Are devils worth 7 blood each?

The relative worth of astral vs. water is quite dependent on the nation, but IMO it's clear that for any clamhoarding nation (which is what we're talking about in this case), the water is worth more than the astral.

I don't think so. They're making clams _because_ astral gems are more valuable to them. After all - compare to fever fetishes. If you run a surplus of fire gems, but need ... air, you have to convert 4 fire for each air gem. The astral gems are more valuable because they're essentially worth twice as much as any other gem when alchemizing from one to another.

I say this as someone who has clammed, and who has fevered, and who has had at least something like 40 fetishes and 40 clams going in the same game, with a non-fire, non-water, non-astral nation, without ever alchemizing to build the fetishes or clams.
