For the Medbay (Stimpaks) and Science Lab (RadAway), Intelligence (I) is the most important S.P.E.C.I.A.L. stat. Dwellers with high Intelligence will produce Stimpaks and RadAway much faster. While other stats don't directly affect production speed, a higher Luck (L) can still provide critical hits for bonus production. Train your designated Medbay and Science Lab dwellers to have maximum Intelligence to ensure a steady supply of healing and radiation-curing items, which are vital for both vault incidents and wasteland exploration. These rooms are critical for long-term vault sustainability, so invest in your Intelligence-focused dwellers.
