Properly formatting my vote:
[X] Plan Fields of Gold
[X] Take an active hand in the EIC
[X] Windreader > Windsage: Your magical senses see more than your normal ones. +2 Learning, even more able to see and understand emotion and magical effects in others
[X] Avatar: You're growing worryingly familiar with being used as a conduit by deities. ???
[X] Donate it to whoever ends up leading the Undumgi.
Assassin is amazing, but I figure it's going to be one of the more common ones. Windsage we absolutely cannot pass up on, and Avatar seems nearly impossible to show up again, and likely downright necessary for Sorcery, which might hold more potential than any other avenue of research, as negating Battle Magic miscasts is a game changer on the arcane dueling front.
