This mod adds a vendor in Goodneighbor that sells XP serums. They cost 10k caps and grant 5k experience. It designed with late game in mind, and gives you something to do with all your extra caps. (Finally a use for your water purification farms).
See the screenshots to see the location in Goodneighbor, this mod will be incompatible with anything that also edits that exact area. If there is enough demand, I can make a settlement version or something.
Installation:
Use NMM or drop folders in your data folder.
Thanks for downloading! Be sure to report any bugs!
(Also if anyone knows how to take that wretched radstag outfit out of his inventory please let me know.)
