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.

Intelligence
Intelligence determines the effectiveness of medbays and science labs. Intelligence also increases the speed of crafting in the Weapon workshops for 13 out of 175 weapons and for 18 outfits in the Outfit workshop.

In the wasteland, intelligent dwellers have better chances at succeeding in encounters with wounded civilized persons (such as injured sheriffs, wounded slaves, etc.), as well as dealing with certain enemy types. Dwellers with high Intelligence also have an increased chance of finding stimpaks and RadAway.

Dwellers can improve their Intelligence in the Classroom.

Agility
Agility determines the effectiveness of food production rooms (diner and garden).

In quests or in the wasteland, it determines how many shots dwellers can fire before the enemy does (effects how quickly a dweller fires their weapon) or how much damage the dweller can avoid when fleeing from hopeless battles.

Dwellers can improve their Agility in the Athletics room.

Luck
Luck determines if a production room also yields caps along with the normal room reward (or extra caps after a successful rush attempt). Luck also affects the chance of rush attempts succeeding.

In the wasteland, it increases the chances of finding items when dwellers go out on quests and explore locations in the wasteland. The higher the Luck, the better the items. During quest combat, it increases the speed at which the critical hit meter fills. In the wasteland, it increases the caps found.

Dwellers can improve their Luck in the Game room.
