Are devils worth 7 blood each?

[Huzurdaddi]

I think that they are worth 7 blood gems a pop. I think that they are fantastic units. I actually think that 7 blood gems a pop just about the correct cost, not too high not too low, just right.

The problem is if that's the correct cost then why do soul contracts cost so little?

For the paltry price of 60 blood ( you *really* should be able to forge a hammer if you are going blood ) you get 1 per turn. That pays for itself in 9 turns. This is much faster than other income generating types of investments.

Clams take ( assuming alchemy from astral -> water ) 14 turns to pay themselves off.

Fever Fetishes take ( assuming closed loop via alchemy again ) take 20 turns ( but really people probably do not close loop these ).

Vampires pay off in ~ 14 turns.

It just seems like the price of contracts is a little too low. If the requirement was 6 Blood to make them the cost 125 slaves which means it would pay off in 14 turns almost exactly the same as other income streams.

I just don't see why these things are so inexpensive. I just won a game based on them and really they are quite powerful.
