This question already has an answer here:
I'm confused by the Crafting rooms - I vaguely remember seeing that the Weapon Workshop uses Agility at one point, but then it changed to Strength? I may just be insane however and imagining things.
So what stats do the Weapon Workshop and the Outfit Workshop use?
EDIT: After looking at the wiki, the crafting time suggests a possible maximum SPECIAL attribute being over 10, but this is not clarified as to which SPECIAL, or SPECIAL(s) - though I would believe this is likely contributed by gear:
Total SPECIAL = Crafting Time
102 = (x) mins
102/6 dwellers = 17 per dweller.
