Salve sodalis,
We built a Spring Covenant using the rules in the Covenants supplement. And thanks to a great location, we had access to more Hooks than we could bank.
So naturally, one of the Boons we chose, was Hidden Resources (Minor Resources Boon, page 18: 250 Build Points that we turned into 50 pawns of various types of Vis per year). Now, after about six years in-game campaigning, we have a huge stockpile of Vis since we don't seem to do anything with it. Occasionally we heal one of our grogs or trade some raw Vis to borrow a tome from a friendly covenant, but that's about it.
Obviously we're doing something wrong. I know we could use Vis to make magic permanent, but we seem to never have a need for that. None of us is close to needing a Longevity Potion either.
So, Vis doesn't feel precious to us. What should we do to change that? What are we missing?
