Mysterious Serum extended
This is a simple mod that I made for myself and decided to share. All it does is extend the duration of the Mysterious Serum from 1 hour to 416 days.
Lorenzo will give you a vial of serum as long as you don’t have one in your inventory. Since taking extra doses of chems in Fallout extend the duration. You can always request a vial, use it, request another vial, rinse and repeat. Doing this over and over again to extend the duration of the Mysterious Serum. This just saves you the trouble of having to do that.
Update: Upon request I added an optional file that makes the duration a week.
