With Faydwer not yet available on the progression server, acquiring pixie wings for spell research was nearly impossible. Only a single pixie made Tox Forest it's home. Fortunately Stofo Olan, visiting in the Vasty Deep Inn, currently has an abundance of pixie wings he is willing to trade for a local bloom. Dedicated casters may either hunt the blooms or hire young adventurers to seek them out.
Good luck casters!
