13: Make the World a Better Place (YAHF)
YAHF AU fanfic.
Xander dresses up as an alchemist, at the same time as a master alchemist goes on a dream quest. This puts Xander in the Alchemist's tripped-out body, leaving him nothing but a deep understanding of alchemy and a cottony tasty in his mouth when the night is over. However, the alchemist (on reviewing Xander's life) uses the clarity of the dream-quest and his own knowledge to cook up five batches of DREAM and (seven?) doses of WISH, which is what Xander discovers when he wakes up. As such, besides the EXCEPTIONALLY rare and hard to craft WISH, Xander finds himself able to craft and tame monsters, empower humans, and use alchemy to play god.
Concoctions WISH, DREAM, and several others: Magic Spreadsheet, Usable Drug Ideas
