SPECIAL Stat: Strength

This room generates power to the entire vault. As you add more rooms, the higher your power requirements will be. Like other production rooms, you can merge this room up to three times and upgrade it to make it more efficient. If you don't have many dwellers with high Strength stat, consider equipping them with Outfits with +S to boost their stat. This will help speeding up the production cycle of this facility.
